Galatians 1:6-9

I can’t believe how you waver—how easily you have turned traitor to him who called you by the grace of Christ by embracing an alternative message! It is not a minor variation, you know; it is completely other, an alien message, a no-message, a lie about God. Those who are provoking this agitation among you are turning the Message of Christ on its head. Let me be blunt: If one of us—even if an angel from heaven!—were to preach something other than what we preached originally, let him be cursed. I said it once; I’ll say it again: If anyone, regardless of reputation or credentials, preaches something other than what you received originally, let him be cursed.
