Galatians 1:8-10

But 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! As 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! Am 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.
