21 Then after fourteen years I went up again to Jerusalem with Barnabas, and also took Titus with me. 2 And I went up by revelation, and communicated to them that gospel which I preach among the Gentiles, but privately to those who were of reputation, lest by any means I might run, or had run, in vain. 3 Yet not even Titus who was with me, being a Greek, was compelled to be circumcised. 4 And this occurred because of false brethren secretly brought in (who came in by stealth to spy out our liberty which we have in Christ Jesus, that they might bring us into bondage), 5 to whom we did not yield submission even for an hour, that the truth of the gospel might continue with you. 6 But from those who seemed to be something--whatever they were, it makes no difference to me; God shows personal favoritism to no man--for those who seemed to be something added nothing to me. 7 But on the contrary, when they saw that the gospel for the uncircumcised had been committed to me, as the gospel for the circumcised was to Peter 8 (for He who worked effectively in Peter for the apostleship to the circumcised also worked effectively in me toward the Gentiles), 9 and when James, Cephas, and John, who seemed to be pillars, perceived the grace that had been given to me, they gave me and Barnabas the right hand of fellowship, that we should go to the Gentiles and they to the circumcised. 10 They desired only that we should remember the poor, the very thing which I also was eager to do.

Paul Rebukes Peter at Antioch

11 Now when Peter had come to Antioch, I withstood him to his face, because he was to be blamed; 12 for before certain men came from James, he would eat with the Gentiles; but when they came, he withdrew and separated himself, fearing those who were of the circumcision. 13 And the rest of the Jews also played the hypocrite with him, so that even Barnabas was carried away with their hypocrisy. 14 But when I saw that they were not straightforward about the truth of the gospel, I said to Peter before them all, "If you, being a Jew, live in the manner of Gentiles and not as the Jews, why do you [1] compel Gentiles to live as Jews?

Commentary on Galatians 2:1-10

(Read Galatians 2:1-10)

Observe the apostle's faithfulness in giving a full account of the doctrine he had preached among the Gentiles, and was still resolved to preach, that of Christianity, free from all mixture of Judaism. This doctrine would be ungrateful to many, yet he was not afraid to own it. His care was, lest the success of his past labours should be lessened, or his future usefulness be hindered. While we simply depend upon God for success to our labours, we should use every proper caution to remove mistakes, and against opposers. There are things which may lawfully be complied with, yet, when they cannot be done without betraying the truth, they ought to be refused. We must not give place to any conduct, whereby the truth of the gospel would be reflected upon. Though Paul conversed with the other apostles, yet he did not receive any addition to his knowledge, or authority, from them. Perceiving the grace given to him, they gave unto him and Barnabas the right hand of fellowship, whereby they acknowledged that he was designed to the honour and office of an apostle as well as themselves. They agreed that these two should go to the heathen, while they continued to preach to the Jews; judging it agreeable to the mind of Christ, so to divide their work. Here we learn that the gospel is not ours, but God's; and that men are but the keepers of it; for this we are to praise God. The apostle showed his charitable disposition, and how ready he was to own the Jewish converts as brethren, though many would scarcely allow the like favour to the converted Gentiles; but mere difference of opinion was no reason to him why he should not help them. Herein is a pattern of Christian charity, which we should extend to all the disciples of Christ.

Commentary on Galatians 2:11-14

(Read Galatians 2:11-14)

Notwithstanding Peter's character, yet, when Paul saw him acting so as to hurt the truth of the gospel and the peace of the church, he was not afraid to reprove him. When he saw that Peter and the others did not live up to that principle which the gospel taught, and which they professed, namely, That by the death of Christ the partition wall between Jew and Gentile was taken down, and the observance of the law of Moses was no longer in force; as Peter's offence was public, he publicly reproved him. There is a very great difference between the prudence of St. Paul, who bore with, and used for a time, the ceremonies of the law as not sinful, and the timid conduct of St. Peter, who, by withdrawing from the Gentiles, led others to think that these ceremonies were necessary.
