The 27th canon of the Council of Chalcedon always fascinates me. It not only puts Constantinople on a par with Rome, but it lays out the reasoning why Rome was always given a primacy. It was NOT because of Matthew 16:18 or keys or Peter, it was politically the fact that Rome was the capital city, the heart of the Empire, THE city of cities for its heydey, the New York or London of Antiquity. And when Constantinople became the “new Rome” it took on a sort of co-primacy and ascendancy. It’s fascinating. Here’s the canon and keep in mind this is from an ecumenical council, not some private Orthodox bishop:
***Canon XXVIII.
Following in all things the decisions of the holy Fathers, and acknowledging the canon, which has been just read, of the One Hundred and Fifty Bishops beloved-of-God (who assembled in the imperial city of Constantinople, which is New Rome***, in the time of the Emperor Theodosius of happy memory), we also do enact and decree the same things concerning the privileges of the most holy Church of Constantinople, which is New Rome. For the Fathers rightly granted privileges to the throne of old Rome, because it was the royal city. And the One Hundred and Fifty most religious Bishops, actuated by the same consideration, gave equal privileges (ἴσα πρεσβεῖα) to the most holy throne of New Rome, justly judging that the city which is honoured with the Sovereignty and the Senate, and enjoys equal privileges with the old imperial Rome, should in ecclesiastical matters also be magnified as she is, and rank next after her; so that, in the Pontic, the Asian, and the Thracian dioceses, the metropolitans only and such bishops also of the Dioceses aforesaid as are among the barbarians, should be ordained by the aforesaid most holy throne of the most holy Church of Constantinople; every metropolitan of the aforesaid dioceses, together with the bishops of his province, ordaining his own provincial bishops, as has been declared by the divine canons; but that, as has been above said, the metropolitans of the aforesaid Dioceses should be ordained by the archbishop of Constantinople, after the proper elections have been held according to custom and have been reported to him.
