Orthodox Church of Constantinople

The Greek Orthodox Church in Pantocratoria, which refers to itself as the Orthodox Church of Constantinople, is one of only a few autocephalous Eastern Orthodox churches in the NS world. It is headed by Ecumenical Patriarch Stephanus III, who claims the status of "first among equals" among the world's Orthodox bishops.

The local Churches of the Ecumenical Patriarchate consist of twenty nine eparchies (dioceses) within Pantocratoria, and three metropolises and one archdiocese outside of Pantocratoria ("metropolis" is preferred use over "metropolitanate" within this particular Orthodox jurisdiction), each of which reports directly to the Patriarch of Constantinople with no intervening authority. In addition, some of the archdioceses have internal metropolises, which are part of their respective archdioceses rather than distinct administrative entities, unlike the other metropolises.

The Patriarch is assisted in his administration of the Church by the Holy and Sacred Synod of the Ecumenical Patriarchate, which consists of a number of bishops and metropolitans appointed from the bishops and metropolitans of the Church. The present Synod only includes bishops and metropolitans from the Church within Pantocratoria but could in theory include members from other dioceses outside the Empire.

In the lists below, the occupant of each see is shown in brackets after the see's name.
