Galatians 1:6-12

6I marvel that ye are so quickly removing from him that called you in the grace of Christ unto a different gospel; 7which is not another gospel: only there are some that trouble you, and would pervert the gospel of Christ. 8But though we, or an angel from heaven, should preach unto you any gospel other than that which we preached unto you, let him be anathema. 9As we have said before, so say I now again, If any man preacheth unto you any gospel other than that which ye received, let him be anathema. 10For am I now seeking the favor of men, or of God? or am I striving to please men? if I were still pleasing men, I should not be a servant of Christ.

11For I make known to you, brethren, as touching the gospel which was preached by me, that it is not after man. 12For neither did I receive it from man, nor was I taught it, but it came to me through revelation of Jesus Christ.
