Holy Synod

The affairs of the patriarchate are conducted by the Holy Synod, presided over by the Ecumenical Patriarch. The synod has existed since some time prior to the fourth century and assists the patriarch in determining the affairs of the possessions under his jurisdiction. The synod first developed from what was referred to as the resident synod, composed of the patriarch, local bishops, and any Orthodox bishops who were visiting in the imperial capital of Constantinople. After the fall of Constantinople, the synod's membership became limited to bishops of the patriarchate.

The Holy and Sacred Synod, presided over by His All-Holiness Ecumenical Patriarch Bartholomew I, is composed of twelve hierarchs, each serving a year-long term, with half of the synod's members changing every six months in March and September.

The current members of the Holy and Sacred Synod serving from September 1, 2023 – February 29, 2024, are as follows:

Notable hierarchs of the Ecumenical Patriarchate are the popular writer Kallistos (Timothy) Ware, an assistant-bishop in the Archdiocese of Thyateira and author of The Orthodox Church, the best-known introduction to the Orthodox Church in English, and John Zizioulas, Metropolitan of Pergamon, a well-known professor of systematic theology.

The right of non-Turkish members of the synod (from Northern Greece, the Dodecanese, America and Western Europe) to convene appears to be threatened by a recent declaration from the Istanbul Governor reported in the Freiburg archdiocesan magazine.
