Galatians 1:6-12 Revised Standard Version (RSV)
There Is No Other Gospel
6 I am astonished that you are so quickly deserting him who called you in the grace of Christ and turning to a different gospel— 7 not that there is another gospel, but there are some who trouble you and want to pervert the gospel of Christ. 8 But even if we, or an angel from heaven, should preach to you a gospel contrary to that which we preached to you, let him be accursed. 9 As we have said before, so now I say again, If any one is preaching to you a gospel contrary to that which you received, let him be accursed.
10 Am I now seeking the favor of men, or of God? Or am I trying to please men? If I were still pleasing men, I should not be a servant[a] of Christ.
Paul’s Vindication of His Apostleship
11 For I would have you know, brethren, that the gospel which was preached by me is not man’s[b] gospel. 12 For I did not receive it from man, nor was I taught it, but it came through a revelation of Jesus Christ.
