Galatians 1:9-11

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. I want you to know, brothers and sisters, that the gospel I preached is not of human origin.
