Exchange of Gifts

The USCCB Committee on Ecumenical and Interreligious Affairs runs more than a dozen ongoing dialogues. Most mirror the Holy See's international dialogues. (USCCB Ecumenical)

Sources: Committee History, Ecumenical Documents.

Framework of the basics

Note: Baptists generally do not use formal creeds, so frame these as shared beliefs, not a shared creed.

The Catholic recognition of Baptist baptism is a strong starting point: Catholics see Baptists as fellow baptized Christians. Sources: Baptist Faith and Message 2000, Catechism of the Catholic Church, To Understand Each Other (1989).

Further shared ground

• Scripture is the inspired word of God, authoritative for faith and practice, and central to worship and personal spiritual life. (To Understand Each Other, 1989)
• Offering salvation to all peoples is the prime mission of the Church. (To Understand Each Other, 1989)
• Common ground on marriage and family, social service, and public policy, with joint statements on the environment, poverty, racism, life, and sickness, disability and healing (1994–2001). (SBC-Catholic documents)

• Scripture and tradition: Southern Baptists test all tradition against Scripture alone and uphold individual interpretation. Catholics read Scripture as the whole Church has proclaimed and lived it. (To Understand Each Other, 1989)
• Salvation: what it is, how it comes, its means, and whether it can be assured. (Salvation conversation, 2001)
• Predestination, assurance, and justification. (1998 conversation)

Faith and works in salvation

Both agree salvation starts with God's grace, not human merit. They differ on how good works relate to being justified and staying in grace.

A bridge: Ephesians 2:8–10, a passage many Baptists know by heart, holds both sides together. We are saved by grace through faith, "not from works," and we are created in Christ Jesus "for the good works" God has prepared. The Catholic Church teaches the same: no one can earn the first grace of forgiveness and justification (Catechism 1996, 2010). This gives Catholics language a Baptist can recognize: good works flow from grace; they do not earn it.

Can salvation be lost?

• Catholic: A person in a state of grace can turn away from God through mortal sin: a grave matter, committed with full knowledge and free consent (Catechism 1857–1861). The loss is not final. Confession restores grace, and the Church calls it the "second plank" of salvation after Baptism (Catechism 1446).
• Southern Baptist: Once saved, always saved. All true believers persevere to the end; someone who falls away completely was likely never truly born again (BF&M 2000, Article V).
• Bridge: Both take sin seriously, and both trust that God does not abandon his children.

These differences are noted here only in outline. Most are shared with many Protestant traditions, so each will be treated in detail, with USCCB references, in a common section on differences.

• Mary and the saints
• The authority of the Pope and the Magisterium
• The Real Presence of Christ in the Eucharist
• Infant baptism and believer's baptism

Catechism references. Trinity (Catechism 232–267); Baptism, including baptism by non-Catholic Christians (1213–1284, esp. 1256); faith, grace, and justification (1987–2029); Scripture and Tradition (74–141); the Eucharist (1322–1419); separated brethren and the bonds of baptism (817–822, 838).

The Church receives Baptists as fellow baptized Christians, building on the faith they already have. In USCCB terms they are "Candidates," received into the full communion of the Catholic Church rather than baptized again (USCCB: Christian Initiation of Adults).

1. Formation. Candidates usually join a formation program within OCIA (formerly RCIA) to understand and experience Catholic teaching and practice (USCCB: OCIA).
2. Reception. They make a profession of faith, normally followed by Confirmation and first Eucharist.
3. Respect for their baptism. The bishops' National Statutes for the Christian Initiation of Adults set apart the preparation of validly baptized Christians from that of the unbaptized; the diocesan bishop issues norms for their reception (National Statutes).

Guidance for OCIA leaders. Church norms give those who lead OCIA specific direction for Baptist candidates:

• Honor their baptism. The reception of baptized Christians "should clearly be distinguished" from preparation of the unbaptized, "because those being received have already become members of the Body of Christ through their baptism" (Archdiocese of Los Angeles).
• Fit formation to the person. Per the National Statutes, "those baptized persons who have lived as Christians and need only instruction in the Catholic tradition and a degree of probation within the Catholic community should not be asked to undergo a full program parallel to the catechumenate." An active Baptist may be received on any Sunday after a short preparation (Blessed Trinity Parish).
• Use the right rites. The Scrutinies are only for the unbaptized, so Baptist candidates do not celebrate them (National Statutes, 3; Team Initiation).

For many Baptists, becoming Catholic brings real loss alongside joy. Catholics who walk with them should understand that grief and stand with them in it.

• Family and friends. Converts describe strained or broken relationships. One Baptist convert wrote that friends "no longer want anything to do with us," and that families "feel that we have betrayed them and the faith of our childhood" (Katie Plato). The Coming Home Network notes conversion "can cost them friendships, and even alienate them from their own spouses" (CHNetwork).
• Church community. A Baptist's whole social and spiritual world may revolve around their congregation. Some converts quietly drift from old friends to avoid burning bridges (John Litteral).
• Livelihood. Pastors, teachers, and ministry workers may lose their jobs. Marcus Grodi tells of a 59-year-old former Baptist pastor in Texas who could find work only as a greeter after converting (CERC).
• Loneliness. Staples felt alone on the verge of conversion and faced a heartbreaking decision (Jimmy Swaggart Made Me Catholic).

How Catholics can respond. Offer a new parish family, not just a class: sponsors, meals, and friendship that last past the Easter Vigil. Encourage converts to keep loving their Baptist family and never to speak ill of the faith that first taught them Christ. Point those who lose ministry careers to the Coming Home Network, which exists to support them.

Baptists do not come empty-handed; they bring gifts that enrich the Church. Vatican II teaches that "Catholics must gladly acknowledge and esteem the truly Christian endowments from our common heritage which are to be found among our separated brethren" (Unitatis Redintegratio, 4). St. John Paul II described ecumenism as an "exchange of gifts" (Ut Unum Sint, 28).

• Love of Scripture. Baptists know and treasure the Bible. The Council praised the devotion to Sacred Scripture found among separated brethren (Unitatis Redintegratio, 21).
• A personal relationship with Jesus. Their emphasis on personal faith and commitment to Christ echoes the Church's call to an encounter with Him.
• Zeal for evangelism. Baptists are used to sharing their faith openly, a gift for the New Evangelization.
• Prayer and fellowship. Spontaneous prayer, hymn singing, and close-knit community life can strengthen parish life.

OCIA leaders and sponsors should affirm these gifts, so candidates see that becoming Catholic fulfills, rather than erases, the faith that first brought them to Christ.

• Start with friendship and with Jesus, not with arguments. Many Baptists have heard that Catholics are not really Christians, so the first gift is simply to share your own love for Christ.
• Lead with shared ground. Begin with what is in the table above: the Trinity, the cross and resurrection, salvation by grace, and love for Scripture. The 1989 conversation To Understand Each Other models this.
• Honor their baptism. Tell them plainly that the Catholic Church recognizes their baptism and sees them as fellow Christians (Catechism 818, 1271).
• Open the Bible together. Baptists trust Scripture; let the conversation start there, with passages like John 6 or John 17:21.
• Ask, listen, and learn. Ask what their faith means to them and how they came to Christ, and listen before explaining.
• Never belittle their church. Speak with gratitude for the faith that first taught them Christ (Unitatis Redintegratio 3–4).

Baptists followed the Second Vatican Council (1962–1965) closely. The Council was the first to invite observers from other Christian churches. They could not vote, but they shaped discussion through contact with bishops and theological experts (Britannica).

The Baptist World Alliance chose in 1962 not to send official delegates. Baptists still followed the Council and took part as individuals (Christianity Today, 1965; Baptist News Global). For a later Baptist view of the Council, see Vatican II, 50 years later: a Baptist appreciation.

A Baptist voice: Steven R. Harmon. Harmon is a Baptist historical theologian at Gardner-Webb University. He served on the Baptist World Alliance delegation to official conversations with the Catholic Church from 2006 to 2010. On the Council's 50th anniversary (October 11, 2012), he wrote that this work gave him "a deepened appreciation for many aspects of the work of that council and its legacy." Elsewhere he notes that Baptists, lacking official observers, came to know the Council largely through second-hand reports, and that Baptist–Catholic relations have "made great strides" since. His book Baptists, Catholics, and the Whole Church: Partners in the Pilgrimage to Unity describes the two as fellow pilgrims toward Jesus' prayer "that they may all be one" (John 17:21). Sources: Vatican II, 50 years later; Baptists and Catholics together?

Book: Harmon, Steven R. Baptists, Catholics, and the Whole Church: Partners in the Pilgrimage to Unity (preview).

Harmon's argument in brief. Harmon's other books include Towards Baptist Catholicity and Baptist Identity and the Ecumenical Future. His central claim is that Baptists, though they sent no official delegates, were shaped by Vatican II. He points to the Council's renewed focus on Scripture, its picture of the Church as a pilgrim people, and its openness to other Christians, and argues these fit Baptist instincts. He also urges "receptive ecumenism": Baptists asking what gifts they can receive from Catholics, not only defending their differences.

• Tim Staples grew up Southern Baptist and served as Director of Apologetics and Evangelization at Catholic Answers until July 2026 and is now apologist emeritus (conversion talk).
• John Thompson, a former Baptist pastor, describes how the Church's authority, sacraments, and the Real Presence of Christ in the Eucharist became "real and compelling" to him (National Catholic Register).

How Catholics can walk with Baptists on the journey. Lessons drawn from these two stories:

• Be a faithful friend who knows the faith. Staples credits a fellow Marine, Matt, who stayed his friend through a year of debate and answered his questions with knowledge and love (Surprised by Truth excerpt; Catholic Answers).
• Accompany them through the hard part. Staples describes feeling alone on the verge of conversion; new candidates need companionship (Jimmy Swaggart Made Me Catholic).
• Listen patiently. Colleagues describe Staples helping people who struggle, "listening with patience and offering compassionate help" (Catholic Answers Magazine).
• Start from the Creed. Thompson points to the Creed as shared ground most Evangelicals affirm, with differences discussed from there (National Catholic Register).

• One baptism. Catholics and United Methodists recognize each other's baptisms. The eighth round of dialogue built on this "shared recognition of one another's baptisms" (Catholics and United Methodists Together).
• The Trinity and the Creed. Both profess the Apostles' Creed and pray the Lord's Prayer, the basis of the eighth round's shared commentaries (same source).
• Justification. In 2006 the World Methodist Council affirmed the Joint Declaration on the Doctrine of Justification, first signed by Catholics and Lutherans in 1999 (The Grace Given You in Jesus Christ, 2006).
• The Eucharist at the center. Both regard the Eucharist "as the central form of Christian worship" (USCCB, 2012).
• The Church as communion. The dialogue found "many parallels" in how both churches foster communion with God and one another (Through Divine Love, 2005; USCCB report).

As with the Baptists, these are noted here only in outline and will be treated in detail, with USCCB references, in the common section on differences. Unlike Baptists, Methodists baptize infants, so that is shared ground rather than a difference.

• The number of sacraments (Methodists recognize two: baptism and the Lord's Supper)
• The nature of Christ's presence in the Eucharist
• The authority of the Pope and the Magisterium
• Ordained ministry, including the ordination of women
• Mary and the saints

Catechism references. Grace and justification (Catechism 1987–2029); sanctification and the call to holiness (2012–2016); the Eucharist (1322–1419); Holy Orders and apostolic succession (861–862, 1536–1600); separated brethren (817–822, 838).

The same USCCB norms that apply to Baptists apply to Methodists. As baptized Christians they are "Candidates," received into full communion through a profession of faith, normally followed by Confirmation and first Eucharist, and are not baptized again (USCCB: Christian Initiation of Adults; USCCB: OCIA). Because Catholics and United Methodists formally recognize each other's baptisms, that common baptism is the starting point of formation (Catholics and United Methodists Together).

Guidance for OCIA leaders. The guidance in the Baptist section applies here as well: honor their baptism, fit formation to the person, and use the right rites. Many Methodists already know the liturgical year, the Creed, and a structured Communion service, so leaders can build on that familiarity.

Methodist converts face many of the same losses as Baptists: strained family ties, leaving a beloved congregation, and, for clergy, the loss of a career. Methodist pastors who convert often wrestle with what it means "for them, their families" and their livelihood; the Coming Home Network supports them through that transition (CHNetwork; Help for pastors). Catholics can respond the same way: a real parish family, lasting friendship, and encouragement to keep loving the Methodist family that first taught them Christ.

In the spirit of the "exchange of gifts" (Ut Unum Sint, 28), Methodists bring:

• A love of holiness. John Wesley's call to grow in holiness and Christian perfection resonates with the Catholic call to sanctity.
• Sacred song. The hymns of Charles Wesley are a treasure; some already appear in Catholic hymnals.
• Faith in action. Methodism's tradition of "social holiness" fits Catholic social teaching and works of mercy.
• Small-group discipleship. Wesley's class meetings model the accountability and fellowship that parishes seek.
• A love of the Eucharist and Scripture. The dialogue found both churches hold the Eucharist "as the central form of Christian worship" (USCCB, 2012).

Wesley himself wrote a Letter to a Roman Catholic (1749) urging mutual love across division, a fitting spirit for this whole apostolate.

Unlike the Baptists, Methodists sent official observers. Pope John XXIII invited the World Methodist Council to appoint delegates, including Bishop William Cannon and Prof. Albert Outler (Methodist Ecumenical Office Rome). Soon after the Council, Pope Paul VI invited the Methodists into a theological dialogue that has met continuously since, publishing 11 reports (same source).

A Methodist voice: Albert C. Outler. Outler, a theology professor at Southern Methodist University's Perkins School of Theology in Dallas, served as a delegate-observer at all four sessions of the Council, 1962–1965 (Texas State Historical Association). He met Pope Paul VI with the other observers on September 23, 1964 (MEOR). One account says Methodists welcomed the Council "with the enthusiasm of family members rediscovering their own place in a larger network of kinship and inheritance" (National Catholic Reporter). He assessed the Council in an essay titled "Charter for Change" (Paulist Fathers).

Book: Outler, Albert C. Methodist Observer at Vatican II (Internet Archive).

• Keith Nester, a pastor's kid and former Methodist pastor, told his story on EWTN's The Journey Home and now speaks about the help he received when he felt called to become Catholic (Journey Home; CHNetwork).
• Allan J. Cease came home to the Church "after 51 years as a Protestant and 28 years as a United Methodist clergyman" (A Methodist Pastor's Journey to Joy).
• Allen Hunt, a former United Methodist megachurch pastor, wrote Confessions of a Mega-Church Pastor about his conversion (video).

• Justification. On October 31, 1999, in Augsburg, the Catholic Church and the Lutheran World Federation signed the Joint Declaration on the Doctrine of Justification. Its heart, paragraph 15: "Together we confess: By grace alone, in faith in Christ's saving work and not because of any merit on our part, we are accepted by God and receive the Holy Spirit, who renews our hearts while equipping and calling us to good works" (Joint Declaration; First Things). The sixteenth-century condemnations on this point "do not apply to today's partner" (Joint Declaration, 13).
• The Trinity and the Creeds. Both profess the Apostles' and Nicene Creeds.
• Infant baptism. Like Catholics, Lutherans baptize infants and recognize one baptism.
• Liturgy. Lutheran worship follows the liturgical year and a structured Mass-like service.
• Christ's real presence in the Eucharist. Lutherans affirm that Christ is truly present in the Lord's Supper, though they explain it differently.

Noted in outline only; detail will come in the common section on differences.

• The authority of the Pope and the Magisterium
• How Christ is present in the Eucharist (Lutherans do not hold transubstantiation)
• The number of sacraments
• Ordained ministry, including the ordination of women in some Lutheran bodies
• Mary and the saints, purgatory, and prayers for the dead

Catechism references. Justification (Catechism 1987–1995); grace and merit (1996–2011); the Real Presence (1373–1381); the Mass as sacrifice (1362–1367); the Pope and bishops (880–896); separated brethren (817–822, 838).

The same USCCB norms apply: Lutherans are baptized "Candidates," received through a profession of faith, normally followed by Confirmation and first Eucharist (USCCB: Christian Initiation of Adults). Their familiarity with liturgy, creeds, and the sacraments often means a shorter, tailored formation.

Guidance for OCIA leaders. The guidance in the Baptist section applies: honor their baptism, fit formation to the person, and use the right rites. With Lutherans, leaders can begin from the Joint Declaration's shared confession of grace.

Lutheran converts face familiar losses. One convert recalled that she could not explain her journey to her "horrified Protestant family and friends" (More Than Enough). A Lutheran pastor and district dean of 34 years described becoming Catholic late in his ministry (Aleteia). Catholics should offer the same lasting parish family and patient friendship.

• A deep grasp of grace. Their emphasis on God's free gift echoes the Joint Declaration's shared confession.
• Sacred music. The Lutheran chorale tradition, including the music of J. S. Bach, enriches Catholic worship.
• Love of Scripture and preaching. Lutherans prize the proclaimed Word.
• Liturgical and catechetical tradition. Many know the creeds and catechism well, a ready foundation for Catholic formation.

Like the Methodists, Lutherans sent official observers, appointed by the Lutheran World Federation. Among them was Yale theologian George Lindbeck, one of the LWF's three delegated observers, who served from 1962 through 1965. He recalled being "the junior member of the Lutheran delegation" and "the only one assigned full-time to Council business between the sessions" (First Things, 1994 interview with George Weigel). From 1968 to 1987 he served on the Joint Commission between the Vatican and the Lutheran World Federation (Wikipedia). The dialogue that began after the Council led directly to the 1999 Joint Declaration (Lutheran World Federation).

Lund, 2016. On October 31, 2016, Pope Francis joined Lutheran leaders for a common prayer service in Lund Cathedral in Sweden, launching the 500th anniversary of the Reformation. It was the first time a Pope had taken part in a Reformation commemoration. In his homily, Francis acknowledged with gratitude that "the Reformation helped give greater centrality to sacred Scripture in the Church's life" (Vatican). He and Bishop Munib Younan, president of the Lutheran World Federation, signed a joint statement committing to keep working toward full unity, and spoke of the pain of families who "cannot share God's redeeming presence at the Eucharistic table" (Joint Statement).

• Paul Abbe served as a Lutheran pastor for over 12 years and was received into full communion in September 2006 "after a long journey of prayer, study and struggle" (Journey Home).
• David Woodby, a former Lutheran pastor, was "continually troubled by the question of disunity among Christians" (Journey Home).
• Billy Kangas, raised Lutheran (Missouri Synod), wrestled with papal authority before coming home, and has written about discovering the Rosary (CHNetwork).

• A passion for Christian unity. Founder Thomas Campbell wrote in 1809 that "division among Christians is a horrid evil" and that "the church of Christ upon earth is essentially, intentionally and constitutionally one" (Disciples of Christ: A Brief Description, prepared for the Disciples–Catholic dialogue). Catholics share this longing for one visible Church.
• The Lord's Supper every Sunday. Weekly communion is central to Churches of Christ, as the Eucharist is to Catholic Sunday worship. Alexander Campbell wrote, "In the house of God there is always the table of the Lord" (John Mark Hicks, Disciples CUIM). The Disciples–Catholic dialogue noted the movement's desire for "a unity rooted in the weekly celebration of the Lord's Supper" (same Vatican source as above).
• Baptism matters for salvation. Churches of Christ teach that baptism is part of how we are saved, not merely a symbol. This is much closer to Catholic teaching than the Baptist view.
• Faith and obedience together. Like Catholics, Churches of Christ reject "faith alone" as a stand-alone formula, citing James 2:24.
• Love of Scripture and the early Church. Both look to the apostolic Church as the model for faith and practice.

Noted in outline only; detail will come in the common section on differences.

• Scripture alone versus Scripture and Sacred Tradition
• Believer's baptism by immersion only, so no infant baptism
• The authority of the Pope, bishops, and the Magisterium (each congregation is self-governing)
• How Christ is present in the Lord's Supper
• A cappella worship only, without instruments, and no liturgical calendar
• Mary and the saints

Catechism references. Baptism and its necessity (Catechism 1213–1284, esp. 1257); infant baptism (1250–1252); the Eucharist and Sunday worship (1322–1419, 2177–2179); Scripture and Tradition (74–141); the Church's structure and apostolic succession (857–896); separated brethren (817–822, 838).

The same USCCB norms apply: baptized Christians are "Candidates," received through a profession of faith, normally followed by Confirmation and first Eucharist (USCCB: Christian Initiation of Adults). Baptism by immersion in the name of the Trinity is valid and is never repeated. Their deep Bible knowledge is a gift; formation can show how Catholic teaching grows from the Scriptures they already love.

Guidance for OCIA leaders. Begin from shared ground: weekly communion, the importance of baptism, and the call to unity. Be ready to discuss instrumental music and the liturgy patiently, since worship will feel very different.

Because Churches of Christ have often taught that they alone are the restored New Testament church, a member who becomes Catholic may face deep grief from family and congregation. Catholics should offer patient friendship and a true parish family.

• Deep knowledge of Scripture. Many can quote chapter and verse.
• Weekly devotion to the Lord's Supper. A ready love for the Eucharist.
• A cappella singing. A rich tradition of congregational harmony.
• A heart for unity. The founders' longing for one Church echoes Christ's prayer "that they may all be one" (John 17:21).

Churches of Christ sent no observers, since they have no central body to appoint them. Their sister body did: the World Convention of Churches of Christ (Disciples) named Dr. Jesse M. Bader as its delegate-observer in 1962 (Christianity Today, 1962), and Dr. W. B. Blakemore of the University of Chicago's Disciples Divinity House served in later sessions (Christianity Today, 1965). The Disciples later entered a formal international dialogue with the Catholic Church in 1977.

• A Churches of Christ voice: John Mark Hicks. A theologian from the Churches of Christ who teaches at Lipscomb University, Hicks writes on the Lord's Supper, Christian unity, and the Stone-Campbell heritage. He openly draws on Catholic and other traditions in imagining the future of Churches of Christ (Discipleship in Community, with Mark Powell and Greg McKinzie, ACU Press 2020; johnmarkhicks.com). No Churches of Christ scholar is known to have written on Vatican II itself.

• The Coming Home Network keeps a collection of Church of Christ conversion stories ([CHNetwork](https://chnetwork.org/converts/churchofchrist/)). One convert wrote that the Churches of Christ "showed me — from the Bible — that Baptism is for the remission of sins" and that justification "is not by faith alone," calling them "a stepping-stone" to the Catholic faith (same source). Rachelle Parker, raised in a large Churches of Christ congregation in Springfield, Missouri, describes weekly communion and baptism for forgiveness as the roots of her journey; she also told her story on EWTN's The Journey Home ([From the Churches of Christ to the One Church](https://chnetwork.org/story/churches-christ-one-church/)). The first quoted story is unsigned on the site, so it is cited without a name.

• One baptism. In 2010 the US bishops and the PC(USA) signed the Common Agreement on Mutual Recognition of Baptism. It recognizes baptisms performed "with flowing water in the name of the Father and of the Son and of the Holy Spirit" (USCCB, Common Agreement; These Living Waters).
• Infant baptism. Like Catholics, Presbyterians baptize infants as a sign of God's covenant grace.
• The Creeds and the Trinity. Both confess the Apostles' and Nicene Creeds.
• The primacy of grace. Both teach that salvation begins with God's initiative, not ours.
• The Lord's Supper as a real encounter with Christ. The 2012 dialogue report This Bread of Life explored deep common ground on the Eucharist (USCCB).
• Love of Scripture and ordered worship.

• Authority: governance by elders and councils rather than bishops in apostolic succession and the pope.
• Eucharist: Calvin taught a real but spiritual presence of Christ, not transubstantiation.
• Sacraments: two (Baptism and the Lord's Supper) rather than seven.
• Ordination: including women as ministers and elders.
• Mary and the saints: no prayer to the saints or Marian dogmas.

Detail on these is reserved for the shared section on common differences.

Catechism references. Predestination and God's eternal plan (Catechism 600); grace and free will (1730–1742, 1993, 2022); the sacraments (1113–1134); Holy Orders and bishops (1536–1600, 880–896); the Real Presence (1373–1381); separated brethren (817–822, 838).

Because their baptism is recognized as valid, Presbyterians are not rebaptized. Under the USCCB's National Statutes for the Catechumenate, they are prepared as baptized candidates and received through a profession of faith, Confirmation, and First Communion. They are not treated as catechumens.

For Presbyterian ministers, coming in can mean giving up a pulpit, a salary, and a pastoral identity. For laypeople, it can mean strain with family and a congregation that has been home for generations.

• Deep knowledge of Scripture and a love of preaching.
• A tradition of singing the Psalms.
• Catechetical seriousness. The Westminster Shorter Catechism's first answer, "Man's chief end is to glorify God, and to enjoy him forever," is one any Catholic can say.
• A gift for order, education, and service to the common good.

The World Presbyterian Alliance sent official delegate-observers: Dr. James H. Nichols of Princeton Theological Seminary, the Rev. Hébert Roux of France, and the Rev. Douglas Shaw (Christianity Today, 1962).

Featured voice: Robert McAfee Brown. A Presbyterian theologian, Brown served as an official observer for the World Alliance of Reformed and Presbyterian Churches (Online Archive of California, Brown Collection) and wrote Observer in Rome (1964), a warm and candid diary of the Council. He became one of the leading American Protestant voices for Catholic–Protestant friendship after Vatican II.

• Scott Hahn, a former Presbyterian minister, tells his story in Rome Sweet Home (with his wife Kimberly). His study of the covenant, a central Presbyterian theme, led him to the Catholic Church.
• Marcus Grodi, a former Presbyterian pastor, founded the Coming Home Network and hosts EWTN's The Journey Home.

• Bishops and the threefold ministry of bishops, priests, and deacons.
• Liturgical worship. The Book of Common Prayer closely follows the shape of the Mass, the Church year, and the Daily Office.
• Baptism, including infant baptism, is mutually recognized.
• The Creeds and the early Church Fathers.
• Sacramental life. Many Episcopalians practice confession, anointing, and devotion to the Real Presence.

• Papal authority: no recognition of the Pope's universal jurisdiction.
• Holy Orders: In 1896 Pope Leo XIII's Apostolicae Curae judged Anglican ordinations invalid, so Anglican clergy who become Catholic priests are ordained.
• Ordination of women, including as bishops.
• Moral teaching on marriage and sexuality.
• Mary and the saints: devotion varies widely, and Marian dogmas are not binding.

Detail is reserved for the shared section on common differences.

Catechism references. Holy Orders and apostolic succession (Catechism 861–862, 1536–1600); ordination reserved to men (1577–1578); the Pope's ministry of unity (880–896); marriage (1601–1666); the Eucharist (1322–1419); separated brethren (817–822, 838).

Episcopalians are received as baptized candidates through a profession of faith, Confirmation, and First Communion. They also have a path unique among Protestants. Pope Benedict XVI's Anglicanorum Coetibus (2009) created Personal Ordinariates, and the American one, the Personal Ordinariate of the Chair of Saint Peter, is based in Houston. It lets former Anglicans enter full communion while keeping parts of their liturgy and spiritual heritage in the approved Divine Worship missal.

Clergy may lose their parish and income, and married clergy face the long process of seeking ordination as Catholic priests. Laypeople may grieve the beloved prayer book language and parish communities they leave behind, though the Ordinariate softens that loss.

• The beauty of the Book of Common Prayer and English choral music.
• A rich sense of liturgy, reverence, and the Church year.
• The Anglican gift for patient theology and a love of the Fathers.

The Archbishop of Canterbury appointed Anglican delegate-observers, including Bishop John Moorman of Ripon and Dr. Frederick C. Grant, an American Episcopal scholar (Christianity Today, 1962). Later sessions added Canon Clement W. Welsh of Washington National Cathedral and Peter F. Day of the Episcopal Church's Executive Council (Christianity Today, 1965). The Decree on Ecumenism singled out the Anglican Communion as holding "a special place" among communions where Catholic traditions continue (Unitatis Redintegratio 13).

Featured voice: Frederick C. Grant. Grant was a New Testament scholar at Union Theological Seminary and served as an Anglican observer in 1962–1963 (Episcopal Church glossary, "Grant, Frederick Clifton"). He brought the American Episcopal perspective into the Council's discussions of Scripture and liturgy.

• Jeffrey Steenson, former Episcopal Bishop of the Rio Grande, became Catholic and served as the first Ordinary of the Chair of Saint Peter.
• St. John Henry Newman, though English and Anglican, is the patron of this path. His Apologia Pro Vita Sua remains the classic account.

• Life in the Holy Spirit. Since the 1967 Duquesne Weekend, the Catholic Charismatic Renewal has brought Pentecostal-style prayer, praise, and the charisms into Catholic parishes worldwide.
• Belief in miracles and healing and a living, active God.
• The Trinity and the divinity of Christ (for Trinitarian Pentecostals).
• Personal conversion and evangelization. These echo the Church's call to a personal encounter with Christ and a New Evangelization.
• Moral convictions on life, marriage, and family.

• Authority: Scripture and the Spirit's leading rather than the Magisterium and apostolic succession.
• Sacraments: baptism and the Lord's Supper as ordinances, usually understood symbolically.
• Baptism: believer's baptism by immersion, not infants.
• Mary and the saints: generally rejected as unbiblical devotion.
• Church structure: often independent or loosely federated congregations.

Detail is reserved for the shared section on common differences.

Catechism references. The Holy Spirit (Catechism 683–747); charisms and their discernment (799–801, 2003); Confirmation (1285–1321); Scripture and Tradition (74–141); the Trinity, relevant to Oneness Pentecostals (232–267); separated brethren (817–822, 838).

Most Pentecostals are baptized with water in the name of the Trinity, so they are received as baptized candidates. Important caution: Oneness Pentecostals (such as the United Pentecostal Church International) baptize "in Jesus' name" only and deny the Trinity, so their baptisms are not recognized as valid. Those candidates are baptized when they enter. Parish OCIA teams should always ask about the form of baptism.

Former Pentecostals often miss the spontaneity, expressive worship, and close-knit fellowship of their congregations. Pastors may lose their church and livelihood, and family members may view the move as leaving true faith behind.

• Bold, expectant prayer and openness to the Holy Spirit.
• Joyful, wholehearted praise.
• Evangelistic zeal and ease in sharing personal testimony.
• A deep love for Scripture.

Featured voice: David du Plessis. A South African Pentecostal minister known as "Mr. Pentecost," du Plessis attended the third session of the Council as a guest of the Secretariat for Promoting Christian Unity (Dicastery for Promoting Christian Unity, 2022 news release). His friendships with Catholic leaders led directly to the 1972 dialogue, which he co-chaired with Benedictine Fr. Kilian McDonnell. More recently, Pope Francis visited a Pentecostal church in Caserta, Italy, in 2014 and asked forgiveness for Catholics who had persecuted Pentecostals.

• Alex Jones, a Detroit Pentecostal pastor, entered the Catholic Church in 2001 together with members of his congregation. He was ordained a permanent deacon for the Archdiocese of Detroit in 2005 and died in 2017 (Detroit Catholic). His story is told in No Price Too High.

• A call to peacemaking. Mennonite nonviolence resonates with Catholic teaching on peace and the Church's growing caution about war.
• Discipleship and holiness of life. Following Jesus in daily life echoes the Catholic call to holiness.
• Simplicity and community. These recall Catholic religious life and its vows.
• Service to the poor. Mennonite Central Committee and Catholic Relief Services often work side by side.
• The Creeds and the Trinity.

• Baptism: believer's baptism only, not infants.
• Authority: the gathered congregation discerning Scripture, rather than the Magisterium and apostolic succession.
• Sacraments: baptism and the Lord's Supper as ordinances, often with foot washing.
• Church and state: some reject oaths, military service, or public office.
• Mary and the saints.

Detail is reserved for the shared section on common differences.

Catechism references. Peace and the avoidance of war (Catechism 2302–2317); conscientious objection (2311); infant baptism (1250–1252); the Church and civil authority (2238–2243); the Eucharist (1322–1419); separated brethren (817–822, 838).

Mennonite baptisms done with water in the name of the Trinity are generally recognized, so Mennonites are received as baptized candidates. Parish OCIA teams should confirm the form used.

Mennonite identity is often ethnic and familial as well as religious. Leaving can feel like leaving a people, not just a church. The memory of persecution can also make the move emotionally heavy for family members.

• A deep witness to peace and reconciliation.
• Practiced simplicity and generous service.
• Strong community and mutual care.
• Beautiful four-part a cappella hymn singing.

No Mennonite observers appear in the published observer lists. The first formal contact came later: Pope John Paul II invited the Mennonite World Conference to the 1986 Assisi Day of Prayer for Peace (Called Together to Be Peacemakers, Dicastery for Promoting Christian Unity). The Council's teaching on peace in Gaudium et Spes (77–82) and its respect for conscientious objection (79) touched convictions Mennonites had held for 400 years.

• Harold Wenger, a cradle Mennonite, was confirmed and received his first Communion at Holy Cross Catholic Church in Mesa, Arizona, on May 1, 2011 (CHNetwork).
• Dr. Ryan Topping, raised Mennonite in Canada and active in youth ministry, was led to the Catholic Church in part by a dispute in his congregation over baptism. He is now a Catholic scholar and author (The Journey Home).

• Jesus Christ as Lord and Savior, and a call to a personal relationship with him.
• The Trinity and the Creeds, even where Creeds are not recited in worship.
• Love of Scripture as the inspired Word of God.
• Evangelization. Their zeal matches the Church's call to a New Evangelization.
• Moral convictions on the dignity of life, marriage, and religious liberty. On these issues Catholics and evangelicals often stand together in public life.

• Authority: the Bible alone, often interpreted by each believer or pastor, rather than Scripture, Tradition, and the Magisterium.
• Church: the Church as an invisible fellowship of believers, not a visible, sacramental, apostolic body.
• Sacraments: baptism and communion as symbols or ordinances; communion is often monthly or quarterly.
• Baptism: usually believer's baptism, not infants.
• Salvation: often framed as a single moment of decision ("once saved, always saved" in some churches).
• Mary and the saints.

Detail is reserved for the shared section on common differences.

Catechism references. Scripture and Tradition (Catechism 74–141); the Church as visible and sacramental (770–776); the sacraments (1113–1134); infant baptism (1250–1252); justification and perseverance (1987–2029); evangelization and mission (849–856); separated brethren (817–822, 838).

Because practices vary from church to church, parish OCIA teams must ask each candidate how they were baptized. A baptism with water in the name of the Father, Son, and Holy Spirit is valid, and the person is received as a baptized candidate. If the form is doubtful or unknown, a conditional baptism may be done.

Evangelical converts often hear that they have "left Christ" for rituals and works. That can strain friendships and family. Many also miss the casual worship style, the music, and the small-group closeness of their former churches.

• A personal, conversational relationship with Jesus.
• Familiarity with Scripture and a habit of daily Bible reading.
• Comfort sharing their faith with others.
• Vibrant worship music and a spirit of welcome.

Nondenominational churches did not exist as an organized movement at the time of the Council and sent no observers. Evangelical publications such as Christianity Today covered the Council closely (Christianity Today, 1965), and the Council's call to read Scripture (Dei Verbum 22–25) opened new common ground with Bible-centered Christians.

• Francis J. Beckwith. A Baylor philosopher and president of the Evangelical Theological Society, he returned to the Catholic Church in May 2007 and resigned the presidency a week later (Christian Century, 2007). He tells the story in Return to Rome: Confessions of an Evangelical Catholic (2009), crediting the Church Fathers and Aquinas.
• Thomas Howard. An evangelical writer, Gordon College professor, and brother of missionary Elisabeth Elliot, he became Episcopalian in his mid-twenties, described his path in Evangelical Is Not Enough (1984), and was received into the Catholic Church in 1985 at age 50 (Christianity Today, 1985). His sister said he was fully aware of what the move might cost him and was prepared to pay the price.

The North American Orthodox-Catholic Theological Consultation, co-sponsored by the USCCB and Orthodox bishops, was established in 1965, and the international Joint Commission in 1979 (USCCB Orthodox). Its best-known statement is The Filioque: A Church-Dividing Issue? (October 25, 2003), which recommended ways to heal the oldest doctrinal dispute between East and West (USCCB).

Almost everything: the Trinity and the Nicene Creed; the seven sacraments, all of them valid; bishops in apostolic succession and a valid priesthood; the Real Presence of Christ in the Eucharist; deep love for Mary, the Mother of God (Theotokos), and the saints; icons, the first seven ecumenical councils, the Church Fathers, monastic life, and fasting. The Catechism says the Orthodox churches are joined to us in "so profound" a communion "that it lacks little to attain the fullness that would permit a common celebration of the Lord's Eucharist" (Catechism 838; Unitatis Redintegratio 15).

• The papacy. The Orthodox honor the Bishop of Rome as historically "first among equals" but do not accept his universal jurisdiction or infallibility.
• The Filioque. The Western Creed says the Holy Spirit proceeds "from the Father and the Son"; the Orthodox say "from the Father."
• Later Western teachings. The Orthodox do not accept as dogma the Immaculate Conception (1854) or purgatory as defined in the West, though they pray for the dead and honor Mary as all-holy.
• Practice. Married men may be ordained priests (as in Eastern Catholic Churches); infants receive baptism, chrismation, and Communion together; the date of Easter often differs.

Catechism 838 (communion with the Orthodox), 1399 (Eucharist with the Eastern churches), 246–248 (the Filioque), 882 (papal primacy).

• Jerusalem, 1964. Pope St. Paul VI and Ecumenical Patriarch Athenagoras embraced, the first meeting of pope and patriarch in centuries.
• December 7, 1965. The two lifted the mutual excommunications of 1054.
• "Two lungs." St. John Paul II said the Church must "breathe with her two lungs," East and West (Ut Unum Sint 54).
• Pope Francis and Patriarch Bartholomew met often, including in Jerusalem in 2014, and Francis met Patriarch Kirill of Moscow in Havana in 2016. On November 28, 2025, Pope Leo XIV and Patriarch Bartholomew prayed together at İznik (ancient Nicaea), Türkiye, for the 1,700th anniversary of the Council of Nicaea, and signed a joint declaration the next day (Vatican).

Because Orthodox sacraments are valid, the Catholic Church permits Catholics, when they cannot reach a Catholic priest, to receive Penance, Eucharist, and Anointing from an Orthodox priest, and allows Orthodox Christians to receive them from Catholic priests if they ask on their own and are properly disposed (Catechism 1399; Code of Canon Law 844). Catholics should respect that most Orthodox churches do not permit this, and should not approach for Communion at an Orthodox liturgy without the priest's blessing.

An Orthodox Christian becoming Catholic is not baptized or confirmed again; their baptism and chrismation are fully valid. They make a simple profession of faith and are received, normally into the Eastern Catholic Church of their own tradition (such as Byzantine or Ukrainian Catholic), though they may later seek to transfer to the Latin Church (Code of Canons of the Eastern Churches 35; Canon Law 112). They do not belong in the full OCIA process for the unbaptized.

The Divine Liturgy of St. John Chrysostom, icons, the Jesus Prayer, deep traditions of fasting, the Church Fathers, and a sense of worship as heaven on earth, a gift the whole Church needs.

On June 5, 2001, the Congregation for the Doctrine of the Faith ruled that baptism conferred by the Latter-day Saints "cannot be considered a valid Christian baptism" (Vatican). In an accompanying explanation, Fr. Luis Ladaria, S.J., noted that doctrinal error alone does not normally invalidate baptism, but that the Latter-day Saint understanding of Father, Son, and Holy Spirit differs so deeply that the words do not mean the Trinity (Vatican). Relations have nevertheless grown warmer: in 2010 Cardinal Francis George of Chicago spoke at Brigham Young University (BYU Religious Studies Center).

• Love for Jesus Christ, whom they worship as Savior and Son of God, and devotion to the Bible.
• Strong family life, marriage, and care for children.
• Defense of religious liberty and the dignity of life.
• Service and charity: both run large humanitarian and disaster-relief efforts.
• Moral discipline: fasting, modesty, and avoiding alcohol and other harmful habits.

• God. Latter-day Saints believe the Father, Son, and Holy Spirit are three separate beings, and that God the Father has a glorified body. Catholics believe in one God in three Persons (Catechism 253–255).
• Scripture. Besides the Bible, they accept the Book of Mormon, the Doctrine and Covenants, and the Pearl of Great Price, and believe in continuing revelation through a living prophet.
• Authority. They believe the priesthood was lost after the apostles and restored through Joseph Smith; Catholics believe it has continued in apostolic succession (Catechism 861–862).
• Salvation and the afterlife. They teach eternal progression, degrees of glory, and baptism for the dead in their temples.

• Use the name they prefer, and never mock their temple garments or beliefs.
• Welcome missionaries kindly: offer water, listen, and share your own faith honestly.
• Work together on service, food banks, and disaster relief.
• Talk about Jesus first; explain the Trinity patiently as the heart of our faith.

Because their baptism is not recognized, a Latter-day Saint becoming Catholic enters through the full OCIA process and receives baptism, confirmation, and the Eucharist, usually at the Easter Vigil. Their love of family, service, and discipline is a gift they bring.

• Family Home Evening: one night a week set apart for family prayer, a short lesson, and fun together.
• Missionary zeal: young people giving two years to share their faith.
• Fast offerings: fasting once a month and giving the money saved to the poor, much like the Catholic tradition of Lenten almsgiving.
• Caring for one another: organized ministering to every family in the congregation.

• Deep respect for the Bible and love of studying it.
• Belief in God as Creator and in Jesus as Savior through his sacrifice.
• Moral seriousness, strong families, and courage: Witnesses were persecuted under the Nazis and sent to the camps for refusing to serve the regime.

• God and Jesus. Witnesses reject the Trinity. They worship Jehovah alone, believe Jesus is God's first creation (identified with the archangel Michael), and see the Holy Spirit as God's active force, not a Person. Catholics profess Jesus as true God and true man (Catechism 464–469).
• Scripture. They use their own translation, the New World Translation, which renders John 1:1 "the Word was a god."
• The end times and the afterlife. They teach that 144,000 will reign in heaven and others will live forever on a restored earth; they do not believe in an immortal soul or eternal hell.
• Practice. They celebrate only the yearly Memorial of Christ's death, and do not celebrate Christmas, Easter, or birthdays, salute flags, or vote. They refuse blood transfusions.
• Baptism. Because their baptism is not given in the name of the Trinity as the Church understands it, Catholic dioceses list Witness baptism as invalid, and former Witnesses are baptized when they become Catholic. The Diocese of San Diego lists Jehovah's Witnesses among invalid baptisms, citing Huels, The Pastoral Companion (Diocese of San Diego), and the Diocese of Columbus explains that Witness "baptism" is a symbol of dedication with no words or formula pronounced (Diocese of Columbus).

• When Witnesses come to the door, be kind and patient; they are acting from conviction.
• Know your faith: be ready to show from Scripture why Christians believe Jesus is God (John 1:1, John 20:28, Philippians 2:5–11).
• Respect their conscience on holidays and blood while gently sharing your own beliefs.
• Former Witnesses who leave sometimes lose contact with family and friends. Catholics can offer them welcome and patience.

Like former Latter-day Saints, former Witnesses come through the full OCIA process and are baptized. Many need time to heal and to learn to trust a church again; they bring with them a love of Scripture.

• Knowing Scripture well, and being able to find and explain passages.
• Courage in sharing faith with strangers.
• Weekly study and training in how to explain one's beliefs.

What Catholics believe. Everything the Church teaches about Mary begins and ends with Jesus. She is loved because of who her Son is, and every Marian teaching is meant to protect a truth about him or about the grace he offers to all of us. Many Protestant friends already share more of this than they may realize.

• Mother of God. The Council of Ephesus (431) called Mary Theotokos, "God-bearer," not to raise Mary up but to confess that the child she bore is truly God (Catechism 495). Elizabeth said it first: "the mother of my Lord" (Luke 1:43). Many Protestant traditions accept this ancient council.
• Ever-Virgin. Catholics believe Mary remained a virgin throughout her life, wholly given to God's plan (Catechism 499–501). The "brothers" of Jesus are understood as close relatives, as the word could mean in that culture. Reformers such as Martin Luther and Ulrich Zwingli held this belief too.
• Immaculate Conception. Defined in 1854 (Ineffabilis Deus), it teaches that Mary was preserved from original sin from her conception (Catechism 490–493). This is pure grace, not her own merit: she was saved by Christ, in anticipation of his cross. The angel greets her as "full of grace" (Luke 1:28), and Mary herself rejoices in "God my Savior" (Luke 1:47).
• Assumption. Defined in 1950 (Munificentissimus Deus), it teaches that Mary was taken body and soul into heavenly glory (Catechism 966). Catholics see in her a sign of the resurrection Christ promises to every believer.
• Mother of the Church. From the cross Jesus gave Mary to the beloved disciple: "Behold, your mother" (John 19:26–27). Catholics hear in this a gift to every disciple. Her last recorded words, at Cana, sum up her whole role: "Do whatever he tells you" (John 2:5).
• Intercessor, never rival. Mary's prayer for us flows from Christ's one mediation and depends entirely on it (Lumen Gentium 60–62; Catechism 969–970).
• Honor, not worship. Catholics worship God alone. Mary and the saints receive honor (veneration), much as we honor a beloved mother, and that honor is always meant to lead to her Son (Catechism 971).

The saints are part of the same family. Asking a saint to pray for us is like asking a friend to pray for us, rooted in the communion of saints (Catechism 956).

What the U.S. bishops teach. In their 1973 pastoral letter Behold Your Mother: Woman of Faith, the U.S. bishops (then the National Conference of Catholic Bishops, now the USCCB) presented Mary as a woman of faith and model disciple, rooted in Scripture and always pointing to Christ. The letter, along with other Church teaching on Mary, is collected in the USCCB's Mary in the Church: A Collection of Teaching Documents (2003). The USCCB's United States Catholic Catechism for Adults also gives a chapter to Mary as the Church's first and greatest disciple. It is Chapter 12, "Mary: The Church's First and Most Perfect Member" (USCCB).

What Protestants usually believe. Christ is the "one mediator between God and men" (1 Timothy 2:5). Praying to saints or honoring Mary can seem to take glory from Christ. Many also question doctrines such as the Immaculate Conception and Assumption because they are not stated directly in Scripture.

Common ground from the dialogues.

• The U.S. Lutheran–Catholic Dialogue, The One Mediator, the Saints, and Mary (Round VIII, common statement 1990, published 1992; USCCB list of rounds), agreed that Christ alone is mediator and that the saints' prayer depends wholly on him.
• The Anglican–Roman Catholic International Commission, Mary: Grace and Hope in Christ (2005), concluded that Anglicans and Catholics are in substantial agreement in their faith about Mary (Dicastery for Promoting Christian Unity commentary).
• Nearly all Christians share the Creed's confession that Jesus was "born of the Virgin Mary," and many Protestant reformers, including Luther, held Mary in high regard.

Sources that speak to Protestant friends.

• Mary in Scripture. The angel calls her "full of grace" (Luke 1:28); Elizabeth, filled with the Holy Spirit, cries out, "Blessed are you among women" (Luke 1:42); and Mary foretells, "all generations will call me blessed" (Luke 1:48). She is present at Cana, at the cross, and with the apostles at Pentecost (John 2:1–11; John 19:25–27; Acts 1:14).
• The saints in Scripture. Hebrews describes believers surrounded by "so great a cloud of witnesses" (Hebrews 12:1), and Revelation shows the saints in heaven offering "the prayers of the holy ones" before God (Revelation 5:8).
• The early Church. St. Irenaeus of Lyons (around AD 180) called Mary the "new Eve": as Eve's disobedience brought death, Mary's "yes" opened the way to the Savior: "the knot of Eve's disobedience was loosed by the obedience of Mary" (Against Heresies 3.22.4; New Advent).
• Martin Luther. Luther's Commentary on the Magnificat (1521) is a warm meditation on Mary as a model of humble faith, and many Lutherans still read it (La Civiltà Cattolica).
• An evangelical voice. Scot McKnight's The Real Mary: Why Evangelical Christians Can Embrace the Mother of Jesus (2007, Paraclete Press) invites evangelicals to rediscover Mary through the Bible.

How to explain it with love. Start in Scripture: Mary's own words, "all generations will call me blessed" (Luke 1:48), and the Bible's call to pray for one another (James 5:16). Make clear that honoring Mary always points to her Son. Avoid making Marian devotion a test of a newcomer's faith; let it grow naturally.

What Catholics believe. The Pope's ministry is first a ministry of unity and service. Catholics hold that Christ entrusted a special role to Peter and that it continues in his successors, the bishops of Rome. One of the Pope's oldest titles says it well: "servant of the servants of God."

• Rooted in Peter. Jesus named Simon "Rock" and gave him the keys of the kingdom (Matthew 16:18–19), asked him to strengthen his brothers (Luke 22:32), and told him three times, "Feed my sheep" (John 21:15–17). The Catechism teaches that this role continues in the Pope as a "perpetual and visible source and foundation of unity" (Catechism 881–882; Lumen Gentium 18–23).
• With the bishops, not apart from them. The Pope serves together with all the bishops as one college, as Peter served with the apostles (Catechism 880, 883–887).
• Infallibility, rightly understood. Infallibility does not mean the Pope is sinless or that everything he says is free from error. It is a rare protection, used only when he solemnly defines a teaching on faith or morals for the whole Church (Catechism 889–891; Vatican I, Pastor Aeternus, 1870). It has been formally used only a handful of times, such as the two Marian definitions of 1854 and 1950.
• What the U.S. bishops teach. The USCCB's United States Catholic Catechism for Adults presents the Pope and bishops as servants who guard the faith handed down from the apostles.

What Protestants usually believe. Christ alone is head of the Church, and Scripture is its final authority. Most Protestants read Matthew 16 as referring to Peter's confession of faith, not to an office passed down. Many also worry that papal power can stand between believers and Christ.

Common ground from the dialogues.

• The U.S. Lutheran–Catholic Dialogue, Papal Primacy and the Universal Church (Round V, 1974), found that Lutherans could see value in a ministry serving the unity of the whole Church, if it is renewed under the Gospel. Round VI, Teaching Authority and Infallibility in the Church (common statement 1978, published 1980), continued that work (USCCB list of rounds).
• The Anglican–Roman Catholic International Commission's The Gift of Authority (1999) recommended that Anglicans be open to a "re-reception" of universal primacy exercised by the Bishop of Rome, and proposed shared steps even before full communion (IARCCUM text; USCCB response).
• In Ut Unum Sint (1995, nos. 95–96), St. John Paul II humbly invited other Christians to help him find a way of exercising papal primacy that could serve all. The Vatican's 2024 study document The Bishop of Rome (June 2024) gathered the responses (Dicastery for Promoting Christian Unity; USCCB).

How to explain it with love. Begin with what we share: Christ is the head of the Church, and the Pope is his servant, not his rival. Point to the Pope as a gift for unity in a divided Christian world, and to recent Popes who have asked forgiveness for past failures. Acknowledge honestly that the papacy has been a real stumbling block, and that John Paul II himself said so.

What Catholics believe. The Eucharist is "the source and summit of the Christian life" (Catechism 1324; Lumen Gentium 11). Catholics believe that in it Jesus gives us himself, as he promised.

• Truly present. Christ is present in the Eucharist "truly, really, and substantially," body and blood, soul and divinity (Catechism 1374). Catholics take Jesus at his word: "This is my body" (Matthew 26:26) and "my flesh is true food" (John 6:55).
• Transubstantiation. The Church uses this word, affirmed at the Council of Trent, to say that the bread and wine become Christ's body and blood while still looking and tasting like bread and wine (Catechism 1376). It names the mystery; it does not explain it away.
• One sacrifice made present. The Mass does not repeat or add to Calvary. It makes present the one sacrifice of Christ, offered once for all (Catechism 1362–1367; Hebrews 10:10).
• What the U.S. bishops teach. The USCCB's The Real Presence of Jesus Christ in the Sacrament of the Eucharist: Basic Questions and Answers (2001) answers common questions in plain language. Their 2021 document The Mystery of the Eucharist in the Life of the Church launched the National Eucharistic Revival (2022–2025).

What Protestants usually believe. Views differ widely. Lutherans affirm Christ's true bodily presence "in, with, and under" the bread and wine, but reject transubstantiation. Presbyterians and other Reformed Christians teach a real spiritual presence received by faith. Baptists, Churches of Christ, and most evangelicals see the Lord's Supper as a memorial of Christ's death. Many Protestants object that the Mass seems to re-sacrifice Christ.

Common ground from the dialogues.

• The U.S. Lutheran–Catholic Dialogue, The Eucharist as Sacrifice (Round III, 1967; USCCB list of rounds), found major agreement on Christ's real presence and on the Mass as a memorial that makes his one sacrifice present.
• The Anglican–Roman Catholic International Commission's Eucharistic Doctrine (Windsor, 1971) reported "substantial agreement" on the Eucharist, explained in its 1979 Elucidation (Vatican text; USCCB).
• The World Council of Churches' Baptism, Eucharist and Ministry (Lima, 1982), with Catholic theologians taking part (WCC), affirmed the Eucharist as memorial, thanksgiving, and the real presence of Christ.
• Vatican II recognized that Protestant communities, when they commemorate the Lord's death at the Supper, "profess that it signifies life in communion with Christ and look forward to his coming in glory" (Unitatis Redintegratio 22; Catechism 1400).

Sources that speak to Protestant friends. These start from ground Protestants already trust: the Bible, the early Church, and their own tradition.

• The Bible's Jewish roots. Brant Pitre's Jesus and the Jewish Roots of the Eucharist (2011) reads the Last Supper through the Passover lamb, the manna, and the Bread of the Presence. It is written for Bible readers and is popular with evangelicals who are exploring the faith.
• St. Paul. Paul warns that whoever eats "without discerning the body" eats judgment on himself (1 Corinthians 11:27–29), and calls the cup "a participation in the blood of Christ" (1 Corinthians 10:16). Those words are hard to read as a mere symbol.
• The early Church, our shared heritage. St. Ignatius of Antioch, a disciple of the apostle John's generation, wrote around AD 110 that the Eucharist "is the flesh of our Savior Jesus Christ" (Letter to the Smyrnaeans 7). St. Justin Martyr, around AD 150, wrote that "not as common bread and common drink do we receive these" (First Apology 66). The Protestant historian J. N. D. Kelly concluded that early Eucharistic teaching was "in general unquestioningly realist" (Early Christian Doctrines, p. 440). See Catholic Answers: The Real Presence and ChurchFathers.org for the texts.
• Martin Luther himself. At the Marburg Colloquy (1529), Luther chalked "This is my body" on the table and refused to treat Christ's words as a symbol. Lutheran friends share this belief in Christ's true presence.

Videos for OCIA sessions.

• Bishop Barron on the Real Presence of Christ in the Eucharist (YouTube). A short commentary that works well as a discussion starter.
• Bishop Barron on the Sacrament of the Eucharist as Real Presence (YouTube). Another brief commentary from his classic series.
• The Real Presence of Jesus in the Eucharist (National Eucharistic Revival). Bishop Barron's full lecture at the 2020 Los Angeles Religious Education Congress; longer, best for catechists preparing to teach.
• What is the Eucharist? (Word on Fire). A hub of Bishop Barron's videos, homilies, and articles on the Eucharist, linked to the Catechism.

How to explain it with love. Start with John 6, where many disciples found this teaching hard and Jesus did not soften it (John 6:60–69). Explain that Catholics are not adding to Christ's sacrifice but receiving it. Be gentle about why non-Catholics are asked not to receive Communion: it is not a judgment on their faith but a sign that full unity is not yet here. The USCCB's Guidelines for the Reception of Communion (1996), printed in many missals, explain this and invite all to pray for that unity (Catechism 1398–1401).

What Catholics believe. Baptism is God's gift before it is our response. Catholics baptize infants because grace comes first, and no one, at any age, earns it.

• New birth in Christ. Baptism frees us from sin, makes us children of God, and joins us to Christ and his Church (Catechism 1213, 1262–1270; John 3:5).
• Why infants. Children are born into a fallen world and need the grace of new birth too. The Church baptizes them so they are not kept from that free gift (Catechism 1250–1252). Jesus said, "Let the children come to me; do not prevent them" (Mark 10:14).
• The faith of the family and the Church. An infant is baptized in the faith of the parents, godparents, and the whole Church, who promise to raise the child in that faith. Personal faith must then grow and be lived (Catechism 1253–1255).
• Once for all. Baptism leaves a permanent mark and is never repeated (Catechism 1272). That is why the Catholic Church recognizes valid Protestant baptisms and does not rebaptize (Catechism 1256, 1271).
• What the U.S. bishops teach. The USCCB's United States Catholic Catechism for Adults devotes a chapter to Baptism. The U.S. Catholic–Reformed Dialogue (2003–2007) produced These Living Waters: Common Agreement on Mutual Recognition of Baptism, in which Catholics and Reformed Christians recognize one another's validly administered baptisms. The Presbyterian Church (U.S.A.) joined the agreement in 2010 (USCCB, 2022).

What Protestants usually believe. Protestants are divided here. Lutherans, Presbyterians, Methodists, and Episcopalians baptize infants, so they already share this practice with Catholics. Baptists, Churches of Christ, Pentecostals, Mennonites, and most nondenominational churches practice believer's baptism: they baptize only those old enough to profess faith personally, usually by immersion. For many, baptism is an act of obedience that follows salvation rather than a means of grace.

Common ground from the dialogues.

• The World Council of Churches' Baptism, Eucharist and Ministry (Lima, 1982) asked both sides to see their practices as complementary: both stress God's grace and the need for a lifelong response of faith.
• The trilateral Lutheran–Mennonite–Catholic dialogue, Baptism and Incorporation into the Body of Christ, the Church (2012–2017; Mennonite World Conference), worked through this question with mutual respect and repentance for past persecution.
• These Living Waters shows how far agreement on baptism has come with churches that baptize infants.

Sources that speak to Protestant friends.

• Whole households in Scripture. The New Testament describes the baptism of entire households: Lydia's (Acts 16:15), the jailer's (Acts 16:33), and Stephanas' (1 Corinthians 1:16). Peter preached that "the promise is made to you and to your children" (Acts 2:38–39).
• The new circumcision. Paul links baptism to circumcision, the covenant sign given to Jewish boys at eight days old (Colossians 2:11–12).
• The early Church. The Apostolic Tradition, attributed to St. Hippolytus of Rome (around AD 215), instructs: "Baptize first the children," with parents answering for those who cannot speak for themselves. Origen (3rd century) wrote that "the Church received from the apostles the tradition of giving baptism even to infants" (Commentary on Romans 5.9).

How to explain it with love. Honor what believer's-baptism Christians rightly treasure: a personal, wholehearted commitment to Christ. Catholics treasure it too, which is why baptized children are confirmed, receive First Communion, and renew their baptismal promises every Easter. Adults who come through OCIA are also baptized on their own profession of faith. Above all, reassure Baptist and evangelical candidates that if their baptism was done with water in the name of the Trinity, the Church receives it as a true baptism, and they will not be baptized again.

What Catholics believe. Catholics love the Bible as the inspired Word of God. They believe God hands on his revelation through Scripture and Tradition together, faithfully guarded by the Church's teaching office. This is the root of the other four differences.

• One source, two streams. Vatican II teaches that Scripture and Tradition "flow from the same divine wellspring" and form "one sacred deposit of the Word of God" (Dei Verbum 9–10; Catechism 80–84). Tradition is not a second set of ideas added to the Bible; it is the living faith of the apostles, handed on in the Church's worship, life, and teaching.
• The Magisterium serves the Word. The Church's teaching office "is not superior to the Word of God, but is its servant" (Dei Verbum 10; Catechism 85–87). Its role is to guard and faithfully interpret what has been handed down, not to invent new revelation.
• Love for Scripture. The Church urges every Catholic to read the Bible, echoing St. Jerome: "Ignorance of the Scriptures is ignorance of Christ" (Catechism 131–133; Dei Verbum 25). The Mass is filled with Scripture, and its three-year cycle of readings covers much of the Bible.
• The canon. Catholics hold that the Church, guided by the Holy Spirit, discerned which books belong in the Bible (Catechism 120). The Catholic Old Testament includes seven books, such as Sirach and the Maccabees, that most Protestant Bibles leave out or place in an appendix.
• What the U.S. bishops teach. The USCCB publishes the New American Bible, Revised Edition and offers daily Mass readings online at bible.usccb.org. Its United States Catholic Catechism for Adults explains how revelation is handed on through Scripture and Tradition.

What Protestants usually believe. Most Protestants hold to sola scriptura: Scripture alone is the final authority for faith and life (often citing 2 Timothy 3:16–17). Church traditions are valued but can be corrected by Scripture. Even so, the major Reformers relied on the ancient Creeds and the Church Fathers, and Methodists speak of Scripture as primary, read alongside tradition, reason, and experience.

Common ground from the dialogues.

• The World Council of Churches' Faith and Order Conference at Montreal (1963), Scripture, Tradition and traditions, acknowledged that Scripture itself came to us through the living Tradition of the Church (full text).
• The U.S. Lutheran–Catholic Dialogue took up Scripture and Tradition in Round IX (published 1995; USCCB list of rounds).
• Evangelicals and Catholics Together issued Your Word Is Truth (2002; First Things), affirming together the Bible's authority and exploring how Tradition relates to it.

Sources that speak to Protestant friends.

• Scripture on tradition. Paul tells Christians to "hold fast to the traditions that you were taught, either by an oral statement or by a letter of ours" (2 Thessalonians 2:15), and calls the Church "the pillar and foundation of truth" (1 Timothy 3:15). John notes that not everything Jesus did was written down (John 21:25).
• Who gave us the Bible? The New Testament canon was recognized over the first centuries, confirmed by councils such as Hippo (393) and Carthage (397). Protestants and Catholics alike received the New Testament through that process.
• A convert's story. Scott Hahn, a former Presbyterian minister, describes in Rome Sweet Home (1993, with his wife Kimberly) how a student's question, "Where does the Bible teach sola scriptura?", began his journey (Coming Home Network: Rome Sweet Home).

How to explain it with love. Affirm first what we share: deep reverence for the Bible as God's Word. Show that Tradition is not a rival to Scripture but the living faith that carried it to us. Invite Protestant friends to see the Mass as Scripture prayed and to read the early Church Fathers alongside the Bible.

What Catholics believe. Those who die in God's grace and friendship, but are not yet fully purified, are assured of heaven. Before entering it, they are made perfectly holy through a final purification the Church calls purgatory (Catechism 1030–1031). It is not a second chance or a halfway hell; it is God's love finishing what it began. Because the Church is one family in Christ, the living can help the dead by prayer, the Mass, almsgiving, and works of penance (Catechism 1032).

• Rooted in Scripture. Judas Maccabeus made an offering for fallen soldiers so they might be freed from sin (2 Maccabees 12:42–46). Paul speaks of a person who is saved "but only as through fire" (1 Corinthians 3:13–15). Revelation says nothing unclean will enter the heavenly city (Revelation 21:27).
• The voice of the early Church. Christians prayed for the dead from the beginning, as catacomb inscriptions show. Tertullian (c. 200) mentions offerings for the dead on the anniversary of their death. St. Monica, dying, asked her son Augustine only to remember her at the altar of the Lord (Confessions 9.11).
• Christ is the fire. Pope Benedict XVI taught that the purifying fire may be Christ himself: meeting his gaze burns away what is false in us and frees us to be fully ourselves (Spe Salvi 47).
• Indulgences, rightly understood. An indulgence is the Church applying the merits of Christ and the saints to remove the temporal punishment due to sins already forgiven (Catechism 1471–1479). It is never for sale. The Council of Trent condemned the abuses Luther protested, Pope Pius V abolished indulgences tied to money in 1567, and Pope St. Paul VI reformed the practice in Indulgentiarum Doctrina (1967).
• Living it. November 2 is All Souls' Day, and the whole month of November is set aside to pray for the dead. Catholics have Masses offered for loved ones and pray, "Eternal rest grant unto them, O Lord."

What Protestants usually believe. Most Protestants reject purgatory. They hold that Christ's sacrifice fully covers the believer, who goes directly to be "with Christ" at death (Philippians 1:23; 2 Corinthians 5:8). The Reformation began in 1517 when Luther's 95 Theses protested the preaching of indulgences, and purgatory became a dividing line. Views vary across the traditions in this guide:

• Lutherans rejected purgatory, though Luther himself still accepted it in 1517.
• Presbyterians and Reformed Christians hold that the souls of the righteous are made perfect in holiness at death (Westminster Confession 32).
• Anglicans and Episcopalians officially rejected the "Romish" doctrine (Thirty-Nine Articles, Article 22), yet many pray for the dead, and the Book of Common Prayer includes such prayers.
• Methodists rejected purgatory in their Articles of Religion (Article 14), but John Wesley taught an intermediate state, "paradise," where souls await the resurrection and continue to grow in holiness.
• Baptists, Pentecostals, and most evangelicals see no basis for it, partly because they do not accept 2 Maccabees as Scripture.

Other Christian traditions. The Orthodox pray constantly for the dead in memorial services and believe in an intermediate state, but they reject the Western language of purifying punishment, a dispute at the Council of Florence (1439). Latter-day Saints teach a "spirit world" where the dead may still accept the gospel, and Jehovah's Witnesses hold that the dead are unconscious until the resurrection.

Common ground from the dialogues.

• The U.S. Lutheran–Catholic Dialogue devoted its eleventh round, The Hope of Eternal Life (completed 2010), to death, the intermediate state, purgatory, prayer for the dead, and indulgences. It found real convergence: both affirm that the dead remain in Christ's care and that the communion of saints is not broken by death (USCCB).
• Nearly all Christians agree that we must be made fully holy before we see God (Hebrews 12:14; Matthew 5:8). The difference is whether that happens instantly at death or as a process after it.

Sources that speak to Protestant friends.

• C.S. Lewis. The beloved Anglican writer said plainly, "I believe in Purgatory" (Letters to Malcolm, 1964, chapter 20). He argued that a person saved by grace would want to be cleansed before entering God's presence.
• Jerry L. Walls. A Protestant philosopher in the Wesleyan tradition, Walls makes the case for purgatory as sanctification completed in Purgatory: The Logic of Total Transformation (Oxford University Press, 2012).
• The early Church. Prayers for the dead in the catacombs and the Church Fathers show this was the faith of Christians long before the medieval period.

How to explain it with love. Begin with what we share: the hope of heaven and trust in Christ's saving work. Purgatory does not add to the Cross; it is the Cross completing its work in us. Present it as good news: no one has to be perfect at death, because God finishes what he starts (Philippians 1:6). Admit honestly that indulgences were abused in Luther's day and that the Church has corrected those abuses. And when a friend grieves, simply offer to pray for the one they lost; most people, of any tradition, are grateful.

• One God. Jews and Christians worship the God of Abraham, Isaac, and Jacob, and both pray the Shema: "Hear, O Israel: the Lord our God, the Lord is one" (Deuteronomy 6:4; Mark 12:29).
• The Hebrew Scriptures. The Law, the Prophets, and the Psalms belong to both. The Church teaches that the Old Testament is an indispensable part of Sacred Scripture whose books "retain a permanent value" (Catechism 121–123).
• A covenant that God keeps. St. Paul writes that "the gifts and the call of God are irrevocable" (Romans 11:29). The Church teaches that the Jewish people remain beloved by God (Nostra Aetate 4; Catechism 839).
• Jesus, Mary, and the apostles were Jews. Jesus prayed in the synagogue, kept the feasts, and went up to the Temple.
• Roots of Catholic worship. The Mass grows from Jewish worship: readings from Scripture, the Psalms, blessings over bread and wine, and the Passover meal behind the Last Supper.
• Shared moral vision. The Ten Commandments, the dignity of every person made in God's image (Genesis 1:27), care for the poor, the widow, and the stranger, and hope for God's kingdom of justice and peace.

• Jesus as Messiah and Son of God. This is the central difference. Christians confess Jesus as the promised Messiah and the eternal Son of God; Judaism does not, and continues to await the messianic age.
• The Trinity and the Incarnation. Judaism understands God's oneness in a way that does not include the Trinity or God becoming man.
• Reading Scripture. Jews read the Hebrew Bible through the Talmud and rabbinic tradition; Christians read it in light of Christ and the New Testament.
• Practice. Jewish life centers on the Torah: Shabbat from Friday evening to Saturday evening, kosher laws, and the cycle of feasts. Christians gather on Sunday, the day of the Resurrection.
• Evangelization. In 2015 the Vatican's Commission for Religious Relations with the Jews wrote that the Church "neither conducts nor supports any specific institutional mission work directed towards Jews" (The Gifts and the Calling of God Are Irrevocable, 40). Catholics still witness to Christ with humility and respect.
• Judaism is not one thing. Orthodox, Conservative, Reform, and Reconstructionist Jews differ widely, and many Jews are secular yet deeply Jewish by identity and culture.

Catholics must face this history honestly. For centuries Jews suffered in Christian lands: the charge of "deicide" (killing God), forced sermons and conversions, expulsions, ghettos, and violence. This "teaching of contempt" helped prepare the ground for the Shoah (Holocaust), in which six million Jews were murdered.

• Vatican II rejected the deicide charge. What happened in Christ's Passion "cannot be charged against all the Jews, without distinction, then alive, nor against the Jews of today." The Church "decries hatred, persecutions, displays of anti-Semitism, directed against Jews at any time and by anyone" (Nostra Aetate 4).
• We Remember: A Reflection on the Shoah (1998). The Holy See expressed sorrow for the failures of Christians during the Holocaust and called for repentance (teshuva).
• The Western Wall (March 26, 2000). On pilgrimage to Jerusalem, John Paul II placed a prayer in the Wall asking God's forgiveness for those who caused Jews to suffer, committing the Church to "genuine brotherhood with the people of the Covenant" (Vatican).
• Popes in synagogues. John Paul II in Rome (1986); Benedict XVI in Cologne (2005), New York (2008), and Rome (2010); Francis in Rome (2016). John Paul II was the first Bishop of Rome to enter a synagogue.

• Learn before you speak. Visit a synagogue service if invited, learn the major holy days (Rosh Hashanah, Yom Kippur, Passover, Hanukkah), and send greetings at those times.
• Watch our language. Never blame "the Jews" for Jesus' death, and explain Gospel phrases like John's "the Jews" carefully in teaching and preaching.
• Never make the friendship a project. Love Jewish neighbors for who they are, not as targets for conversion.
• Stand against antisemitism. Speak up when Jews are mocked, threatened, or attacked.
• Remember together. Join local Holocaust remembrance (Yom HaShoah) and interfaith services.
• Share your faith when asked. Speak about Jesus gently and honestly, with gratitude for the faith of Israel that first gave us the Scriptures and the Savior.

St. John Paul II called ecumenism an "exchange of gifts," and the same spirit applies here. These Jewish practices can deepen Catholic life without borrowing anything that belongs only to Judaism.

• Keeping the Sabbath. Jews welcome Shabbat with candles, a family meal, and real rest from work. Catholics can make Sunday just as set apart: a festive family meal, rest, and time for God, beginning Saturday evening as the Church's liturgical day does (Catechism 2184–2188; St. John Paul II, Dies Domini, 1998).
• Blessings through the day. Observant Jews say short blessings (berakhot) over food, on waking, at good news, even at the sight of a rainbow. Catholics can grow this habit alongside grace before and after meals, the Morning Offering, and the Church's Book of Blessings.
• A holy home. The mezuzah on the doorpost and prayer at the family table remind Jews that the home is sacred (Deuteronomy 6:4–9). Catholics can revive holy water fonts at the door, a home altar or prayer corner, house blessings at Epiphany, and the family as the "domestic church" (Catechism 1655–1658).
• Praying the Psalms. The Psalms were Jesus' own prayer book, prayed by Jews for three thousand years. Catholics can join this through the Liturgy of the Hours, even just Morning and Evening Prayer.
• Remembering the dead. Mourners recite the Kaddish for eleven months and mark each anniversary of a death (yahrzeit) with a candle. Catholics can keep a similar rhythm: Masses offered for the dead, a candle on the anniversary, and prayer for the souls in purgatory (Catechism 1032; 2 Maccabees 12:46).
• Teaching the faith at the table. The Passover seder is built around children's questions, and Jewish faith is passed on at home. Catholic parents can make the family table a place to tell the stories of the faith, especially on feast days.

Sources: Nostra Aetate (Vatican); Catechism 839–840; John Paul II, Address at the Rome Synagogue (1986); We Remember (1998); The Gifts and the Calling of God Are Irrevocable (2015); USCCB Catholic–Jewish dialogues.

• Compassion. Buddhist compassion (karuna) and loving-kindness (metta) echo Christ's call to love our neighbor and show mercy.
• Seeing through the world's false promises. Both traditions teach that wealth, pleasure, and status cannot satisfy the heart, and that selfish craving leads to suffering.
• Moral discipline. The Buddhist precepts (not to kill, steal, lie, commit sexual misconduct, or abuse intoxicants) closely parallel the Ten Commandments.
• Contemplation and silence. Buddhist meditation and Catholic contemplative prayer both value stillness, attention, and inner peace.
• Monastic life. Both have monks and nuns living in poverty, chastity, and community, and monastic exchanges have long been a bridge between them.
• Peace and nonviolence, and care for all living things.

• God. Christians believe in a personal God who creates the world out of love. Buddhism generally does not teach a creator God, and many Buddhists are agnostic on the question.
• Salvation. Christians are saved by grace through Jesus Christ. Buddhists seek liberation (nirvana) from the cycle of suffering, mainly through their own practice, though some schools, like Pure Land, rely on the help of a Buddha.
• The self. Christians believe each person has an immortal soul, loved by God forever. Buddhism teaches "no-self" (anatta), that there is no permanent self.
• Life after death. Christians hope for resurrection and eternal life with God; Buddhists speak of rebirth driven by karma, until liberation.
• Jesus. Buddhists may honor Jesus as a wise and compassionate teacher, but not as the Son of God and Savior.

Catholic–Buddhist relations have no history of persecution like that with Judaism, but much of their story is recent.

• Thomas Merton. The Trappist monk had three long meetings with the Dalai Lama at Dharamsala, India, in November 1968, about a month before his death. Merton wrote afterward, "I felt we had become very good friends" (Thomas Merton Center).
• Assisi, 1986. The Dalai Lama attended at John Paul II's invitation and sat at the head of the leaders of non-Christian religions (JP2online; Office of the Dalai Lama). See Popes Leading the Way.
• Monastic Interreligious Dialogue. Catholic Benedictine and Trappist monasteries have hosted Buddhist monks, and Catholic monks have lived in Buddhist monasteries, for decades.
• U.S. dialogue. In March 2003 the USCCB began an annual Catholic–Buddhist dialogue with the Dharma Realm Buddhist Association and the San Francisco Zen Center, covering grace, transformation, monastic vows, and Christ and the Buddha (USCCB; USCCB Buddhism). In 2015 USCCB staff joined Buddhist and Catholic leaders at Castel Gandolfo for a "dialogue of fraternity" that ended with an audience with Pope Francis (Committee History).

• Learn the basics. Know the Four Noble Truths and the Eightfold Path, and that Buddhism takes many forms.
• Respect sacred spaces. Remove shoes in a temple if asked, and treat images of the Buddha with respect.
• Share the contemplative tradition. Many Buddhists are surprised that Catholics have a rich history of silent prayer, from the Desert Fathers to St. John of the Cross.
• Work together. Join in service, care for creation, and peacemaking.
• Be honest about Christ. Share your faith gently, without watering it down or treating Buddhism as simply "the same thing."

As with Judaism, these practices can remind Catholics of treasures already in our own tradition, always centered on Christ.

• Daily silence and stillness. Buddhists set aside regular time to sit in silence. Catholics can do the same with quiet prayer before the Blessed Sacrament, Lectio Divina, or simply ten minutes of silence with God each morning.
• Attention to the present moment. Buddhist mindfulness trains attention on what is happening now. Catholics have Brother Lawrence's The Practice of the Presence of God and Jean-Pierre de Caussade's "sacrament of the present moment": finding God in each ordinary task.
• Prayer with beads. Buddhists use a mala to count repeated prayers. Catholics have the Rosary and, from the Eastern Churches, the Jesus Prayer on a prayer rope; both can be prayed slowly and attentively rather than rushed.
• Simplicity and detachment. Buddhist teaching on letting go of craving echoes Jesus' call to poverty of spirit (Matthew 5:3) and St. Ignatius' "holy indifference." Catholics can practice it by owning less and giving more.
• Mindful eating. Some Buddhists eat slowly and in silence, grateful for every part of the meal. Catholics can slow down grace, eat with gratitude, and recover Friday abstinence and fasting.
• Compassion for all creatures. Buddhist care for every living being echoes St. Francis and Pope Francis' Laudato Si' (2015) on care for our common home.
• Retreats. Buddhist meditation retreats are common; Catholics can rediscover silent retreats, such as the Spiritual Exercises of St. Ignatius or a few days at a monastery.

A Catholic voice: Arthur C. Brooks. Brooks, a practicing Catholic and Harvard professor who teaches and writes on happiness, has become good friends with the Dalai Lama over the years. He writes: "It was with the Tibetan Buddhist Monks that I learned how to pray my rosary better as a Catholic" (LinkedIn). His lessons for Catholics:

• Learn from people who are different from you. Brooks treats friendship with Buddhists as a way to deepen, not dilute, his own faith.
• Pray the Rosary as meditation. Watching Buddhist monks pray with focus taught him to pray the Rosary slowly and attentively, not as a rushed recitation.
• Detachment from empty rewards. In From Strength to Strength (2022), whose title comes from Psalm 84, Brooks draws on Eastern wisdom alongside Christian theology. He argues that "the greater our achievements and our attachment to them," the more painful decline becomes, and urges detachment from worldly success, service to others, and spiritual progress, especially in the second half of life (Denison Forum review). This echoes Jesus' warning against storing up treasure on earth (Matthew 6:19–21).
• Being needed. In "Dalai Lama: Behind Our Anxiety, the Fear of Being Unneeded" (New York Times, November 2016), co-written with the Dalai Lama, Brooks argued that much modern discontent comes from feeling unneeded, and that the cure is "a natural human hunger to serve our fellow men and women." They quote a Buddhist saying: "If one lights a fire for others, it will also brighten one's own way" (AEI reprint). Catholics will hear Jesus: "whoever wishes to be great among you shall be your servant" (Matthew 20:26). The two also wrote "All of Us Can Break the Cycle of Hatred" (Washington Post, March 11, 2019).

Five teachings of the Dalai Lama. In "Five Teachings of the Dalai Lama I Try to Live By" (The Atlantic, March 7, 2024; AEI reprint), Brooks shares lessons he lives by. Among them: each of us can do good locally without waiting for a powerful savior; "think, don't just feel," since reason can calm worry ("If there is a remedy, then what is the use of frustration? If there is no remedy, then what is the use of frustration?"); and "let it go," refusing to react to others' bad behavior as an act of kindness to them and to yourself. For Catholics these echo the works of mercy, Jesus' "Do not worry about tomorrow" (Matthew 6:34), and turning the other cheek (Matthew 5:39).

Further: Brooks's podcasts How to Build a Happy Life (The Atlantic) and The Art of Happiness, his Atlantic column "How to Build a Life," and Build the Life You Want (2023, with Oprah Winfrey), which names faith as one of four pillars of happiness alongside family, friendship, and work.

A caution: the Church encourages Catholics to learn from Eastern methods of prayer while keeping Christian prayer centered on a personal encounter with God (Congregation for the Doctrine of the Faith, Letter on Some Aspects of Christian Meditation, 1989).

• One God. Muslims and Christians worship the one God, Creator of heaven and earth, merciful and just, who speaks to humanity.
• Abraham. Both look to Abraham as a model of faith and obedience to God.
• Jesus and Mary. Muslims honor Jesus (Isa) as a great prophet, born of the Virgin Mary, who worked miracles and will return at the end of time. Mary (Maryam) is the only woman named in the Quran, more often than in the New Testament, and a whole chapter (Surah 19) bears her name (Nostra Aetate 3).
• Prayer, fasting, and almsgiving. These pillars of Muslim life are the same three practices the Church asks of Catholics in Lent (Matthew 6:1–18).
• Judgment and resurrection. Both believe in the resurrection of the dead and God's final judgment.
• Moral life. Both value family, modesty, care for the poor, and the sacredness of life.

• The Trinity. This is the deepest difference. Islam holds a strict oneness of God (tawhid) and rejects the Trinity, often understood as belief in three gods, which Christians also reject.
• Jesus. Muslims revere Jesus as a prophet but not as the Son of God. Most Muslims believe he was not crucified, but taken up to God.
• Revelation. Muslims believe the Quran is God's final, perfect word and that Muhammad is the "seal of the prophets." Christians believe God's full revelation is Jesus Christ himself (Hebrews 1:1–2; Dei Verbum 4).
• Salvation. Christians are saved by grace through Christ's death and resurrection. In Islam, people are judged by God according to faith and deeds, trusting in his mercy.
• Law and community. Islamic life is shaped by sharia, God's law as interpreted by scholars, and there is no single central authority like the Pope.

The history between Christians and Muslims includes conquest, the Crusades, and wars on both sides, and Christians still face persecution in some Muslim-majority countries today. Vatican II asked both to move forward: "Since in the course of centuries not a few quarrels and hostilities have arisen between Christians and Moslems, this sacred synod urges all to forget the past and to work sincerely for mutual understanding" (Nostra Aetate 3).

• Casablanca, 1985. On August 19, 1985, at the invitation of King Hassan II, St. John Paul II, the first pope to visit Morocco, spoke to about 80,000 young Muslims in Casablanca's stadium. He told them: "For us, Abraham is a very model of faith in God, of submission to his will and of confidence in his goodness. We believe in the same God, the one God, the living God" (Vatican; AsiaNews).
• Damascus, 2001. John Paul II became the first pope to enter a mosque, the Umayyad Mosque, and called for Christian–Muslim dialogue (Religion News Service).
• Abu Dhabi, 2019. On February 4, 2019, Pope Francis and the Grand Imam of Al-Azhar, Ahmad al-Tayyeb, signed the Document on Human Fraternity for World Peace and Living Together, during the first papal visit to the Arabian Peninsula (Vatican; USCCB).

• Learn the basics. Know the Five Pillars: the profession of faith (shahada), prayer five times a day (salat), almsgiving (zakat), fasting during Ramadan (sawm), and pilgrimage to Mecca (hajj).
• Mark their holy days. Send greetings for Ramadan and for Eid al-Fitr and Eid al-Adha; the Vatican sends a message to Muslims every year for the end of Ramadan.
• Be a good host. Offer halal or vegetarian food without pork or alcohol, and give space and time for prayer.
• Start with Mary and Jesus. Muslims are often surprised and moved by how much Catholics love Mary.
• Stand against prejudice. Speak up when Muslims are stereotyped or blamed for the acts of extremists, as the bishops have urged.
• Be honest about Christ. Share your faith gently, including what we believe about Jesus as Son of God and Savior.

• Prayer through the day. Muslims stop to pray five times daily wherever they are. Catholics have the Angelus (morning, noon, and evening) and the Liturgy of the Hours to sanctify the day the same way.
• Prayer with the body. Muslims bow and prostrate themselves before God. Catholics can recover kneeling, bowing, genuflecting with care, and the prostration of Good Friday as prayer with the whole body.
• Fasting together. During Ramadan whole communities fast from dawn to sunset and break the fast together. Catholics can take Lent and Friday penance more seriously, and fast as families and parishes.
• Generous giving. Zakat is a set portion of one's wealth given to the poor every year. Catholics can practice proportionate giving and tithing as part of stewardship.
• Reverence for Scripture. Muslims treat the Quran with great care and often memorize large portions. Catholics can honor the Bible in the home, keep it in a place of honor, and memorize favorite passages.
• Remembering God's name. Muslims constantly say "God willing" (in sha' Allah) and "Praise be to God" (al-hamdu lillah). Catholics can recover "Thanks be to God," "God willing," and short prayers through the day.

• Longing for God. Hindu devotion (bhakti) to a loving God echoes the Christian call to love God with all one's heart.
• Prayer and contemplation. Both have deep traditions of meditation, chant, and silent prayer.
• Asceticism. Fasting, pilgrimage, and simplicity of life are honored in both, as are monks and holy men and women (sannyasis).
• Reverence for the sacred. Both use images, candles, incense, flowers, and holy water in worship, and both see the sacred in the material world.
• Nonviolence and respect for life. Mahatma Gandhi's witness to nonviolence was honored by St. John Paul II.
• Hospitality and family. Both treasure family bonds, care of the elderly, and welcoming the guest.

• God. Christians believe in one personal God in three Persons. Hindus understand the divine in many ways: as the one ultimate reality (Brahman), as a personal God, or through many gods seen as forms of the one.
• Jesus. Many Hindus honor Jesus as a holy teacher or one divine incarnation among many. Christians believe he is the unique Son of God and only Savior (John 14:6; Acts 4:12).
• Rebirth and salvation. Hindus believe in rebirth (samsara) shaped by karma, and seek liberation (moksha). Christians believe we live one life, followed by judgment and resurrection, and are saved by grace.
• Creation and the self. Some Hindu schools teach that the soul is ultimately one with the divine. Christians teach that the soul is created by God, distinct from him, and called to communion with him.

Christians and Hindus have lived side by side in India since ancient times; the St. Thomas Christians of Kerala trace their faith to the apostle Thomas. The colonial era left wounds, and today Christians in parts of India face hostility and violence. Still, there is a long story of friendship.

• St. Mother Teresa of Calcutta served the poor and dying of every faith, most of them Hindu, and was honored across India.
• Raj Ghat, 1986. Beginning his pilgrimage to India on February 1, 1986, St. John Paul II prayed at Gandhi's memorial and called him "an outstanding and courageous witness to truth, love and nonviolence" (Vatican).
• A Catholic voice: Fr. Bede Griffiths. Born Alan Richard Griffiths in England (1906–1993), he entered the Catholic Church in 1932, became a Benedictine monk at Prinknash Abbey, and went to India in 1955. For about 35 years he led Shantivanam, a Christian ashram in Tamil Nadu open to people of all faiths, praying in Indian dress as Swami Dayananda, "bliss of compassion." He died there on May 13, 1993. His books include The Marriage of East and West and Return to the Centre (Encyclopedia.com; Bede Griffiths Sangha). Some Catholic theologians have questioned parts of his later thought, so readers should take him as a pioneer of dialogue, read alongside Church teaching.

• Learn the basics. Know a few key ideas (dharma, karma, moksha) and major festivals like Diwali and Holi; send greetings at Diwali as the Vatican does.
• Visit with respect. Remove shoes at a temple, accept blessed food (prasad) graciously or decline gently, and ask before taking photos.
• Mind food customs. Many Hindus are vegetarian, and most avoid beef.
• Share our own contemplative tradition, which many Hindus admire.
• Be honest about Christ. Speak of Jesus not as one teacher among many but as the Son of God, gently and with respect.

• Prayer at home. Many Hindu homes have a shrine where the family prays each day with a lamp and flowers. Catholics can keep a home prayer corner with a crucifix, an image of Mary, and a candle.
• Repetitive prayer of the heart. Hindus repeat a sacred name or mantra with beads. Catholics have the Jesus Prayer and the Rosary, prayed slowly as prayer of the heart.
• Pilgrimage. Millions of Hindus make pilgrimages to holy rivers and temples. Catholics can rediscover pilgrimage: to shrines, cathedrals, Rome, the Holy Land, or a local Marian shrine.
• Hospitality. Hindu tradition says "the guest is God" (atithi devo bhava). This echoes Jesus: "I was a stranger and you welcomed me" (Matthew 25:35).
• Simplicity and the later years. Hindu tradition honors a stage of life given to spiritual seeking and letting go. Catholics can see the second half of life the same way (see Arthur Brooks above).
• Feasts that fill the home. Diwali fills homes with light and joy. Catholics can keep Advent, Christmas, and Easter as feasts in the home, not only at church.

Pope St. John Paul II opened his 1998 encyclical Fides et Ratio (Faith and Reason) with an image Catholics should know by heart: "Faith and reason are like two wings on which the human spirit rises to the contemplation of truth." The Catechism says the same: "Though faith is above reason, there can never be any real discrepancy between faith and reason" (Catechism 159), and it teaches that God "can be known with certainty from the created world by the natural light of human reason" (Catechism 36, drawing on the First Vatican Council).

This matters for friendship. A Catholic never has to fear an honest question. Anyone who reasons carefully and sincerely is already walking on ground the Church considers holy.

The Church has always "baptized" the best of human thought rather than throwing it away.

• St. Augustine (354–430) tells in his Confessions (Book 7) how reading the Platonists helped lead him toward Christ. They showed him a spiritual, unchanging truth; the Gospel showed him that this Truth became flesh.
• St. Anselm (1033–1109) described theology as "faith seeking understanding" (fides quaerens intellectum).
• St. Thomas Aquinas (1225–1274) brought Aristotle into Christian thought in the Summa Theologiae. His principle that "grace does not destroy nature but perfects it" (Summa I, q. 1, a. 8) is the key to how Catholics approach every philosophy: keep what is true, and let Christ complete it.
• St. Paul in Athens (Acts 17:16–34) set the pattern. He debated Epicurean and Stoic philosophers, quoted their own poets, and started from what they already honored: an "unknown god."

Secular humanists believe human beings can live ethical, meaningful lives through reason, science, and compassion, without belief in God.

What we share: Deep respect for human dignity, human rights, education, science, and care for the poor. The Church has her own long tradition of Christian humanism, and Vatican II teaches that Christ "fully reveals man to man himself" (Gaudium et Spes 22).

How we differ: Catholics believe human dignity is rooted in being made in God's image (Genesis 1:27; Catechism 357), so it can't be voted away or earned. We also believe human beings are made for more than this world: for eternal communion with God.

Being good friends: Work side by side. Vatican II says that "while rejecting atheism, root and branch, the Church sincerely professes that all men, believers and unbelievers alike, ought to work for the rightful betterment of this world in which all alike live" (Gaudium et Spes 21). Food banks, literacy programs, and disaster relief are natural common ground.

Stoicism, the ancient philosophy of Zeno, Seneca, Epictetus, and the emperor Marcus Aurelius, has had a big modern revival, especially among young men looking for discipline and calm.

What we share: The Stoic virtues of wisdom, courage, justice, and temperance are the same four cardinal virtues the Church teaches (Catechism 1805–1809). Stoics value self-control, accepting what we cannot change, remembering death (memento mori), and living according to reason. Early Christian writers admired much of this.

How we differ: The Stoic "logos" is an impersonal reason running through the universe; for Christians, the Logos is a Person, Jesus Christ (John 1:1–14), who loves us. Stoics aim for freedom from troubling passions; Christians are called to love even when it hurts, as Christ wept at Lazarus's tomb (John 11:35). And Christian hope looks past death to resurrection.

Being good friends: Stoics often already practice a daily examination of conscience and journaling. Invite them to see how the Church's saints took these same practices and filled them with prayer.

Atheists don't believe God exists; agnostics believe we can't know. Many are sincere, thoughtful people, and some have been hurt by religious people along the way.

What we share: A love of truth, honest questioning, and often a strong moral sense. The Church teaches that those who, through no fault of their own, do not know God but sincerely seek the good can be open to salvation (Lumen Gentium 16; Catechism 847).

How we differ: Catholics hold that God's existence can be known by reason (Catechism 36) and that turning away from God is ultimately a loss for the human person. Vatican II also admits, humbly, that believers can share responsibility for atheism when they "conceal rather than reveal the authentic face of God" by poor teaching or poor example (Gaudium et Spes 19).

The Church reaching out: Pope Benedict XVI proposed a "Courtyard of the Gentiles," a place of dialogue between believers and nonbelievers, named for the court of the Jerusalem Temple open to everyone. He proposed it in December 2009, and the Pontifical Council for Culture launched it in Paris on March 24–25, 2011, with lectures at UNESCO and the Sorbonne and an evening gathering in front of Notre Dame (National Catholic Reporter).

Being good friends: Listen first. Don't argue to win; answer honestly, admit what you don't know, and let your life be the strongest argument.

• From humanists: a reminder that serving people in need is a work everyone can share, and that Catholics shouldn't leave the work of justice to others.
• From Stoics: the daily discipline of reflection, self-control, and remembering death, which the Church already treasures in the Examen and in Ash Wednesday's "Remember that you are dust."
• From atheists and agnostics: intellectual honesty. Their hard questions push Catholics to know their faith more deeply, as St. Peter urges: "Always be ready to give an explanation to anyone who asks you for a reason for your hope, but do it with gentleness and reverence" (1 Peter 3:15–16).

• Ask before you tell. Let your friend describe their own faith in their own words before you explain yours.
• Use their names for things. Say "Latter-day Saints," "the Lord's Supper," or "the Divine Liturgy" when that is what they say.
• Compare your best with their best. Never compare the ideals of Catholicism with the failures of someone else's tradition.
• Admit what you don't know. "I'm not sure, let me find out" builds trust.
• Share your own story. What your faith means to you is more persuasive than any argument.
• Leave the door open. The goal of a first conversation is a second one.

• Begin with: what we share, which is faith in Jesus Christ as Lord and Savior, love of Scripture, and baptism into Christ. Catholics see baptized Protestants as brothers and sisters in Christ.
• Avoid: suggesting they aren't "real" Christians, or opening with Mary, the Pope, or purgatory.
• Opening question: "How did you come to know Jesus?" or "What Bible passage means the most to you?"

• Begin with: honor for their ancient faith, their liturgy, their icons, and the sacraments we share.
• Avoid: calling them Protestants, or assuming they'll be glad to receive Communion at Mass; most Orthodox churches don't permit it.
• Opening question: "What do you love most about the Divine Liturgy?"

• Begin with: appreciation for their strong families, service, and devotion to Jesus.
• Avoid: the word "Mormon" (they prefer "members of the Church of Jesus Christ of Latter-day Saints" or "Latter-day Saints"), and mocking their history or temple practices.
• Opening question: "What does your faith mean for your family life?"

• Begin with: thanks for their courage and sincerity, even when they come to your door.
• Avoid: slamming the door or arguing for an hour on the porch. Be kind and brief if you're busy.
• Opening question: "What first drew you to the Witnesses?" If you want to go deeper, read John 1:1 and John 20:28 together.

• Begin with: the spiritual bond the Church has recognized since Vatican II. Jews are, as Pope St. John Paul II said, our "elder brothers."
• Avoid: trying to convert them in a first conversation, blaming Jews for the death of Christ (the Church rejects this), and treating Judaism as merely the "Old Testament religion."
• Opening question: "What does Shabbat look like in your home?"

• Begin with: our shared belief in one God, our reverence for Abraham, and Mary, who is honored in the Quran.
• Avoid: linking Islam with terrorism, offering pork or alcohol when hosting, and expecting a handshake across genders.
• Opening question: "What does Ramadan mean to you?" or "Who is Mary in Islam?"

• Begin with: respect for their practices of meditation, compassion, and simplicity.
• Avoid: calling Buddhism "just a philosophy," or assuming all Buddhists believe the same things.
• Opening question: "How did you begin your practice?"

• Begin with: respect for their prayer, family devotion, and hospitality.
• Avoid: calling their devotion "idol worship," or treating Hinduism as one single set of beliefs.
• Opening question: "What festival means the most to your family?" Diwali greetings are always welcome.

• Begin with: shared values, such as honesty, kindness, and serving others.
• Avoid: implying they can't be good without religion, or treating them as a project.
• Opening question: "What gives your life meaning?" or "What do you think makes a person good?"

• Invite them to Mass with you, and sit with them.
• Introduce them to your parish's OCIA (Order of Christian Initiation of Adults) coordinator.
• Share a simple resource, such as Bishop Barron's Word on Fire videos or the United States Catholic Catechism for Adults.
• Keep praying for them, and keep being their friend whatever they decide.
