Synod of bishops (Orthodox)

In several of the Eastern Orthodox churches and Eastern Catholic Churches, the patriarch or head bishop is elected by a group of bishops called the Holy Synod. For instance, the Holy Synod is a ruling body of the Georgian Orthodox Church.

In Oriental Orthodoxy the Holy Synod is the highest authority in the church and it formulates the rules and regulations regarding matters of church organisation, faith, and order of service.

The principle of summoning a synod or council of ecclesiastical persons to discuss some grave question affecting the Church goes back, of course, to the very beginning of her history. Since the day when the Apostles met at Jerusalem to settle whether Gentile converts were to keep the Old Law (Acts 15:6–29), it had been the custom to call together such gatherings as occasion required. Bishops summoned synods of their clergy, metropolitans and patriarchs summoned their suffragans, and then since 325 there was a succession of those greatest synods, representing the whole Catholic world, that are known as general councils.

The Most Holy Synod or Most Holy Governing Synod (Святейший Правительствующий Синод) was a congregation of Orthodox church leaders in Russia. It was established by Peter the Great, Stefan Yavorsky and Feofan Prokopovich in January 1721 to replace the Patriarchate of Moscow. It was abolished following the February Revolution of 1917 and replaced with a restored patriarchate under Tikhon of Moscow. In modern Russia the Holy Synod of the Russian Orthodox Church is the highest governing body of the Russian Orthodox Church between Sobors. It is headed by the Patriarch of Moscow and all the Rus'.
