Thematic Bible: Those that preach other gospels

I marvel that you are so readily leaving Him who called you by the grace of Christ, and are adhering to a different Good News. For other "Good News" there is none; but there are some persons who are troubling you, and are seeking to distort the Good News concerning Christ. But if even we or an angel from Heaven should bring you a Good News different from that which we have already brought you, let him be accursed. read more.
What I have just said I repeat--if any one is preaching to you a Good News other than that which you originally received, let him be accursed. For is it man's favour or God's that I aspire to? Or am I seeking to please men? If I were still a man-pleaser, I should not be Christ's bondservant.
