(c) Leo the Great, Ep. 105, ad Pulcheriam Augustam A. D. 452. (MSL, 54:997.)
Condemnation of all canons contravening those of Nicæa.
§ 3. Let him [Anatolius] know to what sort of man he has succeeded, and, expelling all the spirit of pride, let him imitate the faith of Flavian, his modesty and his humility, which raised him up even to a confessor's glory. If he will shine with his virtues, he will be praiseworthy and everywhere he will win an abundance of love, not by seeking human things, but divine favor. And by this careful course I promise that my heart will also be bound to him, and the love of this apostolic see which we have ever bestowed upon the church of Constantinople shall never be violated by any change. Because, if rulers, lacking self-restraint, fall into errors, yet the purity of the churches of Christ continues. As for the assents of bishops which are in contradiction with the regulations of the holy canons composed at Nicæa, in conjunction with your faithful race we do not recognize them, and by the authority of the blessed Apostle Peter we absolutely disannul in comprehensive terms in all cases ecclesiastical, following those laws which the Holy Ghost set forth by three hundred and eighteen bishops for the pacific observance of all priests, so that, even if a much greater number were to pass a different decree from theirs, whatever was opposed to their constitution would have to be held in no respect.
(d) Leo the Great, Ep. 106, ad Anatolium A. D. 452. (MSL, 54:1005.)
The relation of the apostolic sees to Peter.
Your purpose is in no way whatever supported by the written assent of certain bishops, given, as you allege, sixty years ago,[181] and never brought to the knowledge of the Apostolic See by your predecessors; under this project[182] which from its outset was tottering and has already collapsed, you now wish to place too late and useless props.… The rights of provincial primates may not be overthrown, nor metropolitan bishops be defrauded of privileges based on antiquity. The see of Alexandria may not lose any of that dignity which it merited through St. Mark, the evangelist and disciple of the blessed Peter, nor may the splendor of so great a church be obscured by another's clouds, when Dioscurus fell through his persistence in impiety. The church of Antioch, too, in which first, at the preaching of the blessed Apostle Peter, the Christian name arose, must continue in the position assigned to it by the Fathers, and, being set in the third place [Can. 6, Nicæa, 325, v. supra, [§ 72]], must never be lowered therefrom. For the see is one thing, and those who preside in it something different; and an individual's great honor is his own integrity.

The policy of centralization. The primates are representatives of the bishop of Rome. Anastasius was bishop of Thessalonica.
Ch. 2. Inasmuch, dear brother, as your request has been made known to us through our son Nicholas, the priest, that you also, like your predecessors, might receive from us in your turn authority over Illyricum for the observance of the rules, we give our consent, and earnestly exhort that no concealment and no negligence may be allowed in the management of the churches situated throughout Illyricum, which we commit to [pg 481] you in our stead, following the precedent of Siricius, of blessed memory, who then, for the first time acting on a fixed method, intrusted them to your last predecessor but one, Anysius, of holy memory, who had at the time well deserved of the Apostolic See, and was approved by after events, that he might render assistance to the churches situated in that province, whom he wished to keep up to the discipline.…
Ch. 5. Those of the brethren who have been summoned to a synod should attend, and not deny themselves to the holy congregation.… But if any more important question spring up, such as cannot be settled there under your presidency, brother, send your report and consult us, so that we may write back under the revelation of the Lord, of whose mercy it is that we can do aught, because He has breathed favorably upon us; that by our decision we may vindicate our right of cognizance in accordance with old-established tradition, and the respect which is due the Apostolic See; for as we wish you to exercise your authority in our stead, so we reserve to ourselves points which cannot be decided on the spot and persons who have appealed to us.[183]
