The Epistle of Paul the Apostle to the Galatians, written in A.D. 57 or 58, probably from Antioch, is the cornerstone of Christian freedom. In Galatians Paul tells of his own conversion and of how he stood firm in his belief that Christ was the Savior of people everywhere, not just those who observed every detail of the Jewish law.

Galatians 3

3:17 And this I say, that the covenant, that was confirmed before of God in Christ, the law, which was four hundred and thirty years after, cannot disannul, that it should make the promise of none effect.
