Thematic Bible: Liberty being threatened by legalism

Christ has set us free in freedom; stand fast therefore, and be not held again in a yoke of bondage. Behold, I, Paul, say to you, that if ye are circumcised, Christ shall profit you nothing. And I witness again to every man who is circumcised, that he is debtor to do the whole law. read more.
Ye are deprived of all profit from the Christ as separated from him, as many as are justified by law; ye have fallen from grace. For we, by the Spirit, on the principle of faith, await the hope of righteousness. For in Christ Jesus neither circumcision has any force, nor uncircumcision; but faith working through love. Ye ran well; who has stopped you that ye should not obey the truth? The persuasibleness is not of him that calls you. A little leaven leavens the whole lump. I have confidence as to you in the Lord, that ye will have no other mind; and he that is troubling you shall bear the guilt of it, whosoever he may be. But I, brethren, if I yet preach circumcision, why am I yet persecuted? Then the scandal of the cross has been done away. I would that they would even cut themselves off who throw you into confusion. For ye have been called to liberty, brethren; only do not turn liberty into an opportunity to the flesh, but by love serve one another.
