Consider these passages from the Epistle to the Galatians:
- But when the fullness of time had come, God sent forth his Son, born of woman, born under the law, to redeem those who were under the law, so that we might receive adoption as sons. (Gal 4:4-5)
- Tell me, you who desire to be under the law, do you not listen to the law? (Gal 4:21)
- I testify again to every man who accepts circumcision that he is obligated to keep the whole law. (Gal 5:3)
The ramifications for realizing this are huge: Since the "law" Paul is opposing cannot be the "covenant of works," it logically follows that Paul's warning about getting circumcised and putting oneself "under the law" could not have been a matter of people thinking they could 'work their way to heaven'. So the Calvinist is in a bind: either equivocate by equating "law" and "covenant of works" and thus claim not everyone is under the "covenant of works," or else admit "law" is the Mosaic Law and thus deny keeping the Mosaic Law has any bearing on salvation (since that's the task of the "covenant of works").
