In the Letter to the Galatians, the apostle Paul writes:
Galatians 5:7-12: "You were running well; who hindered you from obeying the truth? 8This persuasion did not come from Him who calls you. 9A little leaven leavens the whole lump of dough. 10I 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. 11But I, brethren, if I still preach circumcision, why am I still persecuted? Then the stumbling block of the cross has been abolished. 12I wish that those who are troubling you would even mutilate themselves" (emphasis added).
These words seem a bit out of character by Paul. Do we know if there is a reason for such strong language? I believe I must be missing something.
