The gospel of the uncircumcision - The duty of preaching the gospel to the uncircumcised part of the world; that is, to the Gentiles Paul had received this as his unique office when he was converted and called to the ministry (see Acts 9:15; Acts 22:21); and they now perceived that he had been specially intrusted with this office, from the remarkable success which had attended his labors. It is evidently not meant here that Paul was to preach only to the Gentiles and Peter only to the Jews, for Paul often preached in the synagogues of the Jews, and Peter was the first who preached to a Gentile Acts 10; but it is meant that it was the main business of Paul to preach to the Gentiles, or that this was especially entrusted to him.

As the gospel of the circumcision - As the office of preaching the gospel to the Jews.

Was unto Peter - Peter was to preach principally to the circumcised Jews. It is evident that until this time Peter had been principally employed in preaching to the Jews. Paul selects Peter here particularly, doubtless because he was the oldest of the apostles, and in order to show that he was himself regarded as on a level in regard to the apostleship with the most aged and venerable of those who had been called to the apostolic office by the personal ministry of the Lord Jesus.

But contrariwise - They were so far from wishing me to alter my plan, or to introduce any thing new in my doctrine to the Gentiles, that they saw plainly that my doctrine was the same as their own, coming immediately from the same source; and therefore gave to me and to Barnabas the right hand of fellowship.

The Gospel of the uncircumcision - They saw, to their utmost satisfaction, that I was as expressly sent by God to preach the Gospel to the Gentiles, as Peter was to preach it to the Jews.

But contrariwise, when they saw that the Gospel,.... James, Cephas, and John, were so far from blaming or correcting anything in the apostle's ministry, or adding anything to it, that they highly approved of it; and as a token of their agreement with him and Barnabas, gave them the right hand of fellowship: the reasons of their so doing are inserted here, and in the following verse, and in the next to that: the reason here given is, because

they saw that the Gospel of the uncircumcision was committed unto me, as the Gospel of the circumcision was to Peter; by "the uncircumcision and circumcision" are meant the Gentiles and Jews; see Romans 2:26 by the Gospel of the one, and the Gospel of the other, two Gospels are not designed, for there is but one Gospel, and not another. Paul did not preach one Gospel unto the uncircumcised Gentiles, and Peter another to the circumcised Jews; but the same Gospel was preached by both, and is so called with respect to the different persons to whom it was preached by these apostles. The Apostle Paul was ordained a minister of the Gentiles, and he chiefly preached among them, though not to them only. Peter was principally employed among the Jews, though also as he had opportunity he sometimes preached to the Gentiles: however, the subject of both their ministrations was the Gospel, which is said to be "committed" to them, as a trust deposited in their hands, not by man, but by God; the management of which required both prudence and faithfulness, and which were eminently seen in these good stewards of the mysteries of God. This being observed by the apostles at Jerusalem, they came into an agreement that one part should discharge their ministry among the Gentiles, and the other among the Jews.

The gospel of the uncircumcision (τὸ εὐαγγέλιον τῆς ἀκροβυστίας)

The phrase only here in N.T. The gospel which was to be preached to the uncircumcised - the Gentiles. Lightfoot aptly says: "It denotes a distinction of sphere, and not a difference of type."

But contrariwise, when they saw that the gospel of the {f} uncircumcision was committed unto me, as the gospel of the circumcision was unto Peter;

(f) Among the Gentiles, as Peter had to preach it among the Jews.

2:7 When they saw. They perceived that I had been sent to the Gentiles, as Peter had the leading part in preaching to the Jews.

2:7 But when they saw - By the effects which I laid before them, Gal 2:8; Acts 15:12. That I was intrusted with the gospel of the uncircumcision - That is, with the charge of preaching it to the uncircumcised heathens.

7. contrariwise-on the contrary. So far from adding any new light to ME, THEY gave in THEIR adhesion to the new path on which Barnabas and I, by independent revelation, had entered. So far from censuring, they gave a hearty approval to my independent course, namely, the innovation of preaching the Gospel without circumcision to the Gentiles.

when they saw-from the effects which I showed them, were "wrought" (Ga 2:8; Ac 15:12).

was committed unto me-Greek, "I was entrusted with."

gospel of the uncircumcision-that is, of the Gentiles, who were to be converted without circumcision being required.

circumcision . unto Peter-Peter had originally opened the door to the Gentiles (Ac 10:1-48; 15:7). But in the ultimate apportionment of the spheres of labor, the Jews were assigned to him (compare 1Pe 1:1). So Paul on the other hand wrote to the Hebrews (compare also Col 4:11), though his main work was among the Gentiles. The non-mention of Peter in the list of names, presciently through the Spirit, given in the sixteenth chapter of Romans, shows that Peter's residence at Rome, much more primacy, was then unknown. The same is palpable from the sphere here assigned to him.

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.
