Christian denomination
A Christian denomination is a distinct religious body within Christianity that comprises all church congregations of the same kind, identifiable by traits such as a name, particular history, organization, leadership, theological doctrine, worship style and, sometimes, a founder. It is a secular and neutral term, generally used to denote any established Christian church. Unlike a cult or sect, a denomination is usually seen as part of the Christian religious mainstream. Most Christian denominations refer to themselves as churches, whereas some newer ones tend to interchangeably use the terms churches, assemblies, fellowships, etc. Divisions between one group and another are defined by authority and doctrine; issues such as the nature of Jesus, the authority of apostolic succession, biblical hermeneutics, theology, ecclesiology, eschatology, and papal primacy may separate one denomination from another. Groups of denominations—often sharing broadly similar beliefs, practices, and historical ties—are sometimes known as "branches of Christianity". These branches differ in many ways, especially through differences in practices and belief.
Individual denominations vary widely in the degree to which they recognize one another. Several groups say they are the direct and sole authentic successor of the church founded by Jesus Christ in the 1st century AD. Others, however, believe in denominationalism, where some or all Christian groups are legitimate churches of the same religion regardless of their distinguishing labels, beliefs, and practices. Because of this concept, some Christian bodies reject the term "denomination" to describe themselves, to avoid implying equivalence with other churches or denominations.
The Catholic Church, which has over 1.3 billion members or 50.1% of all Christians worldwide, does not view itself as a denomination, but as the original pre-denominational Church. The total Protestant population has reached around 1.047 billion in 2024, accounting for about 39.8% of all Christians. Sixteenth-century Protestants separated from the Catholic Church as a result of the Reformation, a movement against doctrines and practices which the Reformers perceived to be in violation of the Bible. Together, Catholicism and Protestantism compose Western Christianity. Western Christian denominations prevail in Sub-Saharan Africa, Europe, North America, Oceania and South America.
The Eastern Orthodox Church, with an estimated 230 million adherents, is the second-largest Christian body in the world and also considers itself the original pre-denominational Church. Orthodox Christians, 80% of whom are Eastern Orthodox and 20% Oriental Orthodox, make up about 11.9% of the global Christian population. The Eastern Orthodox Church is itself a communion of fully independent autocephalous churches that recognize each other, for the most part. Similarly, the Catholic Church is a communion of sui iuris churches, including 23 Eastern ones. The Eastern Orthodox Church, the 23 Eastern Catholic Churches, the Oriental Orthodox communion, the Assyrian Church of the East, the Ancient Church of the East, and the Eastern Lutheran Churches constitute Eastern Christianity. There are certain Eastern Protestant Christians that have adopted Protestant theology but have cultural and historical ties with other Eastern Christians. Eastern Christian denominations are represented mostly in Eastern Europe, North Asia, the Middle East, Northeast Africa, and India.
Christians have various doctrines about the Church and about how the divine church corresponds to Christian denominations. The Catholic, Eastern Orthodox, Oriental Orthodox, Church of the East and Lutheran denominations, each hold that only their own specific organization faithfully represents the one holy catholic and apostolic Church, to the exclusion of all others. Certain denominational traditions teach that they were divinely instituted to propagate a certain doctrine or spiritual experience, for example the raising up of Methodism by God to propagate entire sanctification, or the launch of Pentecostalism to bestow a supernatural empowerment evidenced by speaking in tongues on humanity.
Restorationism emerged after the Second Great Awakening and collectively affirms belief in a Great Apostasy, thus promoting a belief in restoring what they see as primitive Christianity. It includes Mormons, Irvingians, Christadelphians, Swedenborgians, Jehovah's Witnesses, among others, although beliefs between these religions differ greatly.
Generally, members of the various denominations acknowledge each other as Christians, at least to the extent that they have mutually recognized baptisms and acknowledge historically orthodox views including the divinity of Jesus and doctrines of sin and salvation, even though doctrinal and ecclesiological obstacles hinder full communion between churches. Since the reforms surrounding the Second Vatican Council of 1962–1965, the Catholic Church has referred to Protestant churches as ecclesial communities, while reserving the term "church" for apostolic churches, including the Eastern and Oriental Orthodox Churches, as well as the Ancient and Assyrian Churches of the East. But some non-denominational Christians do not follow any particular branch, though they sometimes are regarded as Protestants.
Terminology
Each group uses different terminology to discuss their beliefs. This section will discuss the definitions of several terms used throughout the article, before discussing the beliefs themselves in detail in following sections.A denomination within Christianity can be defined as a "recognized autonomous branch of the Christian Church"; major synonyms include "religious group, sect, Church," etc. "Church" as a synonym, refers to a "particular Christian organization with its own clergy, buildings, and distinctive doctrines"; "church" can also more broadly be defined as the entire body of Christians, the "Christian Church".
Some traditional and evangelical Protestants draw a distinction between membership in the universal church and fellowship within the local church. Becoming a believer in Christ makes one a member of the universal church; one then may join a fellowship of other local believers. Some evangelical groups describe themselves as interdenominational fellowships, partnering with local churches to strengthen evangelical efforts, usually targeting a particular group with specialized needs, such as students or ethnic groups. A related concept is denominationalism, the belief that some or all Christian groups are legitimate churches of the same religion regardless of their distinguishing labels, beliefs, and practices.
The views of Protestant leaders differ greatly from those of the leaders of the Catholic Church and the Eastern Orthodox Church, the two largest single Christian churches. Each church makes mutually exclusive statements for itself to be the direct continuation of the church founded by Jesus Christ, from whom other denominations later broke away. These churches, and a few others, reject denominationalism. For the purpose of academic study of religion, the main families of Christianity are categorized as a denomination, that is, "an organized body of Christians."
Historically, Catholics would label members of certain Christian churches by the names of their founders, either actual or purported. Such supposed founders were referred to as heresiarchs. This was done even when the party thus labeled viewed itself as belonging to the one true church. This allowed the Catholic party to say that the other church was founded by the founder, while the Catholic church was founded by Christ. This was done intentionally in order to "produce the appearance of the fragmentation within Christianity" – a problem which the Catholic side would then attempt to remedy on its own terms.
Although Catholics reject branch theory, Pope Benedict XVI and Pope John Paul II used the "two lungs" concept to relate Catholicism with Eastern Orthodoxy.
Major branches
Christianity can be taxonomically divided into six main groups: the Church of the East, Oriental Orthodoxy, Eastern Orthodoxy, Catholicism, Protestantism, and Restorationism. Protestantism includes many groups which do not share any ecclesiastical governance and have widely diverging beliefs and practices. Major Protestant branches include Adventism, Anabaptism, Anglicanism, Baptists, Lutheranism, Methodism, Moravianism, Quakerism, Pentecostalism, Plymouth Brethren, Reformed Christianity, and Waldensianism. Reformed Christianity itself includes the Continental Reformed, Presbyterian, Evangelical Anglican, Congregationalist, and Reformed Baptist traditions. Anabaptist Christianity itself includes the Amish, Apostolic, Bruderhof, Hutterite, Mennonite, River Brethren, and Schwarzenau Brethren traditions.Within the Restorationist branch of Christianity, denominations include the Irvingians, Swedenborgians, Christadelphians, Latter Day Saints, Jehovah's Witnesses, La Luz del Mundo, and Iglesia ni Cristo.
Christianity has denominational families and also has individual denominations. The difference between a denomination and a denominational family is sometimes unclear to outsiders. Some denominational families can be considered major branches. Groups that are members of a branch, while sharing historical ties and similar doctrines, are not necessarily in communion with one another.
There were some movements considered heresies by the early Church which do not exist today and are not generally referred to as denominations: examples include the Gnostics, the Ebionites, and the Arians, Bogomilism and the Bosnian Church. The greatest divisions in Christianity today, however, are between the Eastern and Oriental Orthodox, Catholics, and the various denominations formed during and after the Protestant Reformation. There also exists a number of non-Trinitarian groups.
