Galatians 2:11-14

Paul Rebukes Peter

2:11 But when Cephas came to Antioch, I opposed him to his face, because he had clearly done wrong. 2:12 Until certain people came from James, he had been eating with the Gentiles. But when they arrived, he stopped doing this and separated himself because he was afraid of those who were pro-circumcision. 2:13 And the rest of the Jews also joined with him in this hypocrisy, so that even Barnabas was led astray with them by their hypocrisy. 2:14 But when I saw that they were not behaving consistently with the truth of the gospel, I said to Cephas in front of them all, “If you, although you are a Jew, live like a Gentile and not like a Jew, how can you try to force the Gentiles to live like Jews?”
