Galatians 1:6-10

⁶ I am astonished that you are so quickly deserting him who called you in the grace of Christ and are turning to a different gospel— ⁷ not that there is another one, but there are some who trouble you and want to distort the gospel of Christ. ⁸ But even if we or an angel from heaven should preach to you a gospel contrary to the one we preached to you, let him be accursed. ⁹ As we have said before, so now I say again: If anyone is preaching to you a gospel contrary to the one you received, let him be accursed. 

¹⁰ For am I now seeking the approval of man, or of God? Or am I trying to please man? If I were still trying to please man, I would not be a servant of Christ.
