Victor was bishop of Rome from about 190 to 198. He submitted to the opinion of the episcopate in the various parts of Christendom the divergence between the Easter usage of Rome and that of the bishops of Asia. The bishops, particularly St Irenaeus of Lyons, declared themselves in favour of the usage of Rome, but refused to associate themselves with the excommunication pronounced by Victor against their Asiatic colleagues. At Rome Victor excommunicated Theodotus of Byzantium on account of his doctrine as to the person of Christ. St Jerome attributes to Victor some opuscula in Latin, which are believed to be recognized in certain apocryphal treatises of St Cyprian.
