Galatians 1:8 WEB

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.

¹⁰  For am I now seeking the favor of men, or of God? Or am I striving to please men? For if I were still pleasing men, I wouldn't be a servant of Christ.
