"Ο πρώτος μεταξύ των ίσων"
"Why would Orthodoxy think that about Rome? Real question." Because the canons of the Ecumenical Councils establish that the Bishop of Rome is the first in dignity among the Patriarchs of The Church.
FWIW:
"While many Orthodox theologians would say that not only the Bishop of Rome but all bishops are successors of Peter, yet most of them admit that the Bishop of Rome is Peter's successor in a special sense... the see of Rome also owed its primacy to the positon occupied by the city of Rome in the empire.. When hard pressed in the struggle against heretics, people felt that they could turn with confidence to the Pope

And thanks for your answer. It's been so long since anyone I was talking to cares about the canons of the Ecumenical Councils! I have to start all over again. It's like I'm a newbie!
I promised myself I'd read three books by the Pope - who writes like a German, you could use his sentences for ballast -- and then Damascene, and then I'm going to have some FUN! Should be summer by then.
