Denominations of Christianity - Major Branches

Major Branches

Christianity has denominational families (or movements) and also has individual denominations (or communions). Within these denominational families and movements are (often further denominational families and) various individual denominations or communions. The difference between a denomination and a denominational family is sometimes unclear to outsiders. Some denominational families can be considered major branches.

Christianity is composed of, but not limited to, five major branches of Churches: Catholic, Eastern Orthodox, Oriental Orthodox, Anglican, and Protestant (Some groupings include Anglicans amongst Protestants). The Assyrian Church of the East is also a distinct Christian body, but is much smaller in adherents and geographic scope. Each of these six branches has important subdivisions. Because the Protestant subdivisions do not maintain a common theology or earthly leadership, they are far more distinct than the subdivisions of the other five groupings. Denomination typically refers to one of the many Christian groupings including each of the multitude of Protestant subdivisions.

Denominationalism is an ideology which views some or all Christian groups as being, in some sense, versions of the same thing regardless of their distinguishing labels. Not all churches teach this. The Catholic and Orthodox Churches do not use this term as its implication of interchangeability does not agree with their theological teachings. There are some groups which practically all others would view as apostate or heretical, and not legitimate versions of Christianity.

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 (who had believed in an esoteric dualism called gnosis), the Ebionites (who denied the divinity of Jesus), and the Arians (who subordinated the Son to the Father by denying the pre-existence of Christ, thus placing Jesus as a created being), Bogumilism and Bosnian Church. The greatest divisions in Christianity today, however, are between Eastern Orthodoxy, Catholicism, and various denominations formed during and after the Protestant Reformation. There also exists in Protestantism and Orthodoxy various degrees of unity and division.

Comparisons between denominational churches must be approached with caution. For example, in some churches, congregations are part of a larger church organization, while in other groups, each congregation is an independent autonomous organization. This issue is further complicated by the existence of groups of congregations with a common heritage that are officially nondenominational and have no centralized authority or records, but which are identified as denominations by non-adherents. Study of such churches in denominational terms is therefore a more complex proposition.

Some groups count membership based on adult believers and baptized children of believers, while others only count adult baptized believers. Others may count membership based on those adult believers who have formally affiliated themselves with the congregation. In addition, there may be political motives of advocates or opponents of a particular group to inflate or deflate membership numbers through propaganda or outright deception.
