The Orthodox Church in America
was originally founded as a mission and later became a diocese in
the Orthodox Church of Russia, uniting in its fold Orthodox Christians
of various national backgrounds and traditions. It subsequently
developed into a self-governing Metropolitanate, the Russian Orthodox
Greek Catholic Church of America. Confirmation as an Autocephalous
Church was accomplished by the action of the Patriarch and Holy
Synod of Russia on April 10, 1970. The Orthodox Church in America
was proclaimed an Autocephalous Church on October 19, 1970.
