There are two passages in the works of Tertullian in which he attacks the bishop of Rome, e.g. De pudicitia 1.6 (though some argue that it might be a reference to the bishop of Carthage, and not of Rome) and Adversus Praxean 1.5. He does not mention the bishop by name so there is some discussion in the scholarship which bishop or bishops he had in mind. Eusebius of Caesarea in the Ecclesiastical History 5.3 mentions "the followers of Montanus, Alcibiades and Theodotus in Phrygia" whose opinions on prophecy reached Gaul and caused some confusion in the Christian communities. They then from prison wrote to Pope Eleutherus (Soter's successor) "negotiating for the peace of the churches." Eusebius suggests that it was the first time the Montanist teachings reached Rome so the Praedestinatus claim, not confirmed elsewhere, that already Soter wrote against the Montanists is dismissed. See Salmon 1882: 938. The bishop against whom Tertullian writes in Adversus Praxean is usually identified with either Eleutherius or Victor (for further references see White 2007: 175n140).
