No Other Gospel
Galatians 1:6 I am astonished how quickly you are deserting the One who called you by the grace of Christ and are turning to a different gospel— 7 which is not even a gospel. Evidently some people are troubling you and trying to distort the gospel of Christ.
8 But even if we or an angel from heaven should preach a gospel contrary to the one we preached to you, let him be under a divine curse! 9 As we have said before, so now I say again: If anyone is preaching to you a gospel contrary to the one you embraced, let him be under a divine curse!
