This article covers the organization of the Eastern Orthodox Churches rather than the doctrines, traditions, practices, or other aspects of Eastern Orthodoxy. Like the Catholic Church, the Orthodox Church claims to be the One Holy, Catholic and Apostolic Church. The term Western Orthodoxy is sometimes used to denominate what is technically a Vicariate within the Antiochian Orthodox Church and thus a part of the Eastern Orthodox Church as that term is defined here. The term "Western Orthodox Church" is disfavored by members of that Vicariate.
