Does Galatians chapters 2-4 say the Ten Commandments are gone?
Many Christians interpret parts of Galatians as meaning an end to the Ten Commandments and Galatians 4:9-10 as an end to fourth Commandment, the Sabbath. See Sabbath FAQ 19. The Galatians had wandered from the truth that Paul had first taught them in favour of listening to some judaizing teachers from Jerusalem who insisted that they should still be observing all the rites of the Jewish religion such as the ceremonial law and circumcision etc. These teachers taught that Paul was inferior to the other Apostles where they had come from and insisted that the Law of Moses was still binding and was necessary for justification. For detailed information please read Galatians and the law. It is also worth reading the comparison of the ceremonial law and the Ten Commandments for a better understanding of what Paul was dealing with here.
