Galatians 1:6-9

6I marvel that you are turning away so soon from Him who called you in the grace of Christ, to a different gospel,

7which is not another; but there are some who trouble you and want to pervert the gospel of Christ.

8But even if we, or an angel from heaven, preach any other gospel to you than what we have preached to you, let him be accursed.

9As we have said before, so now I say again, if anyone preaches any other gospel to you than what you have received, let him be accursed.
