Galatians 1:6-10

I marvel that you are turning away so soon from Him who called you in the grace of Christ to a different gospel, which is not a gospel. But there are some who trouble you and would pervert the gospel of Christ. Although if we or an angel from heaven preach any other gospel to you than the one we have preached to you, let him be accursed. As we said before, so I say now again: If anyone preaches any other gospel to you than the one you have received, let him be accursed. For am I now seeking the approval of men or of God? Or am I trying to please men? For if I were still trying to please men, I would not be the servant of Christ.
