Galatians 2:13

9 And recognizing the grace that I had been given, James, Cephas, and John—those reputed to be pillars—gave me and Barnabas the right hand of fellowship, so that we should go to the Gentiles, and they to the circumcised.

10 They only asked us to remember the poor, the very thing I was eager to do.

11 When Cephas came to Antioch, however, I opposed him to his face, because he stood to be condemned.

12 For before certain men came from James, he used to eat with the Gentiles. But when they arrived, he began to draw back and separate himself, for fear of those in the circumcision group.

13 The other Jews joined him in his hypocrisy, so that by their hypocrisy even Barnabas was led astray.

14 When I saw that they were not walking in line with the truth of the gospel, I said to Cephas in front of them all, “If you, who are a Jew, live like a Gentile and not like a Jew, how can you compel the Gentiles to live like Jews?”

15 We who are Jews by birth and not Gentile “sinners”

16 know that a man is not justified by works of the law, but by faith in Jesus Christ. So we, too, have believed in Christ Jesus, that we may be justified by faith in Christ and not by works of the law, because by works of the law no one will be justified.

17 But if, while we seek to be justified in Christ, we ourselves are found to be sinners, does that make Christ a minister of sin? Certainly not!
