Galater 2:16

not justified by the works of the law--as the GROUND of justification. "The works of the law" are those which have the law for their object--which are wrought to fulfil the law [ALFORD]. but by--Translate, "But only (in no other way save) through faith in Jesus Christ," as the MEAN and instrument of justification. Jesus Christ--In the second case, read with the oldest manuscripts, "Christ Jesus," the Messiahship coming into prominence in the case of Jewish believers, as "Jesus" does in the first case, referring to the general proposition. justified by the faith of Christ--that is, by Christ, the object of faith, as the ground of our justification. for by the works of the law shall no flesh be justified--He rests his argument on this as an axiom in theology, referring to Psa 143:2, "Moses and Jesus Christ; The law and the promise; Doing and believing; Works and faith; Wages and the gift; The curse and the blessing--are represented as diametrically opposed" [BENGEL]. The moral law is, in respect to justification, more legal than the ceremonial, which was an elementary and preliminary Gospel: So "Sinai" (Gal 4:24), which is more famed for the Decalogue than for the ceremonial law, is made pre-eminently the type of legal bondage. Thus, justification by the law, whether the moral or ceremonial, is excluded (Rom 3:20).

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.

2:16 Jews and Gentiles alike are sinners; the Good News requires both Jews and Gentiles to acknowledge that they are sinful (see Rom 2:1-5; 3:1-20) and in need of God’s grace (Rom 3:21-26). Peter later demonstrated his agreement with this message (Acts 15:7-11).
