Thematic Bible: Liberty being threatened by legalism

It was for freedom that Christ set us free; therefore keep standing firm and do not be subject again to a yoke of slavery. Behold I, Paul, say to you that if you receive circumcision, Christ will be of no benefit to you. And I testify again to every man who receives circumcision, that he is under obligation to keep the whole Law. read more.
You have been severed from Christ, you who are seeking to be justified by 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. You were running well; who hindered you from obeying the truth? This persuasion did not come from Him who calls you. A little leaven leavens the whole lump of dough. I have confidence in you in the Lord that you will adopt no other view; but the one who is disturbing you will bear his judgment, whoever he is. But I, brethren, if I still preach circumcision, why am I still persecuted? Then the stumbling block of the cross has been abolished. I wish that those who are troubling you would even mutilate themselves. For you were called to freedom, brethren; only do not turn your freedom into an opportunity for the flesh, but through love serve one another.
