Thematic Bible: Those that preach other gospels

I marvel that you are so quickly deserting him who called you by the grace of Christ to a different "good news"; and there is not another "good news."

But even though we, or an angel from heaven, should proclaim to you a "good news" other than that which we preached to you, let him be cursed. read more.
As we have said before, so I now say again: if any man preaches to you a "good news" other than that which you received, let him be cursed. For am I now seeking the favor of men, or of God? Or am I striving to please men? For if I were still pleasing men, I would not be a servant of Christ.
