Saint Paul to the Galations 1:6-10
[6] I wonder that you are so soon removed from him that called you into the grace of Christ, unto another gospel. [7] Which is not another, only there are some that trouble you, and would pervert the gospel of Christ. [8] But though we, or an angel from heaven, preach a gospel to you besides that which we have preached to you, let him be anathema. [9] As we said before, so now I say again: If any one preach to you a gospel, besides that which you have received, let him be anathema.
