[ROMANS 7:27] It is possible to neglect so weighty a command as circumcision- and fulfill the law; it is possible to observe the letter of the law, including circumcision- and transgress the law. This is not rabbinic Judaism, or any other orthodox kind of Judaism. Paul's new Christian conviction, that Jesus, whom the law had cast out, crucified, and cursed, was the risen Lord in heaven, led him to a revaluation of religion, and in particular of the law, the basis of his own national religion, far more radical than is often perceived. He not merely had a new faith, and a new theology; in the light of these he came to the conclusion that the old faith- the Old Testament and Judaism- meant something different from what he had thought.
