Paul Confronts Cephas

Paul says that when Cephas came to Antioch he opposed him openly, because his conduct had become blameworthy. Cephas had been eating with Gentiles, but fear of those from the circumcision party led him to draw back, and his withdrawal pulled other Jews, even Barnabas, into hypocrisy, so Paul confronted him for no longer walking straight with the gospel's truth.

W11hen Cephas came to Antioch, however, I opposed him to his face, because he stood condemned. 12For 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. 13The other Jews joined him in his hypocrisy, so that by their hypocrisy even Barnabas was led astray. 14When 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?”

Speaking from their shared Jewish background, Paul says that a person is not justified by works of the law but through faith in Jesus Christ, and that even Jews have believed in Christ on that basis. To seek justification in Christ does not make Christ a servant of sin, he says, but rebuilding what has been torn down only shows the builder to be the transgressor.

15We who are Jews by birth and not Gentile “sinners” 16know 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. 17But 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! 18If I rebuild what I have already torn down, I prove myself to be a lawbreaker.

Paul says that through the law he died to the law so that he might live to God. He has been crucified with Christ, so that the life now lived is lived by faith in the Son of God who loved him and gave himself for him, and to place righteousness back in the law would be to set aside grace and empty Christ's death.

19For through the law I died to the law so that I might live to God. 20I have been crucified with Christ, and I no longer live, but Christ lives in me. The life I live in the body, I live by faith in the Son of God, who loved me and gave Himself up for me. 21I do not set aside the grace of God. For if righteousness comes through the law, then Christ died for nothing.

Section summaryWhen Cephas came to Antioch, Paul opposed him because fear of the circumcision party led him to withdraw from eating with Gentiles and drew others, even Barnabas, into hypocrisy. Paul says this conduct was out of step with the gospel's truth, and from that confrontation he states the heart of his argument: justification is not by works of the law but through faith in Jesus Christ, life is now Christ's life within the believer, and to return righteousness to the law would make Christ's death empty.
Role in the chapterThis section turns narrative conflict into the letter's theological center. Table fellowship becomes the concrete place where justification by faith must be lived, not merely confessed.
