Thematic Bible: Those that preach other gospels

I am astonished that you are so quickly removed from him who called you in the grace of Christ into another gospel; which is not another: but there are certain ones who are troubling you, and wishing to pervert the gospel of Christ. But indeed if we, or an angel from heaven, may preach unto you any other gospel except that which we have preached unto you, let him be accursed. read more.
As we have before said, and now again I tell you, If any one preaches to you a gospel except that which you have received, let him be accursed. For must I now believe men, or God? whether do I seek to please men? if I were still pleasing men, I would not be the servant of Christ.
