Pope Victor I

 was the pope in the Catholic Church.

Papacy
According to an anonymous writer quoted by Eusebius, Victor excommunicated Theodotus of Byzantium for teaching that Christ was a mere man. However, he is best known for his role in the Quartodeciman controversy. Prior to his elevation, a difference in dating the celebration of the Christian Passover/Easter between Rome and the bishops of Asia Minor had been tolerated by both the Roman and Eastern churches. The churches in Asia Minor celebrated it on the 14th of the Jewish month of Nisan, the day before Jewish Passover, regardless of what day of the week it fell on, as the Crucifixion had occurred on the Friday before Passover, justifying this as the custom they had learned from the apostles; for this the Latins called them Quartodecimans. Synods were held on the subject in various parts—in Palestine under Theophilus of Caesarea and Narcissus of Jerusalem, in Pontus under Palmas, in Gaul under Irenaeus, in Corinth under its bishop, Bachillus, at Osrhoene in Mesopotamia, and elsewhere—all of which disapproved of this practice and consequently issued by synodical letters declaring that "on the Lord's Day only the mystery of the resurrection of the Lord from the dead was accomplished, and that on that day only we keep the close of the paschal fast" (Eusebius H. E. v. 23). Despite this disapproval, the general feeling was that this divergent tradition was not sufficient grounds for excommunication. Victor alone was intolerant of this difference, and severed ties with these ancient churches, whose bishops included such luminaries as Polycrates of Ephesus; in response he was rebuked by Irenaeus and others, according to Eusebius.
