Thematic Bible: Those that preach other gospels

I marvel that you are so soon removed from him that called you into the grace of Christ unto another gospel: Which is not another; but there be some that trouble you, and would pervert the gospel of Christ. 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. read more.
As we said before, so say I now again, If any man preach any other gospel unto you than that you have received, let him be accursed. For do I now seek the favor of men, or God? or do I seek to please men? for if I yet pleased men, I should not be the servant of Christ.
