Галатам 2:14

walked not uprightly--literally, "straight": "were not walking with straightforward steps." Compare Gal 6:16. truth of the gospel--which teaches that justification by legal works and observances is inconsistent with redemption by Christ. Paul alone here maintained the truth against Judaism, as afterwards against heathenism (Ti2 4:16-17). Peter--"Cephas" in the oldest manuscripts before . . . all-- (Ti1 5:20). If thou, &c.--"If thou, although being a Jew (and therefore one who might seem to be more bound to the law than the Gentiles), livest (habitually, without scruple and from conviction, Act 15:10-11) as a Gentile (freely eating of every food, and living in other respects also as if legal ordinances in no way justify, Gal 2:12), and not as a Jew, how (so the oldest manuscripts read, for 'why') is it that thou art compelling (virtually, by thine example) the Gentiles to live as do the Jews?" (literally, to Judaize, that is, to keep the ceremonial customs of the Jews: What had been formerly obedience to the law, is now mere Judaism). The high authority of Peter would constrain the Gentile Christians to regard Judaizing as necessary to all, since Jewish Christians could not consort with Gentile converts in communion without it.

The apostle, in this chapter, continues the relation of his past life and conduct, which he had begun in the former; and, by some further instances of what had passed between him and the other apostles, makes it appear that he was not beholden to them either for his knowledge of the gospel or his authority as an apostle, as his adversaries would insinuate; but, on the contrary, that he was owned and approved even by them, as having an equal commission with them to this office. I. He particularly informs them of another journey which he took to Jerusalem many years after the former, and how he behaved himself at that time (Gal 2:1-10). And, II. Gives them an account of another interview he had with the apostle Peter at Antioch, and how he was obliged to behave himself towards him there. From the subject-matter of that conversation, he proceeds to discourse on the great doctrine of justification by faith in Christ, without the works of the law, which it was the main design of this epistle to establish, and which he enlarges more upon in the two following chapters.

2:14-21 The actions of Peter and the others implied that faith in Christ was not enough. Paul eloquently argues against such a compromise of the truth of the gospel message, showing that the law plays no role in defining a Christian’s position before God, which is by grace through faith (Eph 2:8-9). • It is not clear where Paul’s public rebuke of Peter ends and his message to the Galatians resumes (see study note on Gal 2:16). While Paul was recounting his address to Peter, he was also speaking to the Galatians. His rebuke of Peter was also a rebuke of them (see 3:1). 2:14 By living like a Gentile—eating with Gentiles and not observing Jewish food laws—Peter communicated God’s acceptance of Gentiles on equal terms with Jews, on the basis of faith in Christ (see Acts 10:34-43; 11:17-18). • why are you now trying to make these Gentiles follow the Jewish traditions? Both Jews and Gentiles would draw this conclusion from Peter’s actions.
