Ecumenical Patriarch of Constantinople
The Ecumenical Patriarch of Constantinople is the Archbishop of Constantinople and primus inter pares among the heads of the several autocephalous churches which compose the Eastern Orthodox Church. The ecumenical patriarch is regarded as the representative and spiritual leader of the Eastern Orthodox Christians worldwide. The term ecumenical in the title is a historical reference to the Ecumene, a Greek designation for the civilised world, i.e. the Roman Empire, and it stems from Canon 28 of the Council of Chalcedon.
