2 Corinthians 11:12-15
12. But what I do, that I will do, that I may cut off occasion from them which desire occasion; that wherein they glory, they may be found even as we.
13. For such are false apostles, deceitful workers, transforming themselves into the apostles of Christ.
14. And no marvel; for Satan himself is transformed into an angel of light.
15. Therefore it is no great thing if his ministers also be transformed as the ministers of righteousness; whose end shall be according to their works.
Galatians 1:6-9
6. I marvel that ye are so soon removed from him that called you into the grace of Christ unto another gospel:
7. Which is not another; but there be some that trouble you, and would pervert the gospel of Christ.
8. But though we, or an angel from heaven, preach any other gospel unto you than that which we have preached unto you, let him be accursed.
9. As we said before, so say I now again, If any man preach any other gospel unto you than that ye have received, let him be accursed.
