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 gospel of Christ.
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!a9
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!b10
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.
