Organization of the Eastern Orthodox Church

The Eastern Orthodox Church, officially the Orthodox Catholic Church and commonly known simply as the Orthodox Church is a communion composed of up to seventeen separate autocephalous (self-governing) hierarchical churches that profess Eastern Orthodoxy and recognise each other as canonical (regular) Eastern Orthodox Christian churches.^[1]^[2]^[3]^[4]

Each constituent church is self-governing;^[2] its highest-ranking bishop called the primate (a patriarch, a metropolitan or an archbishop) reports to no higher authority. Each regional church is composed of constituent eparchies (or dioceses) ruled by bishops. Some autocephalous churches have given an eparchy or group of eparchies with varying degrees of autonomy (meaning they have limited self-government). Such autonomous churches maintain varying levels of dependence on their mother church, usually defined in a tomos or another document of autonomy. In many cases, autonomous churches are almost completely self-governing, with the mother church retaining only the right to appoint the highest-ranking bishop (often an archbishop or metropolitan) of the autonomous church.^[5]

Normal governance is enacted through a synod of bishops within each church.^[6]

It is -- or should be -- a synod of bishops of all the 14 recognized autocephalous churches of Eastern Orthodox Christianity. Unlike the Catholic Church, which has a single, undisputed leader in the pope, the Orthodox Christians are divided into self-governing provinces, each with its own leadership. The council was meant to be the first meeting of all Orthodox leaders since 787, when the last of the seven ecumenical councils recognized by the heads of both the Eastern and Western Christian Church was held in Nicaea (present-day Iznik in northwestern Turkey).

Unlike the Catholic Church, which has a single supreme spiritual leader in the pope, the worldwide Orthodox Church is divided into 14 universally recognized, independent, autocephalous or self-headed churches. Each autocephalous church has its own head, or kephale in Greek. Every autocephalous church holds to the same faith as its sister churches. Most autocephalies are national churches, such as the Russian, Romanian and Greek Orthodox churches. Now, the Orthodox Church of Ukraine is claiming its place among the other autocephalous churches.

It elects its own primate and has the right to consecrate its own Holy Chrism, among other prerogatives unique to autocephalous Churches. [The term "autocephalous" literally means "self-heading."] An "autonomous" Church is self-governing to a certain degree in its internal matters, but its head is appointed or confirmed by the autocephalous Church, which nurtures it. An autonomous Church also receives its Holy Chrism from its "Mother Church."
