Galatians 5:2-4

2Behold, I, Paul, say to you, that if ye are circumcised, Christ shall profit you nothing.

3And I witness again to every man [who is] circumcised, that he is debtor to do the whole law.

4Ye are deprived of all profit from the Christ as separated [from him], as many as are justified by law; ye have fallen from grace.
