21 Then after a lapse of fourteen years I went up again to Jerusalem with Barnabas, taking Titus also with [me]; 2 and I went up according to revelation, and I laid before them the glad tidings which I preach among the nations, but privately to those conspicuous [among them], lest in any way I run or had run in vain; 3 (but neither was Titus, who was with me, being a Greek, compelled to be circumcised;) 4 and [it was] on account of the false brethren brought in surreptitiously, who came in surreptitiously to spy out our liberty which we have in Christ Jesus, that they might bring us into bondage; 5 to whom we yielded in subjection not even for an hour, that the truth of the glad tidings might remain with you. 6 But from those who were conspicuous as being somewhat—whatsoever they were, it makes no difference to me: God does not accept man's person; for to me those who were conspicuous communicated nothing; 7 but, on the contrary, seeing that the glad tidings of the uncircumcision were confided to me, even as to Peter that of the circumcision, 8 (for he that wrought in Peter for [the] apostleship of the circumcision wrought also in me towards the Gentiles,) 9 and recognising the grace given to me, James and Cephas and John, who were conspicuous as being pillars, gave to me and Barnabas [the] right hands of fellowship, that we [should go] to the nations, and they to the circumcision; 10 only that we should remember the poor, which same thing also I was diligent to do.

Paul Rebukes Peter at Antioch

11 But when Peter came to Antioch, I withstood him to [the] face, because he was to be condemned: 12 for before that certain came from James, he ate with [those of] the nations; but when they came, he drew back and separated himself, fearing those of [the] circumcision; 13 and the rest of the Jews also played the same dissembling part with him; so that even Barnabas was carried away too by their dissimulation. 14 But when I saw that they do not walk straightforwardly, according to the truth of the glad tidings, I said to Peter before all, If thou, being a Jew, livest as the nations and not as the Jews, how dost thou compel the nations to Judaize?

Matthew Henry's Commentary on Galatians 2:1-14

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.
