Galatians 1:7-10

7which is really no gospel at all. Evidently some people are throwing you into confusion and are trying to pervert the gospel of Christ. 8But even if we or an angel from heaven should preach a gospel other than the one we preached to you, let them be under God’s curse! 9As we have already said, so now I say again: If anybody is preaching to you a gospel other than what you accepted, let them be under God’s curse! 10Am I now trying to win the approval of human beings, or of God? Or am I trying to please people? If I were still trying to please people, I would not be a servant of Christ.
