Galatians 1:8-10

But even though we, or an angel from heaven, should proclaim to you any “good news” other than that which we preached to you, let him be cursed. As we have said before, so I now say again: if any man preaches to you any “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 wouldn’t be a servant of Messiah.
