One of the Fathers of the Latin Church; fifth century; Pope 440-61. He was a vigorous asserter in words and in acts of the primacy of the bishop of Rome. He heard the appeal of Celidonius, bishop of Vesontio (Besancon) from the sentence of the synod of Arles deposing him, and pronounced an ecclesiastical censure on Hilarius, the bishop who had presided over the synod. His "Dogmatic Epistle to Flavianus" set forth the Catholic doctrine in opposition to the heretical teaching of Eutyches, in the form and terms ever since recognized as orthodox in the creeds. His writings consist of 96 "Sermons" or discourses, and 173 "Epistles". A treatise on "The Sacraments" and one on "The Calling of all the Nations" are appended to his undoubtedly genuine works, and attributed to him.
