Certain professors of the name of Christ, of the sect of the Pharisees, came down from Judea to Antioch, and said that the Christians of the Gentiles ought to be circumcised and keep the law of Moses if they would be saved. This upset many of the brethren in Syria and Cilicia with their perverse doctrine. Both Paul and Barnabas stiffly opposed them. (ACT 15:1-2,5,23,24) Paul called them "brethren brought in unawares." (GAL 2:4) Philastrius {Philastrius, de Haeres. c.87.} and Epiphanius {Epiphanius, Heres. 28.} said that Cerinthus, who was an arch heritic, was the first to hold this opinion.
