7 not that there is another one, but there are some who trouble 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 the one we preached to you, let him be accursed.
9 As we have said before, so now I say again: If anyone is preaching to you a gospel contrary to the one you received, let him be accursed.
10 For am I now seeking the approval of man, or of God? Or am I trying to please man? If I were still trying to please man, I would not be a servant of Christ.
11 For I would have you know, brothers, that the gospel that was preached by me is not man’s gospel.
12 For I did not receive it from any man, nor was I taught it, but I received it through a revelation of Jesus Christ.
13 For you have heard of my former life in Judaism, how I persecuted the church of God violently and tried to destroy it.
