Galatians 1:7 WEB

⁵  to whom be the glory forever and ever. Amen.

⁶  I marvel that you are so quickly deserting him who called you in the grace of Christ to a different gospel;

⁷  and there isn't another gospel. Only there are some who trouble you, and want to pervert the Gospel of Christ.

⁸  But even though we, or an angel from heaven, should preach to you any gospel other than that which we preached to you, let him be cursed.

⁹  As we have said before, so I now say again: if any man preaches to you any gospel other than that which you received, let him be cursed.
