8. But though we, or an angel from heaven, preach a gospel to you besides that which we have preached to you, let him be anathema.
9. As we said before, so now I say again: If any one preach to you a gospel, besides that which you have received, let him be anathema.
10. For do I now persuade men, or God? Or do I seek to please men? If I yet pleased men, I should not be the servant of Christ.
11. For I give you to understand, brethren, that the gospel which was preached by me is not according to man.
12. For neither did I receive it of man, nor did I learn it; but by the revelation of Jesus Christ.
13. For you have heard of my conversation in time past in the Jews' religion: how that, beyond measure, I persecuted the church of God, and wasted it.
14. And I made progress in the Jews' religion above many of my equals in my own nation, being more abundantly zealous for the traditions of my fathers.
15. But when it pleased him, who separated me from my mother's womb, and called me by his grace,
16. To reveal his Son in me, that I might preach him among the Gentiles, immediately I condescended not to flesh and blood.
17. Neither went I to Jerusalem, to the apostles who were before me: but I went into Arabia, and again I returned to Damascus.
18. Then, after three years, I went to Jerusalem, to see Peter, and I tarried with him fifteen days.
19. But other of the apostles I saw none, saving James the brother of the Lord.
20. Now the things which I write to you, behold, before God, I lie not.
