Galatians 2:1-14 New Revised Standard Version (NRSV)
Paul and the Other Apostles
2 Then after fourteen years I went up again to Jerusalem with Barnabas, taking Titus along with me. 2 I went up in response to a revelation. Then I laid before them (though only in a private meeting with the acknowledged leaders) the gospel that I proclaim among the Gentiles, in order to make sure that I was not running, or had not run, in vain. 3 But even Titus, who was with me, was not compelled to be circumcised, though he was a Greek. 4 But because of false believers[a] secretly brought in, who slipped in to spy on the freedom we have in Christ Jesus, so that they might enslave us— 5 we did not submit to them even for a moment, so that the truth of the gospel might always remain with you. 6 And from those who were supposed to be acknowledged leaders (what they actually were makes no difference to me; God shows no partiality)—those leaders contributed nothing to me. 7 On the contrary, when they saw that I had been entrusted with the gospel for the uncircumcised, just as Peter had been entrusted with the gospel for the circumcised 8 (for he who worked through Peter making him an apostle to the circumcised also worked through me in sending me to the Gentiles), 9 and when James and Cephas and John, who were acknowledged pillars, recognized the grace that had been given to me, they gave to Barnabas and me the right hand of fellowship, agreeing that we should go to the Gentiles and they to the circumcised. 10 They asked only one thing, that we remember the poor, which was actually what I was[b] eager to do.
Paul Rebukes Peter at Antioch
11 But when Cephas came to Antioch, I opposed him to his face, because he stood self-condemned; 12 for until certain people came from James, he used to eat with the Gentiles. But after they came, he drew back and kept himself separate for fear of the circumcision faction. 13 And the other Jews joined him in this hypocrisy, so that even Barnabas was led astray by their hypocrisy. 14 But when I saw that they were not acting consistently with the truth of the gospel, I said to Cephas before them all, “If you, though a Jew, live like a Gentile and not like a Jew, how can you compel the Gentiles to live like Jews?”[c]
