Irenaeus writes that Cerinthus was educated in the Gnosis of the Egyptians. According to Epiphanius, Cerinthus was the instigator of trouble against the Apostles Paul and Peter at Jerusalem, and had sent out men to Antioch commanding that gentile converts must be circumcised and keep the Law, prompting the convention of the Jerusalem Council (c. 50). After these things, Epiphanius says that Cerinthus founded a school in the Roman province of Asia Minor, which at its height spread into the province of Galatia. According to Galatian tradition, Paul wrote his epistle to the Galatians against Cerinthus' followers who were troubling the church.
