Galatians 5:2–4

2 Look: I, Paul, say to you that xif you accept circumcision, yChrist will be of no advantage to you. 3 I testify again to every man who accepts circumcision that zhe is obligated to keep the whole law. 4 You are asevered from Christ, byou who would be justified1 by the law; cyou have fallen away from grace.
