Galatians 5:1-4

It was for freedom that Christ set us free; therefore keep standing firm and do not be subject again to a yoke of slavery.

Look! I, Paul, tell you that if you have yourselves circumcised, Christ will be of no benefit to you.

And I testify again to every man who has himself circumcised, that he is obligated to keep the whole Law.

You have been severed from Christ, you who are seeking to be justified by the Law; you have fallen from grace.
