Fourteen years later Paul went up again to Jerusalem with Barnabas, taking Titus, a Greek, along. He went because of a revelation and laid before the leaders, in private, the gospel he preached among the Gentiles. Titus was not compelled to be circumcised, even though false brothers, brought in secretly to spy on the freedom believers have in Christ and enslave them, demanded it. Paul did not yield even for a moment, so that the truth of the gospel might remain with the Galatians.
Those who seemed to be pillars, James, Cephas and John, added nothing to his message. They recognized that Paul had been entrusted with the gospel for the uncircumcised, just as Peter was for the circumcised, and gave him and Barnabas the right hand of fellowship. They asked only that they remember the poor, which Paul was eager to do.
When Cephas came to Antioch, Paul opposed him to his face because he stood condemned. Before certain men came from James, Cephas ate with the Gentiles; when they arrived, he drew back for fear of the circumcision party. The other Jews joined him, and even Barnabas was led astray. Paul told Cephas before them all that his conduct was not in step with the truth of the gospel.
Then Paul states the gospel: we who are Jews by birth know that a person is not justified by works of the law but through faith in Jesus Christ. He has been crucified with Christ; it is no longer he who lives, but Christ who lives in him, and the life he now lives in the flesh he lives by faith in the Son of God, who loved him and gave himself for him. If righteousness came through the law, Christ died for no purpose.
