Galatians 2:2

"So that I should not run or have run in vain." That is [he says], "lest I should fail to preach a full gospel. For if I have preached anything less, I have run in vain or I now run in vain."

I exhort you all, therefore, to yield obedience to the word of righteousness, and to exercise all patience, such as ye have seen [set] before your eyes, not only in the case of the blessed Ignatius, and Zosimus, and Rufus, but also in others among yourselves, and in Paul himself, and the rest of the apostles. [This do] in the assurance that all these have not run in vain, but in faith and righteousness, and that they are [now] in their due place in the presence of the Lord, with whom also they suffered. For they loved not this present world, but Him who died for us, and for our sakes was raised again by God from the dead.

Who could be so presumptuous and blind as to dare to trust his own judgment and discretion, when the vessel of election bears witness that he needs the partnership of his coapostles?

His first journey was owing to his desire to visit Peter, his second, he says, arose from a revelation of the Spirit. "And I laid before them the Gospel which I preach among the Gentiles, but privately before them who were of repute, lest by any means I should be running or had run in vain." What is this, O Paul! thou who neither at the beginning nor after three years wouldest confer with the Apostles, dost thou now confer with them, after fourteen years are past, lest thou shouldest be running in vain? Better would it have been to have done so at first, than after so many years; and why didst thou run at all, if not satisfied that thou wert not running in vain? Who would be so senseless as to preach for so many years, without being sure that his preaching was true? And what enhances the difficulty is, that he says he went up by revelation; this difficulty, however, will afford a solution of the former one. Had he gone up of his own accord, it would have been most unreasonable, nor is it possible that this blessed soul should have fallen into such folly; for it is himself who says, "I therefore so run, as not uncertainly; so fight I, as not beating the air." (1 Cor. ix: 26.) If therefore he runs, "not uncertainly," how can he say, "lest I should be running, or had run, in vain?" It is evident from this, that if he had gone up without a revelation, he would have committed an act of folly. But the actual case involved no such absurdity; who shall dare to still harbor this suspicion, when it was the grace of the Spirit which drew him? On this account he added the words "by revelation," lest, before the question was solved, he should be condemned of folly; well knowing that it was no human occurrence, but a deep Divine Providence concerning the present and future. What then is the reason of this journey of his? […]

(Chapter 2 - Verses 1, 2) Then after fourteen years, I went up again to Jerusalem with Barnabas, taking Titus along also. I went up by revelation, and I discussed with them the gospel that I preach to the Gentiles, but privately with those who seemed to be influential, so that I might not be running in vain or have run in vain. This matter arose because of false brothers secretly brought in, who slipped in to spy out our freedom that we have in Christ Jesus, so that they might bring us into slavery.

The cause of the first journey was Peter, and of the second — a revelation. And he brought Titus and Barnabas as witnesses of his preaching, that it was pleasing to the apostles. That is, the preaching of the gospel without circumcision. Why then, after …

At the beginning, when he received the Gospel, he did not go up, nor did he put this to the Apostles. For, having learned from Christ, he did not need their teaching. As the time went by, however, and while he was teaching the nations the Gospel without circumcision, some became scandalized, since those around Peter did not dismiss circumcision, whereas he was alone in dismissing it. Thus, because the Holy Spirit wished to cut out this scandal of the others, ordered him to come up with witnesses and to put it to the Apostles that he preaches without circumcision, so that they too may join him and this scandal for human beings might be dissolved.

He gives his motive when he says, "according to a revelation from God," i.e., because God revealed and commanded him to go up to Jerusalem. From this can be gathered that all the acts and movements of the apostles were according to an instinct of …

I went up - Not by any command from them, but by an express Revelation from God. And laid before them - The chief of the church in Jerusalem. The gospel which I preach among the gentiles - Acts xv, 4, touching justification by faith alone; not that they might confirm me therein, but that I might remove prejudice from them.

Peter was the apostle to them; and the ceremonial law, though dead with Christ, yet not being as yet buried, he connived at the respect kept up for it. But Paul was the apostle of the Gentiles; and, though he was a Hebrew of the Hebrews, yet he adhered to pure Christianity.

And I went up by revelation,....

This he knew was a doctrine that would be ungrateful to many there, and yet he was not afraid to own it, but in a free and friendly manner lays it open before them and leaves them to judge whether or no it was not the true gospel of Christ.

His race was the swift-running proclamation of the Gospel to the Gentiles (compare "run," Margin, for "Word . . . have free course," 2Th 3:1). His running would have been in vain, had circumcision been necessary, since he did not require it of his converts.

I went up by revelation - This either means, that he went up at that time by an express revelation from God that it was his duty to do so, made either to the Church of Antioch to send these persons to Jerusalem, or to these persons to go according to the directions of that Church; or the apostle here wishes to say, that, having received the Gospel by revelation from God, to preach Christ among the Gentiles, he went up according to that revelation, and told what God had done by him among the Gentiles: or it may refer to the revelation made to certain prophets who came to Antioch, and particularly Agabus, who signified by the Spirit that there would be a dearth; in consequence of which the disciples purposed to send relief to their poor brethren at Jerusalem.

And I went up by revelation - Not for the purpose of receiving instruction from the apostles there in regard to the nature of the Christian religion. It is to be remembered that the design for which Paul states this is, to show that he had not received the gospel from human beings. He is careful, therefore, to state that he went up by the express command of God. He did not go up to receive instructions from the apostles there in regard to his own work, or to be confirmed by them in his apostolic office, but he went to submit an important question pertaining to the church at large. In Act 15:2, it is said that Paul and Barnabas went up by the appointment of the church at Antioch. But there is no discrepancy between that account and this, for though he was designated by the church there, there is no improbability in supposing that he was directed by a special revelation to comply with their request. The reason why he says that he went up by direct revelation seems to be to show that he did not seek instruction from the apostles; he did not go of his own accord to consult with them as if he were dependent upon them; but even in a case when he went to advise with them he was under the influence of express and direct revelation, proving that he was commissioned by God as much as they were. And communicated unto them that gospel ... - Made them acquainted with the doctrines which he preached among the pagans. He stated fully the principles on which he acted; the nature of the gospel which he taught; and his doctrine about the exemption of the Gentiles from the obligations of the Law of Moses. He thus satisfied them in regard to his views of the gospel; and showed them that he understood the system of Christianity which had been revealed. […]
