8 But if anyone, even we ourselves or an Angel from Heaven, were to preach to you a gospel other than the one that we have preached to you, let him be anathema.
9 Just as we have said before, so now I say again: If anyone has preached a gospel to you, other than that which you have received, let him be anathema.
10 For am I now persuading men, or God? Or, am I seeking to please men? If I still were pleasing men, then I would not be a servant of Christ.
11 For I would have you understand, brothers, that the Gospel which has been preached by me is not according to man.
12 And I did not receive it from man, nor did I learn it, except through the revelation of Jesus Christ.
13 For you have heard of my former behavior within Judaism: that, beyond measure, I persecuted the Church of God and fought against Her.
14 And I advanced in Judaism beyond many of my equals among my own kind, having proven to be more abundant in zeal toward the traditions of my fathers.
