Towards the end of the 2nd century, Victor, the Bishop of Rome, attempted to resolve the Quartodeciman controversy. The question was whether to celebrate Easter concurrently with the Jewish Passover, as Christians in the Roman province of Asia did, or to wait until the following Sunday, as was decreed by synods held in other Eastern provinces, such as those of Palestine and Pontus, the acts of which were still extant at the time of Eusebius, and in Rome. The pope attempted to excommunicate the churches in Asia, which refused to accept the observance on Sunday. Other bishops rebuked him for doing so. Laurent Cleenewerck comments:
