What is the Headquarters of Eastern Orthodox Christianity?

Answer 1

There is NO one geographic location for a church headquarters for the Orthodox. There is the Ecumenical Patriarchate of Constantinople as a 'primatial see' if only in sentiment as the other Patriarchates have their physical locations in other cities. The various Patriarchates include a Patriarch of Antioch (Damascus Syria usually were he's located), the largest Patriarchate is Moscow, Serbs have Belgrade, Bulgarians have Sofia. There is an independent body in the USA, the Orthodox Church in America. It has a physical headquarters in Syosset Long Island, New York that will likely end up in Washington, DC. as the complexities and costs of such a move can happen. Perhaps the multiple jurisdictions is the situation that needs be corrected. However, we hold the same Faith, doctrine, dogma, and worship.
