I'm amazed that you are so quickly deserting the one who called you by the grace of Christ to follow another gospel.
References for Galatians 1:6
It's not really another gospel, but certain people are confusing you and they want to change the gospel of Christ.
However, even if we ourselves or a heavenly angel should ever preach anything different from what we preached to you, they should be under a curse.
I'm repeating what we've said before: if anyone preaches something different from what you received, they should be under a curse!
