Galatians 5
2 Ref Behold, I Paul say unto you, that, if ye receive circumcision, Christ will profit you nothing.
3 Ref Yea, I testify again to every man that receiveth circumcision, that he is a debtor to do the whole law.
4 Ref Ye are severed from Christ, ye would be justified by the law; ye are fallen away from grace.
