The Orthodox Church is a family of Local Churches, just like the Churches of the Galatians, the Ephesians, the Romans, the Thessalonians, the Colossians etc, as described in the letters written to them by the holy Apostle Paul. Each of the Local Orthodox Churches has a main administrative figure, a chief bishop known as a Patriarch, or in the case of smaller Churches, a Metropolitan or Archbishop. However, the Church as a whole has no earthly head, because the head of the Orthodox Church is our Lord Jesus Christ. His authority is expressed in the Orthodox Church through the Holy Spirit as revealed particularly through Church Councils and the saints.
