But when I saw that they walked not uprightly according to the truth of the gospel, I said unto Peter before them all, If thou, being a Jew, livest after the manner of Gentiles, and not as do the Jews, why compellest thou the Gentiles to live as do the Jews?
But when I saw that they walked not uprightly,.... Or "did not foot it aright"; or "walked not with a right foot": they halted, as the Jews of old did, between two opinions, being partly for God, and partly for Baal; so these seemed, according to their conduct, to be partly for grace, and partly for the works of the law; they seemed to be for joining Christ and Moses, and the grace of the Gospel, and the ceremonies of the law together; they did not walk evenly, were in and out, did not make straight paths for their feet, but crooked ones, whereby the lame were turned out of the way; they did not walk in that sincerity, with that uprightness and integrity of soul, they ought to have done:
nor according to the truth of the Gospel; though their moral conversations were as became the Gospel of Christ, yet their Christian conduct was not according to the true, genuine, unmixed Gospel of Christ; which as it excludes all the works of the law, moral or ceremonial, from the business of justification and salvation, so it declares an entire freedom from the yoke of it, both to Jews and Gentiles. Now when, and as soon as this was observed, the apostle, without any delay, lest some bad consequences should follow, thought fit to make head against it, and directly oppose it:
I said unto Peter before them all. The Alexandrian copy, and others, and the Vulgate Latin, Syriac, and Ethiopic versions, read "Cephas", as before. The reproof was given personally and principally to Peter, though Barnabas and others were concerned with him, because he was the first in it, the chief aggressor, who by his example led on the rest; and this was given publicly before Barnabas, and the other Jews that dissembled with him, and for their sakes as well as his; before the Jews that came from James for their instruction and conviction, and before all the members of the church at Antioch, for the confirmation of such who might be staggered at such conduct; nor was this any breach of the rule of Christ, Matthew 28:15 for this was a public offence done before all, and in which all were concerned, and therefore to be rebuked in a public manner: and which was done in this expostulatory way,
if thou being a Jew; as Peter was, born of Jewish parents, brought up in the Jews' religion, and was obliged to observe the laws that were given to that people:
livest after the manner of Gentiles, and not as do the Jews; that is, he had done so, he had ate with the Gentiles, and as the Gentiles did, without regarding the laws and ceremonies of the Jews relating to meats and drinks; being better informed by the Spirit of God, that these things were not now obligatory upon him, even though he was a Jew, to whom these laws were formerly made:
why compellest thou the Gentiles to live as do the Jews? he asks him, with what conscience, honour, and integrity, with what consistency with his own principles and former practice, he could compel, not by force, nor, it may be, even by persuasions and exhortations, but by his example, which was very strong and powerful, the Gentiles, to whom these laws were never given, and to observe which they never were obliged; how he could, I say, make use of any means whatever to engage these to comply with Jewish rites and ceremonies. The argument is very strong and nervous; for if he, who was a Jew, thought himself free from this yoke, and had acted accordingly, then a Gentile, upon whom it was never posed, ought not to be entangled with it: and in what he had done, either he had acted right or wrong; if he had acted wrong in eating with the Gentiles, he ought to acknowledge his fault, and return to Judaism; but if right, he ought to proceed, and not by such uneven conduct ensnare the minds of weak believers.
