11 Later, when Peter came to Antioch, I had a face-to-face confrontation with him because he was clearly out of line. 12 Here's the situation. Earlier, before certain persons had come from James, Peter regularly ate with the non-Jews. But when that conservative group came from Jerusalem, he cautiously pulled back and put as much distance as he could manage between himself and his non-Jewish friends. That's how fearful he was of the conservative Jewish clique that's been pushing the old system of circumcision. 13 Unfortunately, the rest of the Jews in the Antioch church joined in that hypocrisy so that even Barnabas was swept along in the charade. 14 But when I saw that they were not maintaining a steady, straight course according to the Message, I spoke up to Peter in front of them all: "If you, a Jew, live like a non-Jew when you're not being observed by the watchdogs from Jerusalem, what right do you have to require non-Jews to conform to Jewish customs just to make a favorable impression on your old Jerusalem cronies?"

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death of Christ the partition wall between Jew and Gentile was taken down, and the observance of the law of Moses was no longer in force; as Peter's offence was public, he publicly reproved him.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.
