The First Council of Constantinople (The Second Ecumenical Council)

“The bishop of Constantinople shall have the primacy [prerogative] of honor after the bishop of Rome, because his city is New Rome.” (The Second Ecumenical Council, Canon 3 [A.D. 381]).


“You have shown your brotherly love for us by convoking a synod in Rome, in accordance with God’s will, and inviting us to it, by means of a letter from your most God-beloved emperor, as if we were limbs of your very own…you should not now reign in isolation from us, given the complete agreement of the emperors in matters of religion. Rather, according to the word of the apostle, we should reign along with you.” (Synodal Letter to Rome).
