We being Jews by nature, and not sinners of the Gentiles,
Verse 15. We who are Jews by nature. It has long been a question whether this and the following verses are to be regarded as a part of the address of Paul to Peter, or the words of Paul as a part of the epistle to the Galatians. A great variety of opinion has prevailed in regard to this.
St. Paul having fully vindicated his own authority as an apostle, from the imputations of the false apostles, he comes next to vindicate his doctrine, namely, the evangelical doctrine of justification by faith in Christ, which he had formerly preached to the Galatians, and which, in his absence, the false apostles had endeavoured to subvert and overthrow, urging the strict observation of the ceremonial law...
Peter came to Antioch eating freely with Gentile believers, as the Spirit had taught him; but when Jewish Christians arrived, he withdrew, and this hypocrisy I had to oppose to his face. His fault proved plainly that he was not superior to me, and so the papacy's claim to his infallibility falls to pieces.
