Galatians 2:14

When I saw that, in this matter, they walked not uprightly Ουκ ορθοποδουσι, did not walk with a straight step, or in a plain and straight path; according to the truth of the gospel That is, according to their own knowledge of the simplicity of the true gospel doctrine; I said to Peter, before them all That is, in the hearing of Barnabas and all the Judaizers: see Paul single against Peter and all the Jews! If thou, being a Jew And having been brought by circumcision under the strongest engagements to fulfil the whole law; livest after the manner of the Gentiles Conversing and eating freely with them, as since the vision which thou sawest thou hast done; and not as do the Jews Not observing the ceremonial law, which thou knowest to be now abolished; why compellest thou the Gentiles By refusing to eat and converse freely with them, as if the distinction of meats was necessary to be observed in order to salvation, and by withdrawing thyself, and all the ministers, from them; to live as do the Jews Ιουδαιζειν, to Judaize; to keep the ceremonial law, or be excluded from church communion. What is here recorded, probably took place at the conclusion of some of their meetings for public worship; for on these occasions it was usual, after the reading of the law and the prophets, to give the assembly exhortations. Had this offence of Peter been of a private nature, undoubtedly, as duty required, Paul would have expostulated with him privately upon it, and not have brought it, at least in the first instance, before such a number of persons: but as it was a public affair, in which many persons were deeply concerned, the method Paul took was certainly most proper. And in thus openly reproving Peter, he not only acted honestly, but generously; for it would have been mean to have found fault with him behind his back, without giving him an opportunity to vindicate himself, if he could have done it. “Perhaps,” says Macknight, “Peter in this, and in a former instance, may have been suffered to fall, the more effectually to discountenance the arrogant claims of his pretended successors to supremacy and infallibility.”
