Galatians 1:6-10 MSG

6 I can't believe your fickleness - how easily you have turned traitor to him who called you by the grace of Christ by embracing a variant message!
7 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.
8 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.
9 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.
10 Do you think I speak this strongly in order to manipulate crowds? Or curry favor with God? Or get popular applause? If my goal was popularity, I wouldn't bother being Christ's slave.
