16 It is not necessary for us to relate the whole history of the synod, but we will touch only on the principal points which served to place the truth in full light and to foster the cause of religion. Therefore, since it concerns the dignity of the Apostolic See, we must mention canon XXVIII of this council, by which the next place of honor after the Roman see was granted to Constantinople, as the imperial city. Although there was nothing in this against the divine primacy of jurisdiction of the see of Peter, which indeed was taken for granted, nevertheless, this canon was passed in the absence of the papal legates, and they subsequently objected to it. It was therefore clandestine, surreptitious and lacking in all force of law and, as such, condemned by St. Leo in many letters. Marcian and Pulcheria accepted this rescissory sentence, and even Anatolius wrote to St. Leo excusing his blameworthy boldness: 'With regard to the decree laid down by the recent synod of Chalcedon on behalf of the see of Constantinople, let your Beatitude rest assured that this was not my fault. But it was the desire of the reverend clergy of Constantinople . . . the validity and confirmation of this action being reserved to the authority of your Beatitude' (Anatolius to St. Leo the Great. Ep . cxxxii, 4. PL . liv, 1084. Mansi vi, 278S).
