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 2

2:12 For before that certain came from James, he did eat with the Gentiles: but when they were come, he withdrew and separated himself, fearing them which were of the circumcision.
