Yes, and he said:

“I, Paul, tell you that if you let yourselves be circumcised, Christ will be of no value to you at all. Again I declare to every man who lets himself be circumcised that he is obligated to obey the whole law. You who are trying to be justified by law have been alienated from Christ; you have fallen away from grace.” Galatians 5:2-4

There is not debate. It was settled long ago.
