Galatians 2:14-16

Mace(i) 14 but when I saw, they conformed not their conduct to the truth of the gospel, I said to Peter before them all: if you being a Jew, live after the manner of the Gentiles, and not according to that of the Jews, why do you constrain the Gentiles to judaize? 15 We are Jews by birth, and not of the sinful race of the Gentiles, 16 yet knowing that a man is not justified by the works of the law, but by faith in Jesus Christ, even we have believed in Christ Jesus, that we might be justified by faith in him, and not by the works of the law, by which there is no justification.
