To be “orthodox” means to have the right beliefs. Eastern (Greek) Orthodox Christians affirm the creeds of the first seven Ecumenical Church Councils, which established the doctrines of the Holy Trinity and the nature of Christ.  There is no singular “orthodox church;” instead, the Orthodox Communion is an association of national churches, each with its own leader or patriarch. All Eastern (Greek) Orthodox churches share the same theology and practices (which are both liturgical and sacramental). In the Middle East, these churches include the Patriarchate of Jerusalem, the Patriarchate of Antioch and All the East, and the Patriarchate of Alexandria and All Africa.
