Differences Between Christian Denominations

Christianity is one of the most diverse religious traditions in the world. While all Christians center their faith on the life, teachings, and resurrection of Jesus Christ, the ways they worship, interpret Scripture, and live out their beliefs can vary widely. Understanding the differences between Christian denominations can help you find a spiritual home that reflects your values, traditions, and convictions.

Below, we’ll explore five broad categories of Christianity—Catholic, Evangelical, Post-Evangelical, Mystic, and Other Traditions—and highlight how they differ from one another. We’ll also note which communities are open and affirming to LGBTQ+ people.

Catholic Christianity

Catholicism is the oldest and largest Christian tradition, tracing its history directly back to the early church and the apostles. Catholic worship emphasizes sacrament, liturgy, and continuity with tradition.

Main Tenets:

Authority of the Pope and church tradition alongside Scripture.
Sacraments (baptism, Eucharist, confirmation, confession, marriage, holy orders, anointing of the sick) as central means of grace.
Strong emphasis on the Virgin Mary and the communion of saints.

Examples of Catholic Denominations:

Roman Catholic Church (the largest body of Christians worldwide).
Eastern Catholic Churches (in communion with Rome but with their own liturgical traditions).

Queer Affirming? The Roman Catholic Church officially teaches traditional views on sexuality and marriage, though some local parishes and communities are LGBTQ+ affirming in practice.

When exploring the differences between Christian denominations, Catholicism often stands out for its hierarchical structure and sacramental theology.

Evangelical Christianity

Evangelicalism is a movement that spans across Protestant denominations, emphasizing personal faith, biblical authority, and evangelism.

Main Tenets:

Authority of the Bible as the ultimate guide for life and faith.
Necessity of personal conversion (“being born again”).
Missionary zeal and sharing the gospel with others.

Examples of Evangelical Denominations:

Southern Baptist Convention
Assemblies of God
Evangelical Free Church of America
Non-denominational Evangelical Churches

Queer Affirming? Most Evangelical denominations are not queer affirming, though small pockets of affirming congregations exist.

The differences between Christian denominations within Evangelicalism often come down to worship style (charismatic vs. traditional) and views on social issues.

Post-Evangelical Christianity

Post-Evangelicalism describes individuals and communities who have roots in Evangelical Christianity but who are rethinking, deconstructing, or reconstructing their faith in new ways. This is a growing movement, particularly in the U.S.

Main Tenets:

Openness to questioning inherited beliefs.
Emphasis on justice, inclusion, and community over dogma.
Flexible relationship with Scripture—valued, but interpreted through historical, cultural, and personal lenses.

Examples of Post-Evangelical Denominations or Communities:

United Church of Christ
Christian Church (Disciples of Christ)
Progressive Non-Denominational Communities
Expressions within the Methodist Church — typically the United Methodist Church (especially post-split congregations)

Queer Affirming? Most post-Evangelical communities are fully affirming of LGBTQ+ people, often leading the way in advocating for inclusion.

When asking about the differences between Christian denominations, post-Evangelical churches stand out for their emphasis on inclusion and their willingness to evolve beyond traditional boundaries.

Mystic Christianity

Mystic Christianity refers to streams of faith that emphasize spiritual experience, contemplation, and union with God over rigid doctrinal systems. Mysticism exists within Catholic, Orthodox, and Protestant traditions, but has a unique flavor of its own.

Main Tenets:

Emphasis on prayer, meditation, and contemplative practice.
A focus on the “inner life” and direct encounter with God.
Less concern with dogma, more with spiritual transformation.

Examples of Mystic-leaning Denominations or Movements:

Quakers (Religious Society of Friends)
Some expressions of Anglicanism and Episcopal traditions
Certain Catholic monastic orders (Benedictine, Franciscan, Carmelite)
New monastic and contemplative communities

Queer Affirming? Many mystic traditions, especially Quakers and the Episcopal Church, are queer affirming. Catholic monasticism is mixed, with official teaching being non-affirming but some communities welcoming LGBTQ+ members.

In terms of the differences between Christian denominations, mystic Christianity is distinct for its experiential, contemplative approach to faith.

Other General Christian Traditions

Beyond these categories, there are other major Christian traditions that are essential to understanding the full picture of faith diversity.

Eastern Orthodox Christianity

Strong focus on liturgy, icons, and ancient church traditions.
Independent national churches (Greek Orthodox, Russian Orthodox, etc.).
Generally non-affirming of LGBTQ+ identities.

Mainline Protestantism

Includes denominations such as the Presbyterian Church (USA), Evangelical Lutheran Church in America, United Methodist Church (post-split), and Episcopal Church.
More structured than Evangelicals, but less hierarchical than Catholics.
Many of these denominations are queer affirming or moving in that direction.

Pentecostalism

Strong emphasis on the Holy Spirit, spiritual gifts, and charismatic worship.
Includes Assemblies of God, Church of God in Christ, and other movements.
Most Pentecostal groups are non-affirming, though inclusive Pentecostal churches are emerging.

These streams highlight even more differences between Christian denominations, especially when it comes to worship style, leadership structures, and inclusion of LGBTQ+ people.

Why Understanding the Differences Matters

Learning the differences between Christian denominations is not just about history or theology—it’s about finding belonging. For some, Catholic liturgy feels like home; for others, the energy of Evangelical worship resonates. Post-Evangelicals and mystics may find their faith thriving in more inclusive or contemplative spaces.

The differences between Christian denominations also shape how churches respond to today’s pressing issues: LGBTQ+ affirmation, racial justice, women in leadership, and approaches to Scripture. Understanding these distinctions can guide you as you seek a community that nurtures both your faith and your identity.
