But when Cephas came up to Antioch, I opposed him to his face, because he stood condemned. For prior to the entrance of some men from James he was accustomed to eating with the Gentiles, but when they came, he began to pull back and hold himself separate, fearing those of the circumcision. And the rest of the Jews joined him, so that even Barnabas was carried away with them into hypocrisy. But when I saw that they were not behaving consistently with the truth of the gospel, I said to Cephas in the presence of all, "If you being a Jew, live as the Gentiles and no longer live as the Jews, how is it that you compel the Gentiles to Judaize?
We, by nature Jews and not sinners of the Gentiles, knowing that a human of the deeds required by the Law is not justified except through Jesus Christ’s faithfulness, we also believed in Christ Jesus in order that we might be justified from Christ’s faithfulness and not from the deeds required by the law, because no flesh shall be justified from the deeds required by the law.
If while we seek to be justified in Christ we are found also to be sinners, then is Christ the servant of sin? No way! For if I build again what I destroyed, I prove myself to be a transgressor. For through the law I died to the law, in order that I might live to God. I have been crucified with Christ, and I no longer live, but Christ lives in me. And the life I now live in the flesh, I live by the faithfulness that belongs to the Son of God, who loved me and gave himself on my behalf. I do not nullify God’s grace. For if righteousness comes through the law, then Christ died gratuitously."
Use of the expression, "Gentile sinners," underscores the likelihood of my suggestion. It would have been a fitting stinging expression for Paul to use in his public rebuke of Peter in the presence of Jews and Gentiles alike in Antioch. Paul's use of the expression lays bare the implicit posture that Peter exhibited toward the Gentiles who were present as he withdrew from them to eat with Jews alone."
Also, it seems to me that we need to have a deep sense of the power of intimidation that was at work so as to seduce Peter away from his heavenly-vision-transformed-posture toward Gentiles who believe in Jesus Christ (see Acts 10).
Does it make a difference whether we read verses 16-21 as the continuation of Paul's public speech to Peter in the church at Antioch? I think it does. I think that it enhances our understanding of the text. It seems to me that it sharpens the point that Paul is making. The issue at stake is not works righteousness; the issue is the end of the Mosaic Law's jurisdiction as covenant that defines God's people, the justified people, the seed of Abraham. Who are the justified people? Who are the people who are properly identified as Abraham's seed? The faithfulness of Jesus Christ is the all-essential feature that at once brings the Law of Moses to its terminus and inaugurates the new identifying feature of Abraham's seed because the faithfulness of Jesus Christ is the warrant, the ground, the basis upon which the justified people stand acquitted and declared righteous before God. It is not the Law Covenant (from the deeds required by the Law) that anyone stands justified before God. Rather, it is from the faithfulness of Jesus Christ that we find ourselves justified before God. Must we do anything to be justified? Yes. We must believe in Christ Jesus in order that we might be justified from Christ's faithfulness.
Ponder for a moment a segment of verse 16.
We, by nature Jews and not sinners of the Gentiles, know that a human of the deeds required by the Law is not justified except through Jesus Christ’s faithfulness. We also believed in Christ Jesus in order that we might be justified from Christ’s faithfulness and not from the deeds required by the law, because no flesh shall be justified from the deeds required by the law.
In particular, let's consider the force of Paul's words "we know that ἄνθρωπος ἐξ ἔργων νόμου is not justifed ἐὰν μὴ through the faithfulness of Christ Jesus." Concerning ἄνθρωπος ἐξ ἔργων νόμου, most translations separate ἄνθρωπος from its genitive modifier ἐξ ἔργων νόμου and read something like this: "We know that a man is not justified from the deeds required by the law." As such, the genitive, ἐξ ἔργων νόμου, is taken to modify the negated verb, "not justified." It seems to me that ἄνθρωπος should be viewed as modified by the genitive ἐξ ἔργων νόμου with the sense that the phrase--"a man of the works required by the Law"--is descriptive of any Jew, who by birth, is subject to the Law. Concerning ἐὰν μὴ, I would take it in its normal sense and force as "except" or "unless." Thus, the translation would be, "We know that a man of the deeds required by the Law is not justified except through the faithfulness of Jesus Christ." In other words, no Jew is justified before God in any way other than the same way that the Gentiles are justified.
Paul's argument has a force similar to the argument that Peter makes before the Council in Jerusalem when he contends:
Now therefore why are you putting God to the test by placing on the neck of the disciples a yoke that neither our ancestors nor we have been able to bear? On the contrary, we believe that we will be saved through the grace of the Lord Jesus, just as they will” (Acts 15:10-11).
The point of reference, in both Paul's and Peter's arguments, shifts to the Gentiles. As Peter makes his argument, notice how he shifts the point of reference to the Gentiles when he says, "On the contrary, we believe that we will be saved through the grace of the Lord Jesus, just as they [the Gentiles] will." As Paul makes his argument, observe how he shifts the point of reference to the Gentiles when he says, "We [Jews] . . . knowing that a man of the deeds required by the Law is not justified except through the faithfulness of Jesus Christ, we also believed in Christ Jesus in order that we might be justified from Christ’s faithfulness and not from the deeds required by the law, because no flesh shall be justified from the deeds required by the law." The Law of Moses offers absolutely nothing to a man's right standing before God. Whether one is of the deeds required by the Law (i.e., a Jew whose whole life is circumscribed by the Law of Moses) or one is a sinner of the Gentiles, what counts with regard to justification before God is the faithfulness of Jesus Christ.
