Galatians 1:6-10

I am amazed that you are so quickly turning away from Him who called you by the grace of Christ and are turning to a different gospel — not that there is another gospel, but there are some who are troubling you and want to change the good news about the Messiah. But even if we or an angel from heaven should preach to you a gospel other than what we have preached to you, a curse be on him! As we have said before, I now say again: If anyone preaches to you a gospel contrary to what you received, a curse be on him! For am I now trying to win the favor of people, or God? Or am I striving to please people? If I were still trying to please people, I would not be a slave of Christ.
