Galatians 2:11-14

(11-14) The next phase in this question was at Antioch. On his coming thither Peter was guilty of a great inconsistency. He began by eating freely with the Gentile converts, but the arrival of a party of the stricter Jews from Jerusalem was enough to make him alter his practice. He gradually withdrew and held aloof, and a number of others, including even Barnabas, followed his example. This conduct of his I openly reproved, asking him why it was that at one moment he himself did not hesitate to adopt the custom of the Gentiles, while at another he insisted upon their conforming to those of the Jews.
