The Primacy and Infallibility of the Roman Pontiff
[From the epistle (13) "Retro maioribus tuis" to Rufus, Bishop of Thessaly, March 11, 422]
(2) . . . To the Synod [of Corinth]. . . . . we have directed such writings that all the brethren may know. . . . . that there must be no withdrawal from our judgment. For it has never been allowed that that be discussed again which has once been decided by the Apostolic See.
