6 I am amazed that you are so quickly deserting Him who called you by the grace of Christ, for a different gospel; 7 which is really not another; only there are some who are disturbing you and want to distort the gospel of Christ. 8 But even if we, or an angel from heaven, should preach to you a gospel contrary to what we have preached to you, he is to be accursed! 9 As we have said before, so I say again now, if any man is preaching to you a gospel contrary to what you received, he is to be accursed!
11 For I would have you know, brethren, that the gospel which was preached by me is not according to man. 12 For I neither received it from man, nor was I taught it, but I received it through a revelation of Jesus Christ.
