Thematic Bible: Liberty being threatened by legalism

Christ has liberated us into freedom. Therefore stand firm and don't submit again to a yoke of slavery. Take note! I, Paul, tell you that if you get circumcised, Christ will not benefit you at all. Again I testify to every man who gets circumcised that he is obligated to keep the entire law. read more.
You who are trying to be justified by the law are alienated from Christ; you have fallen from grace! For by the Spirit we eagerly wait for the hope of righteousness from faith. For in Christ Jesus neither circumcision nor uncircumcision accomplishes anything; what matters is faith working through love. You were running well. Who prevented you from obeying the truth? This persuasion did not come from Him who called you. A little yeast leavens the whole lump of dough. In the Lord I have confidence in you that you will not accept any other view. But whoever it is who is troubling you will pay the penalty. Now brothers, if I still preach circumcision, why am I still persecuted? In that case the offense of the cross has been abolished. I wish those who are disturbing you might also get themselves castrated! For you are called to freedom, brothers; only don't use this freedom as an opportunity for the flesh, but serve one another through love.
