11 But when Cephas came to Antioch I opposed him to his face, because he stood condemned. 12 For before certain men came from James, he ate with the Gentiles; but when they came he drew back and separated himself, fearing the circumcision party. 13 And with him the rest of the Jews acted insincerely, so that even Barnabas was carried away by their insincerity. 14 But when I saw that they were not straightforward about the truth of the gospel, I said to Cephas before them all, "If you, though a Jew, live like a Gentile and not like a Jew, how can you compel the Gentiles to live like Jews?"

Notwithstanding Peter's character, yet, when Paul saw him acting so as to hurt the truth of the gospel and the peace of the church, he was not afraid to reprove him. When he saw that Peter and the others did not live up to that principle which the gospel taught, and which they professed, namely, That by the death of Christ the partition wall between Jew and Gentile was taken down, and the observance of the law of Moses was no longer in force; as Peter's offence was public, he publicly reproved him. There is a very great difference between the prudence of St. Paul, who bore with, and used for a time, the ceremonies of the law as not sinful, and the timid conduct of St. Peter, who, by withdrawing from the Gentiles, led others to think that these ceremonies were necessary.
