He doesn't use "First Among Equals" directly, but it is used in all of the Ecumenical Patriarchate (and all EP eparchies) promotional information, usually coupled with "the spiritual leader of the world's 300 [though I think 270 is a closer figure] million Orthodox Christians." PLEASE, I DIDN'T WRITE THIS TO CAUSE A DEBATE ABOUT THIS QUOTED TERMINOLOGY AND THEREBY DIVERGE FROM THE TOPIC! I'M WELL AWARE OF HOW HOTLY DISPUTED THIS TERMINOLOGY IS WITHIN THE CHURCH, ESPECIALLY ON INTERNET FORUMS. Neither does he or the EP use "protos," or "primus," the "protos" issue came up in a conference with Roman Catholics about "primacy" in Eastern Orthodox ecclesiology. Typically, his correspondence uses the beautiful Byzantine script letter head with an English language translation for "Bartholomew, Archbishop of Constantinople, New Rome; and Ecumenical Patriarch, by the Grace of God." He signs his correspondence, "+Bartholomew of Constantinople," (just like any of the "equals.") Both of his predecessors employed the same practice.
The EP website notes that he is Orthodoxy's "First Among Equals," but does not note the origin of this title, which is what I am asking about in this topic.
"ialmisry," you were one of "the usual suspects" I expected to come up with the answer to my inquiry.
