Galatians 1:6-10

I am astonished and extremely irritated that you are so quickly shifting your allegiance and deserting Him who called you by the grace of Christ, for a different [even contrary] gospel; which is really not another [gospel]; but there are [obviously] some [people masquerading as teachers] who are disturbing and confusing you [with a misleading, counterfeit teaching] and want to distort the gospel of Christ [twisting it into something which it absolutely is not]. But even if we, or an angel from heaven, should preach to you a gospel contrary to that which we [originally] preached to you, let him be condemned to destruction! As we have said before, so I now say again, if anyone is preaching to you a gospel different from that which you received [from us], let him be condemned to destruction! Am I now trying to win the favor and approval of men, or of God? Or am I seeking to please someone? If I were still trying to be popular with men, I would not be a bond-servant of Christ.
