We have reason to believe that, if Peter rashly erred, he freely acknowledged his error, and honoured his reprover. Both the Epistles that bear his name, in different ways, testify to the high value which their author set upon the teaching of "our beloved brother Paul." Tradition places the two men at Rome side by side in their last days; as though even in their death these glorious Apostles should not be divided, despite the attempts of faction and mistrust to separate them.

Few incidents exhibit more strongly than this the grievous consequences that may ensue from a seemingly trivial moral error. It looked a little thing that Peter should prefer to take his meals away from Gentile company. And yet, as Paul tells him, his withdrawal was a virtual rejection of the Gospel, and imperilled the most vital interests of Christianity. By this act the Jewish Apostle gave a handle to the adversaries of the Church which they have used for generations and for ages afterwards. The dispute which it occassioned could never be forgotten. In the second century it still drew down on Paul the bitter reproaches of the Judaizing faction. And in our own day the rationalistic critics have been able to turn it to marvellous account. It supplies the corner-stone of their "scientific reconstruction" of Biblical theology. The entire theory of Baur is evolved out of Peter's blunder. Let it be granted that Peter in yielding to the "certain from James" followed his genuine convictions and the tradition of Jewish Christianity, and we see at once how deep a gulf lay between Paul and the Primitive Church. All that Paul argues in the subsequent discussion only tends, in this case, to make the breach more visible. This false step of Peter is the thing that chiefly lends a colour to the theory in question, with all the far-reaching consequences touching the origin and import of Christianity, which it involves. So long "the evil that men do lives after them"!

Paul's rebuke of his brother Apostle extends to the conclusion of the chapter. Some interpreters cut it short at the end of ver. 14; others at ver. 16; others again at ver. 18. But the address is consecutive and germane to the occasion throughout. Paul does not, to be sure, give a verbatim report, but the substance of what he said, and in a form suited to his readers. The narrative is an admirable prelude to the argument of chap. iii. It forms the transition from the historical to the polemical part of the Epistle, from the Apostle's personal to his doctrinal apology. The condensed form of the speech makes its interpretation difficult and much contested. We shall in the remainder of this Chapter trace the general course of Paul's reproof, proposing in the following Chapter to deal more fully with its doctrinal contents.

I. In the first place, Paul taxes the Jewish Apostle with insincerity and unfaithfulness toward the gospel. "I saw," he says, "that they were not holding a straight course, according to the truth of the gospel."

It is a moral, not a doctrinal aberration, that Paul lays at the door of Cephas and Barnabas. They did not hold a different creed from himself; they were disloyal to the common creed. They swerved from the path of rectitude in which they had walked hitherto. They had regard no longer to "the truth of the gospel"—the supreme consideration of the servant of Christ—but to the favour of men, to the public opinion of Jerusalem. "What will be said of us there?" they whispered to each other, "if these messengers of James report that we are discarding the sacred customs, and making no difference between Jew and Gentile? We shall alienate our Judean brethren. We shall bring a scandal on the Christian cause in the eyes of Judaism."

This withdrawal of the Jews from the common fellowship at Antioch was a public matter. It was an injury to the whole Gentile-Christian community. If the reproof was to be salutary, it must be equally public and explicit. The offence was notorious. Every one deplored it, except those who shared it, or profited by it. Cephas "stood condemned." And yet his influence and the reverence felt toward him were so great, that no one dared to put this condemnation into words. His sanction was of itself enough to give to this sudden recrudescence of Jewish bigotry the force of authoritative usage. "The truth of the gospel" was again in jeopardy. Once more Paul's intervention foiled the attempts of the Judaizers and saved Gentile liberties. And this time he stood quite alone. Even the faithful Barnabas deserted him. But what mattered that, if Christ and truth were on his side? Amicus Cephas, amicus Barnabas; sed magis amicus Veritas. Solitary amid the circle of opposing or dissembling Jews, Paul "withstood" the chief of the Apostles of Jesus "to the face." He rebuked him "before them all."

II. Peter's conduct is reproved by Paul in the light of their common knowledge of salvation in Christ.

Paul is not content with pointing out the inconsistency of his brother Apostle. He must probe the matter to the bottom. He will bring Peter's delinquency to the touchstone of the Gospel, in its fundamental principles. So he passes in ver. 15 from the outward to the inward, from the circumstances of Peter's conduct to the inner world of spiritual consciousness, in which his offence finds its deeper condemnation. "You and I," he goes on to say, "not Gentile sinners, but men of Jewish birth—yet for all that, knowing that there is no justification for man in works of law, only[53] through faith in Christ—we too put our faith in Christ, in order to be justified by faith in Him, not by works of law; for as Scripture taught us, in that way no flesh will be justified."

Paul makes no doubt that the Jewish Apostle's experience of salvation corresponded with his own. Doubtless, in their previous intercourse, and especially when he first "made acquaintance with Cephas" (ch. i. 18) in Jerusalem, the hearts of the two men had been opened to each other; and they had found that, although brought to the knowledge of the truth in different ways, yet in the essence of the matter—in respect of the personal conviction of sin, in the yielding up of self-righteousness and native pride, in the abandonment of every prop and trust but Jesus Christ—their history had run the same course, and face answered to face. Yes, Paul knew that he had an ally in the heart of his friend. He was not fighting as one that beateth the air, not making a rhetorical flourish, or a parade of some favourite doctrine of his own; he appealed from Peter dissembling to Peter faithful and consistent. Peter's dissimulation was a return to the Judaic ground of legal righteousness. By refusing to eat with uncircumcised men, he affirmed implicitly that, though believers in Christ, they were still to him "common and unclean," that the Mosaic rites imparted a higher sanctity than the righteousness of faith. Now the principles of evangelical and legal righteousness, of salvation by faith and by law-works, are diametrically opposed. It is logically impossible to maintain both. Peter had long ago accepted the former doctrine. He had sought salvation, just like any Gentile sinner, on the common ground of human guilt, and with a faith that renounced every consideration of Jewish privilege and legal performance. By what right can any Hebrew believer in Christ, after this, set himself above his Gentile brother, or presume to be by virtue of his circumcision and ritual law-keeping a holier man? Such we take to be the import of Paul's challenge in vv. 15, 16.

III. Paul is met at this point by the stock objection to the doctrine of salvation by faith—an objection brought forward in the dispute at Antioch not, we should imagine, by Peter himself, but by the Judaistic advocates. To renounce legal righteousness was in effect, they urged, to promote sin—nay, to make Christ Himself a minister of sin (ver. 17).
