Read through Galatians carefully, paying special attention to the contrast (is it contradiction?) between Paul's negative statements about the law in chapter 3 and his own (law-related) commands in 5:13-6:10. Is the law gone for the Christian (3:25) or still relevant (5:14)? Is the law of Christ (6:2) something quite different from the Mosaic Law? Try to solve the problem textually rather than philosophically.
