Thematic Bible: Those that preach other gospels

I marvel that ye are so quickly departed from him that called you, by the grace of Christ into another gospel which is not another; but there are certain persons who trouble you, and desire to pervert the gospel of Christ. But though even we, or an angel from heaven, preach unto you another gospel, different from that which we have preached to you, let him be an anathema. read more.
As we have before spoken, and I now repeat it again, If any man preach a gospel different from that ye have received, let him be anathema. For do I now use persuasions from men, or from God? or do I seek to please men? for if I yet pleased men, I should not be the servant of Christ.
