Galatians 1:7-9

1:7 not that there really is another gospel, but there are some who are disturbing you and wanting to distort the gospel of Christ. 1:8 But even if we (or an angel from heaven) should preach a gospel contrary to the one we preached to you, let him be condemned to hell! 1:9 As we have said before, and now I say again, if any one is preaching to you a gospel contrary to what you received, let him be condemned to hell!
