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.
10. For do I now persuade men, or God? Or do I seek to please men? If I yet pleased men, I should not be the servant of Christ.
11. For I give you to understand, brethren, that the gospel which was preached by me is not according to man.
12. For neither did I receive it of man, nor did I learn it; but by the revelation of Jesus Christ.
