Galatians 2:14 - Coke's Commentary on the Holy Bible

According to the truth of the gospel,— That is, "That freedom from the law of Moses, which was a part of the true doctrine of the gospel." In this sense he uses the word truth throughout the epistle; insisting on it, that this doctrine of freedom from the law of Moses was a part of the true gospel. Had this been matter only of private offence, certainly St. Paul would have known that duty required him to expostulate with St. Peter privately upon it, before he referred it to such an assembly. But as it was a public affair, in which great numbers were so sensibly affected, this method was most proper. Probably this happened after public worship; and it would seem the less surprizing, considering the conferences which used to be held in the Jewish synagogues, before the assembly was broken up. It has been very justly observed, that had any imposture been carrying on, the contention of these two great managers would probably have been an occasion of discovering it.
