21 Then after the space of fourteen years I went up again to Jerusalem with Barnabas, taking Titus with me. 2 And I went up by revelation; and I put before them the good news which I was preaching among the Gentiles, but privately before those who were of good name, so that the work which I was or had been doing might not be without effect. 3 But not even Titus who was with me, being a Greek, was made to undergo circumcision: 4 And that because of the false brothers let in secretly, who came searching out our free condition which we have in Christ Jesus, so that they might make servants of us; 5 To whom we gave way not even for an hour; so that the true words of the good news might still be with you. 6 But from those who seemed to be important (whatever they were has no weight with me: God does not take man's person into account): those who seemed to be important gave nothing new to me; 7 But, quite the opposite, when they saw that I had been made responsible for preaching the good news to those without circumcision, even as Peter had been for those of the circumcision 8 (Because he who was working in Peter as the Apostle of the circumcision was working no less in me among the Gentiles); 9 When they saw the grace which was given to me, James and Cephas and John, who had the name of being pillars, gave to me and Barnabas their right hands as friends so that we might go to the Gentiles, and they to the circumcision; 10 Only it was their desire that we would give thought to the poor; which very thing I had much in mind to do.

Paul Rebukes Peter at Antioch

11 But when Cephas came to Antioch, I made a protest against him to his face, because he was clearly in the wrong. 12 For before certain men came from James, he did take food with the Gentiles: but when they came, he went back and made himself separate, fearing those who were of the circumcision. 13 And the rest of the Jews went after him, so that even Barnabas was overcome by their false ways. 14 But when I saw that they were not living uprightly in agreement with the true words of the good news, I said to Cephas before them all, If you, being a Jew, are living like the Gentiles, and not like the Jews, how will you make the Gentiles do the same as the 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.
