Galatians 5:2-6

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.

For we, through the Spirit, by faith, are waiting for the hope of righteousness.

For in Christ Jesus neither circumcision nor uncircumcision means anything, but faith working through love.
