Galatians 2:11-16

But when Peter came to Antioch, I resisted him to his face, because he stood condemned. For before some people came from James, he ate with the Gentiles. But when they came, he drew back and separated himself, fearing those who were of the circumcision. And the rest of the Jews joined him in his hypocrisy, so that even Barnabas was carried away with their hypocrisy. But when I saw that they didn’t walk uprightly according to the truth of the Good News, I said to Peter before them all, “If you, being a Jew, live as the Gentiles do, and not as the Jews do, why do you compel the Gentiles to live as the Jews do? “We, being Jews by nature and not Gentile sinners, yet knowing that a man is not justified by the works of the law but through faith in Jesus Christ, even we believed in Christ Jesus, that we might be justified by faith in Christ and not by the works of the law, because no flesh will be justified by the works of the law.
