REL 10043 Trends in World Christianity: Major Christian Traditions

A comprehensive vocabulary review set covering the major Christian traditions (Roman Catholicism, Eastern and Oriental Orthodoxy, Protestantism, and Pentecostalism), their historical splits, structural polities, liturgical practices, and global manifestations.

Christian Tradition

A major historical branch of Christianity that possesses its own theological beliefs, worship patterns, leadership structure, and institutional heritage, handed down and developed gradually across generations.

Denomination

Christian Movement

A shared spiritual identity, theological emphasis, or renewal current—such as Evangelicalism, the Charismatic movement, or the Ecumenical movement—that is not confined to one denomination and easily crosses traditional ecclesial boundaries.

Council of Chalcedon (AD 451)

A major ecumenical church council that defined Jesus Christ as one person existing in two natures (fully divine and fully human); churches accepting this became the Chalcedonian stream (Catholic, Eastern Orthodox, Protestant), while those rejecting it formed the Oriental Orthodox Churches.

Great Schism of 1054

The formal historical split between the Western church (centered in Rome as the Catholic Church) and the Eastern churches (centered in Constantinople as Eastern Orthodoxy).

Latin Church

Eastern Catholic Churches

A group of 23 distinct historical churches originating from Byzantine, Oriental, or other Eastern traditions that negotiated full communion with Rome, accepting papal authority and Catholic doctrine while retaining their distinctive Eastern liturgies, canon law, and languages.

Diocese

Oriental Orthodox Communion

A historical family of six churches (Ethiopian, Coptic, Eritrean, Armenian, Syriac, and Malankara) that rejected the Council of Chalcedon, recognize only the first three ecumenical councils, and employ historic tongues such as Ge'ez, Coptic, and Syriac.

Christ Pantokrator

A traditional Orthodox icon located prominently in the church dome or oculus depicting Christ as Ruler of All gazing over the congregation, expressing Christ's active divine presence with earthly worshipers.

Charismatic Movement

A cross-traditional renewal movement emphasizing the present power and gifts of the Holy Spirit whose participants remain within their historic Catholic, Anglican, or Protestant communions rather than joining Pentecostal denominations.

Orthopathy

Right spiritual feelings, affections, and lived experiential encounters with God, which receives prime emphasis in Pentecostal spirituality alongside orthodoxy (right belief) and orthopraxy (right action).

Spirit Baptism

In Pentecostal theology, a powerful spiritual experience distinct from and following conversion that equips the believer for ministry; classical Pentecostalism teaches speaking in tongues as its initial physical evidence.

Full Gospel

A theological framework popular in Pentecostal traditions presenting Jesus Christ under five primary roles: Savior, Sanctifier, Spirit-Baptizer, Healer, and Coming King.

Classical Pentecostals vs. Neo-Charismatics

Ecumenical Movement

A cooperative movement across divided Christian bodies seeking to foster Christian unity, mutual understanding, theological reconciliation, and joint engagement in social service and mission.

Believers' Baptism

The sacramental practice held by Baptist, Anabaptist, and most Pentecostal traditions that restricts baptism exclusively to individuals old enough to make a conscious personal profession of faith, rejecting infant baptism.

Fundamentalist–Modernist Controversy

A significant early 20th-century Protestant dispute between fundamentalists defending biblical inerrancy and traditional doctrines (virgin birth, miracles, bodily resurrection) and modernists seeking to reframe faith using historical-critical and modern scientific insights.

Conservative Resurgence

A sustained campaign beginning in 1979 within the Southern Baptist Convention in which theologically conservative leaders secured control of denominational offices, agency leadership, and seminaries to enforce biblical inerrancy.

Episcopal Governance

A hierarchical model of church polity where authority over clergy, ordination, and diocesan operations is vested in bishops, characteristic of Anglican and Methodist churches as well as Catholicism and Orthodoxy.
