Galatians 1:6-9

6I am shocked that you are turning away so soon from God, who called you to himself through the loving mercy of Christ. You are following a different way that pretends to be the Good News

7but is not the Good News at all. You are being fooled by those who deliberately twist the truth concerning Christ.

8Let God’s curse fall on anyone, including us or even an angel from heaven, who preaches a different kind of Good News than the one we preached to you.

9I say again what we have said before: If anyone preaches any other Good News than the one you welcomed, let that person be cursed.
