8. But even if we or an angel from heaven should preach [to you] a gospel other than the one that we preached to you, let that one be accursed!
9. As we have said before, and now I say again, if anyone preaches to you a gospel other than the one that you received, let that one be accursed!
10. Am I now currying favor with human beings or God? Or am I seeking to please people? If I were still trying to please people, I would not be a slave of Christ.
11. Now I want you to know, brothers, that the gospel preached by me is not of human origin.
12. For I did not receive it from a human being, nor was I taught it, but it came through a revelation of Jesus Christ.
13. For you heard of my former way of life in Judaism, how I persecuted the church of God beyond measure and tried to destroy it,
14. and progressed in Judaism beyond many of my contemporaries among my race, since I was even more a zealot for my ancestral traditions.
