Justification Before God: Under the Gospel is not of Faith and Works United

Then some men came down from Judea and were teaching the brothers, “Unless you are circumcised according to the custom of Moses, you cannot be saved.” …

For we maintain that a man is justified by faith apart from works of the law.

And if it is by grace, then it is no longer by works. Otherwise, grace would no longer be grace.

When I saw that they were not walking in line with the truth of the gospel, I said to Cephas in front of them all, “If you, who are a Jew, live like a Gentile and not like a Jew, how can you compel the Gentiles to live like Jews?” …

You who are trying to be justified by the law have been severed from Christ; you have fallen away from grace.
