Understanding Denominations
Defining a Christian Denomination
A Christian denomination represents a distinct religious body within Christianity, characterized by its unique name, organizational structure, and doctrinal tenets. While individual groups may prefer terms like church, convention, communion, or fellowship, the core distinction lies in their specific authority and theological interpretations. These divisions often stem from differing views on fundamental aspects such as the nature of Jesus, Trinitarianism, salvation, apostolic succession, eschatology, conciliarity, and papal supremacy.
The Movement Towards Ecumenism
Since the 20th century, Christian denominations have increasingly engaged in ecumenism, a movement focused on fostering mutual understanding and closer relationships among various Christian bodies. This initiative also aims for visible unity within the broader Christian Church, though the precise terms of this unity are often debated, as some groups assert themselves as the "one true church" or divinely instituted for specific doctrinal propagation. The World Council of Churches stands as the largest ecumenical organization in Christianity.
Global Christian Landscape (2024)
The global Christian population, estimated at over 2.6 billion in 2024, is broadly distributed across several major traditions. This distribution highlights the vast diversity within Christianity:
- Catholic: Approximately 48.6% of Christians.
- Wider Protestant (including Independents): Around 39.8%.
- Orthodox (Eastern and Oriental): Constituting about 11.1%.
- Other: A smaller segment at 0.50%.
This overview, while not exhaustive, aims to illustrate the rich tapestry of Christian diversity, ranging from ancient traditions to contemporary movements.
Early Christian Traditions
Foundations of Early Christianity
Early Christianity, spanning from its inception in the 1st century CE until the First Council of Nicaea in 325 CE, is often categorized into three primary branches based on their distinct theological and traditional developments: Jewish Christianity, Pauline Christianity, and Gnostic Christianity. While modern Christian denominations are largely considered descendants of Jewish and Pauline Christianities, Gnostic Christianity largely faded after the early Christian era, only to be rediscovered through later archaeological findings.
Pre-Nicaean Groups
Numerous Christian groups emerged during this formative period, each with unique interpretations and practices. These groups, appearing before the First Council of Nicaea, reflect the dynamic and often contentious theological landscape of early Christianity. Their existence highlights the diverse understandings of Christ's teachings and the nascent organizational structures of the faith.
Gnostic Christianity
Gnosticism, a prominent early Christian branch, emphasized a dualistic worldview and the attainment of salvation through esoteric knowledge (gnosis). These sects often presented alternative narratives of creation, the nature of God, and the role of Jesus, diverging significantly from what would become mainstream Christian doctrine. Despite their eventual decline, Gnostic texts and ideas offer invaluable insights into the rich intellectual and spiritual ferment of early Christian thought.
Late Ancient & Medieval Christian Groups
Following the First Council of Nicaea, new Christian groups emerged, leading to significant schisms that shaped the ecclesiastical landscape. The most enduring of these include the Church of the East and the Oriental Orthodox Churches, which diverged from the Roman-recognized state church in the 5th century. These splits were often driven by profound theological disagreements, particularly concerning Christology, as well as political and generational factors.
Church of the East
Historical Context and Schism
Emerging during the Sasanian Period, the Church of the East, also known as the Nestorian Church or the Church of Persia, formally separated from the Roman-recognized state church of Rome between 424 and 427 CE. This schism was rooted in theological differences, particularly its adherence to Dyophysite Christology, which emphasizes the distinctness of Jesus' divine and human natures. The Church of the East also referred to Mary as Christotokos (Christ-bearer) rather than Theotokos (God-bearer) and largely practiced aniconism, especially after the Islamic conquests.
Geographical Reach and Decline
Between the 11th and 14th centuries, the Church of the East maintained a significant presence across Inner Asia, influencing groups like the Keraites and Naimans. However, by the 15th century, its influence had largely receded, confining its communities primarily to the Eastern Aramaic-speaking Assyrian populations of northern Mesopotamia, a region where the church had initially flourished between the 1st and 3rd centuries.
Modern Successors and Syriac Christianity
The tumultuous period from the 16th to the 19th century saw the patriarchal lines of the Church of the East divide and eventually consolidate. Today, its primary successors include the Chaldean Catholic Church, which is in full communion with the Pope of Rome, and the Assyrian Church of the East. Minor related splinter groups, such as the Ancient Church of the East and the Chaldean Syrian Church, also exist. Collectively, these churches, part of the broader Syriac Christianity, accounted for approximately 1.12 million members as of 2025.
Oriental Orthodox Churches
Miaphysite Christology and Chalcedon
The Oriental Orthodox Churches are a collection of Christian churches that adhere to Miaphysite Christology and theology. They notably rejected the Council of Chalcedon in 451 CE and subsequent Byzantine councils. Following Chalcedon, many Eastern regions of the Byzantine Empire, particularly Mesopotamia, the Levant, and Egypt, continued as Miaphysite patriarchates, with Armenia and Ethiopia formally joining them shortly thereafter. These churches collectively represent a global membership of approximately 62 million as of 2019.
Monophysite vs. Miaphysite
While other Orthodox denominations, such as the Eastern Orthodox Church, sometimes label Oriental Orthodox Churches as "Monophysite," the Oriental Orthodox themselves reject this term. They prefer "Miaphysite," a term rooted in Cyril of Alexandria's Christological formula, which emphasizes the single, united nature of Christ, without confusion, change, division, or separation, distinguishing it from the Eutychian Monophysitism that posits a single, undifferentiated nature.
Ecumenical Engagement and Recognition
Historically, Oriental Orthodox Churches considered themselves the one, holy, catholic, and apostolic Church founded by Jesus. In contemporary ecumenical dialogues, there is increasing acceptance of Oriental Orthodoxy as a legitimate part of the broader Christian Church. All canonical Oriental Orthodox Churches are members of the World Council of Churches, with five forming the Standing Conference of Oriental Orthodox Churches. Various independent churches also exist within this tradition, some of which have passed in and out of recognition with mainstream churches.
Canonical Oriental Orthodox Churches
These are the recognized, mainstream Oriental Orthodox bodies:
Independent Oriental Orthodox Churches
These churches operate outside the full communion of the canonical Oriental Orthodox bodies:
Eastern Orthodox Church
Chalcedonian Tradition and Self-Identity
The Eastern Orthodox Church, officially known as the Orthodox Catholic Church, stands as one of the principal Chalcedonian Christian branches, alongside Roman Catholicism and Protestantism. It asserts its continuous lineage, based on apostolic succession, from the early Church as part of the state church of Rome. Each Eastern Orthodox church considers itself a part of the one true church, predating denominational divisions, and views itself as the original Church of Christ before the Great Schism of 1054 CE.
Global Presence and Internal Dynamics
With approximately 230 million members as of 2019, the Eastern Orthodox Church is the second-largest single Christian denomination globally, after the Catholic Church. While generally maintaining communion, historical instances of impaired communion, such as the Moscow–Constantinople schisms of 1996 and 2018, highlight internal administrative complexities. The church comprises various autocephalous (self-governing) jurisdictions, some with disputed administrative statuses, and also includes independent churches adhering to Eastern Orthodox traditions.
Canonical Eastern Orthodox Churches
These are the officially recognized autocephalous and autonomous jurisdictions within the Eastern Orthodox communion:
Independent Eastern Orthodox Churches
These churches are not in communion with the mainstream Eastern Orthodox Church. Some of these denominations consider themselves as part of True Orthodoxy or the Old Believers. True Orthodoxy, or Genuine Orthodoxy, separated from the mainstream church over issues of ecumenism and calendar reform since the 1920s; and the Russian Old Believers refused to accept the liturgical and ritual changes made by Patriarch Nikon of Moscow between 1652 and 1666. Several Old Believer denominations have reunified with the Russian Orthodox Church and subsequent wider Eastern Orthodox communion.
Other Orthodox Movements
Beyond formal church structures, various theological and spiritual movements have shaped Eastern Orthodoxy, reflecting diverse interpretations and practices within the tradition.
Catholic Church
The Universal Church and Its Branches
The Catholic Church, often referred to as the Roman Catholic Church, comprises 24 autonomous sui iuris particular churches: the Latin Church and 23 Eastern Catholic Churches. It asserts itself as the one, holy, catholic, and apostolic Church founded by Christ, with its origins traced to Saint Peter and the missionary work of Saint Paul. As such, the Catholic Church does not consider itself a denomination but rather the original, pre-denominational Church of Christ, claiming continuity through apostolic succession. With over 1.4 billion members as of 2025, it constitutes the majority of Western Christianity.
Latin (Roman) Catholic Church
The Latin Church is the largest and most widely recognized of the sui iuris churches within the Catholic communion. Headed by the Bishop of Rome (the Pope) from Vatican City, it represents the dominant tradition in Western Christianity. As of 2015, the Latin Church alone accounted for 1.255 billion members, making it a colossal spiritual and organizational entity.
Eastern (Oriental) Catholic Churches
These 23 particular churches are in full communion with the Pope, acknowledging his universal jurisdiction and authority, while maintaining their distinct Eastern liturgical rites and some theological emphases. They share the same core doctrine and sacraments with the Latin Church. As of 2019, these churches collectively had approximately 18 million members.
Independent Catholic Churches
Independent Catholic churches represent denominations that, while embodying catholicity, have separated from the Latin Church, often rejecting papal infallibility and supremacy. Their sacraments are generally recognized as valid but illicit by the Vatican. This movement traces its origins to the consecrations of bishops for the Old Catholic Archdiocese of Utrecht in 1724 without papal approval.
Catholic Movements
Various theological and spiritual movements have emerged within Catholicism, influencing its thought, practice, and social engagement.
Protestantism
Origins and Core Principles
Protestantism, a major movement within Christianity, traces its name to the 1529 Protestation at Speyer, but its origins are rooted in Martin Luther's challenge to the Roman Catholic Church in 1517. This period, known as the Reformation, led to the formation of numerous new churches. While some denominations intentionally separated from Rome, others, like Luther's followers, were excommunicated after seeking reform. Protestantism generally adheres to fundamental principles such as sola scriptura (scripture alone), justification by faith alone, and the universal priesthood of believers.
Contemporary Landscape
Today, the majority of Protestants belong to traditions such as Adventism, Anglicanism, Baptist churches, Calvinism (Reformed Protestantism), Lutheranism, Methodism, and Pentecostalism. Additionally, non-denominational, Evangelical, charismatic, neo-charismatic, and independent churches are experiencing significant growth, forming a substantial part of contemporary Protestant Christianity. The global Protestant population is estimated to range from 900 million to over 1 billion Christians.
Proto-Protestant Movements
Proto-Protestantism refers to movements that predated the formal Reformation (before 1517) but shared similar reformist impulses. Key figures included Peter Waldo, John Wycliffe, and Jan Hus. While not all these groups directly contributed to the later Protestant movement, some, like the Waldensians, eventually integrated into Reformed Protestantism. The Hussites are notably represented today by the Moravian Church and the Czechoslovak Hussite Church.
Lutheranism
Lutheranism, a foundational branch of Protestantism, identifies with the theology of Martin Luther. It originated from efforts to reform the Catholic Church, leading to excommunication. Lutherans are diverse, encompassing High Church, Confessional, Pietist, and Liberal traditions. Globally, Lutheranism had approximately 70-90 million members in 2018. The Lutheran World Federation, its largest communion, reported over 78 million members in 2023.
Radical Pietism
Radical Pietists are groups that separated from established Lutheran churches, emphasizing individual piety and a holy Christian life, distinct from Pietistic Lutherans who remained within the mainstream. This movement significantly influenced Anglicanism, particularly John Wesley, and contributed to the rise of Methodism.
Reformed Christianity (Calvinism)
Calvinism, or the Reformed tradition, emerged from the 16th-century Reformation, following the theological insights of John Calvin and John Knox. Reformed Christians differ from Lutherans on doctrines such as the real presence of Christ in the Eucharist, theories of worship, and the application of God's law. With 60 to 80 million adherents in 2018, and the World Communion of Reformed Churches boasting over 100 million members, it is one of the largest Protestant communities globally.
Anglicanism
Anglicanism, or Episcopalianism, often positions itself as a "via media" between Lutheranism and Reformed Christianity, and between Roman Catholicism and Protestantism. Anglicans self-identify as both Catholic and Reformed, though the "Protestant" label remains a point of discussion. The Anglican Communion, uniting most Anglicans, numbered over 89 million members as of 2025, making it the third-largest Christian communion.
Anabaptism
Anabaptists trace their origins to the Radical Reformation, distinguishing themselves from other early Protestants by their emphasis on "believer's baptism" (re-baptism). While some Anabaptists challenge their classification as an offshoot of Protestantism, they represent a significant tradition with approximately 2.1 million adherents as of 2015. Anabaptist groups are broadly categorized into Old Order, Conservative, and mainline/assimilated Anabaptism.
Baptists
Baptists emerged in 1609, influenced by figures like John Smyth, and experienced significant growth, particularly in the New World. While many Baptists align with Reformed theology, they often maintain distinct denominational structures. Some Baptist groups also adopt Presbyterian or Episcopal forms of governance. With 75 to 105 million adherents in 2018, and the Baptist World Alliance representing over 53 million members in 2023, the Baptist tradition is a significant global force.
Baptist Movements
Within the Baptist tradition, various movements have emerged, reflecting diverse theological emphases and practices.
Methodism
The Methodist movement emerged out of the work of Anglican priest John Wesley, who emphasized personal conversion (the New Birth) and holiness of heart. Wesley taught that the propagation of entire sanctification was the divine purpose for Methodists. While some Methodist denominations retain an episcopacy, others adopt a congregational polity. With 60-80 million adherents, and the World Methodist Council representing over 33 million members in 2024, Methodism is a significant global force. The holiness movement, which emerged within Methodism in the 19th century, further emphasizes these themes, with many holiness denominations being core members of the World Methodist Council.
Albright Brethren
The Albright Brethren were organized under the leadership of Jacob Albright, who converted to Methodism and preached to German-speaking people. Although the majority of the Albright Brethren merged with the United Brethren, two extant bodies continue today:
- Evangelical Church (ECNA)
- Evangelical Association
Evening Light Reformation
Churches of the Evening Light Reformation in 1880 emerged under the direction of Daniel Sidney Warner. While they emerged under the influence of the holiness movement, they adhere to a position of antidenominationalism. Classified as Holiness Restorationists, the Church of God (Anderson, Indiana) was the original work founded by Warner and its conservative holiness offshoot is the Church of God (Guthrie, Oklahoma). While the Church of God (Restoration) is listed here, it is distinguished from the two aforementioned bodies by unique doctrines that have taken it in a direction of its own.
- Church of God (Anderson, Indiana)
- Church of God (Guthrie, Oklahoma)
- Church of God (Restoration)
Keswickian Movement
The Higher Life movement emerged in the United Kingdom and emphasized the importance of sanctification, "the deeper and higher life." It became popularized through the Keswick Conventions; W.E. Boardman's Keswickian theology had an influence on A.B. Simpson, who established the Christian and Missionary Alliance.
- Alliance World Fellowship
- Borneo Evangelical Church (SIb Malaysia)
- Christian and Missionary Alliance
Quakers (Friends)
Quakers, or Friends, originated under the work of George Fox, who taught personal conversion to Christ, along with the doctrine of Christian perfection. The Friends have historically held that Christians are guided by the inward light to "make the witness of God" known to everyone.
Shakers
The United Society of Believers in Christ's Second Appearing was founded by Jane Wardley, Ann Lee, and Lucy Wright in 1747. At present, one active Shaker community remains, the Sabbathday Lake Shaker Village.
Plymouth Brethren
Plymouth Brethren is a conservative, low church, non-conformist, evangelical Christian movement whose history can be traced to Dublin, Ireland, in the late 1820s, originating from Anglicanism.
Irvingist Movement
The Catholic Apostolic churches were born out of the 1830s revival started in London by the teachings of Edward Irving, and out of the resultant Catholic Apostolic Church movement.
Pentecostal & Charismatic Christianity
Pentecostalism and Charismatic Christianity began in the 1900s. The two movements emphasize direct personal experience of God through baptism with the Holy Spirit. They represent some of the largest growing movements in Protestant Christianity. Pentecostalism is divided between its original branch, Holiness Pentecostalism (which teaches three works of grace) and Finished Work Pentecostalism (which views sanctification only in a progressive manner). Oneness Pentecostalism, which rejects the doctrine of the Holy Trinity, split from Finished Work Pentecostalism and is covered in its own section in this article. The charismatic movement was established within historic denominational traditions due to influence from Pentecostalism, e.g. the Catholic Charismatic Renewal in Roman Catholicism. According to the Pew Research Center, Pentecostals and Charismatics numbered some 280 million people in 2011.
Convergence Movement
The Convergence Movement originated from "The Chicago Call" in 1977, urging evangelical Protestants to reconnect with the liturgical historic roots of the Christian Church. It emphasizes the convergence of sacramental, evangelical, and charismatic streams; promoting biblical fidelity, creedal identity, and church unity.
Uniting & United Churches
These united or uniting churches are the result of a merger between distinct denominational churches (e.g., Lutherans, Anglicans, Presbyterians and the Continental Reformed churches). As ecumenism progresses, unions between various Protestants are becoming more and more common, resulting in a growing number of united and uniting churches. Major examples of uniting churches are the United Protestant Church of France (2013) and the Protestant Church in the Netherlands (2004). Churches are listed here when their disparate heritage marks them as inappropriately listed in the particular categories above.
Stone–Campbell Movement
Nondenominational Christianity arose in the 18th century through the Stone–Campbell Movement, with followers organizing themselves simply as "Christians" and "Disciples of Christ". The Stone–Campbell Movement was led by Barton Stone and Alexander Campbell.
Adventism
Adventism originated from the work of William Miller, who preached the end of the world and the second coming of Christ in 1843/44. After the Great Disappointment, this year was reinterpreted by Adventists as being the start of the investigative judgment.
Nondenominational & Evangelicals
The term Evangelical appears with the Reformation and reblossoms in the 18th and 19th centuries. Evangelical Protestantism modernly understood is an inter-denominational Protestant movement which maintains the belief that the essence of the Gospel consists of the doctrine of salvation by grace through faith in Jesus Christ's atonement.
Defunct Protestant Churches & Movements
These are protestant denominations, movements and organizations that existed historically, but no longer exist in modern times.
Other Protestant Churches & Movements
These are denominations, movements, and organizations deriving from mainstream Protestantism but are not classifiable under historic or current Protestant movements nor as parachurch organizations.
Miscellaneous Christian Groups
Diverse Independent Movements
This section encompasses independent and non-mainstream movements, denominations, and organizations formed during various times in the history of Christianity by splitting from mainline Catholicism, Eastern or Oriental Orthodoxy, or Protestantism not classified in the previous lists.
Christian Identitist
Christian Identity is a controversial interpretation of Christianity that posits people of European descent are the literal descendants of the ancient Israelites, and that Jews are not. This ideology is often associated with white supremacist and antisemitic views, and its adherents form distinct religious bodies.
Esoteric Christianity
Esoteric Christianity refers to Christian traditions that emphasize mystical knowledge, hidden meanings, and spiritual practices often kept secret from the general public. These groups often integrate elements of Western esotericism, seeking a deeper, more personal understanding of Christian truths.
Neo-Gnostic Movements
Neo-Gnosticism represents modern movements that draw inspiration from ancient Gnostic traditions, often reinterpreting Christian narratives through a lens of esoteric knowledge and spiritual awakening. These groups typically diverge from mainstream Christian doctrines on the nature of God, creation, and salvation.
Judeo-Christian Traditions
Judeo-Christian traditions encompass movements that emphasize the Jewish roots of Christianity, often integrating Jewish practices or interpretations. Messianic Judaism is a prominent example, where adherents believe in Jesus as the Messiah while maintaining Jewish identity and some Jewish customs.
Nontrinitarian Christianity
Nontrinitarian groups diverge from the historic Trinitarian theology, typically based on the Council of Nicaea, offering alternative interpretations of the divine nature. These groups present diverse understandings of God, Jesus, and the Holy Spirit.
Chinese Salvationist & East Asian Groups
These groups represent indigenous Christian or Christian-influenced movements primarily found in East Asia, often blending Christian beliefs with local cultural or religious elements.
Southcottist Movement
Southcottism refers to followers of Joanna Southcott, an English religious visionary who claimed to be a prophetess. Her followers anticipate the Second Coming of Christ and often hold unique eschatological beliefs.
Other Independent Groups
This category includes various other independent Christian groups and movements that do not fit into the more defined classifications, showcasing the vast and sometimes idiosyncratic diversity of Christian expression.
Parachurch Organizations
Beyond Denominational Boundaries
Parachurch organizations are Christian faith-based entities that operate outside and across traditional denominational lines. Their primary focus is often on social welfare, evangelism, and fostering inter-church cooperation. These organizations are not churches themselves but collaborate with or represent coalitions of churches, playing a crucial role in broader Christian outreach and service.
Christian Ideologies
Diverse Interpretations of Faith
A Christian movement is a theological, political, or philosophical interpretation of Christianity that is not necessarily represented by a specific church, sect, or denomination. These movements reflect the broad spectrum of thought and practice within the Christian faith, often influencing multiple denominations or existing as distinct intellectual currents.
British Israelism
British Israelism is an ideology asserting that people of British and related European descent are the literal descendants of the Ten Lost Tribes of ancient Israel. This belief forms the basis for several distinct religious organizations, often with unique interpretations of biblical prophecy and history.
Syncretic Traditions
Blending Christian Elements
Syncretic traditions are movements that incorporate elements of Christian practice or beliefs within broader religious contexts, which may only be loosely characterized as Christian. These traditions often arise from the blending of Christianity with indigenous religions, philosophical systems, or other spiritual practices, creating unique and diverse expressions of faith.
African Diaspora Religions
African diaspora religions are a number of related religions that developed in the Americas in various nations of the Caribbean, Latin America and the Southern United States. They derive from traditional African religions with some influence from other religious traditions, notably Christianity and Islam. Examples incorporating elements of Christianity include but are not limited to:
New Thought Movement
The relation of New Thought to Christianity is not defined as exclusive; some of its adherents see themselves as solely practicing Christianity, while adherents of Religious Science say "yes and no" to the question of whether they consider themselves to be Christian in belief and practice, leaving it up to the individual to define oneself spiritually.
Other Syncretists
Other Christian or Christian-influenced syncretic traditions and movements include:
