8 But even if we (or an angel from heaven) should preach a gospel contrary to the one we preached to you, let him be condemned to hell!
9 As we have said before, and now I say again, if any one is preaching to you a gospel contrary to what you received, let him be condemned to hell!
10 Am I now trying to gain the approval of people, or of God? Or am I trying 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 and sisters, that the gospel I preached is not of human origin.
12 For I did not receive it or learn it from any human source; instead I received it by a revelation of Jesus Christ.
13 For you have heard of my former way of life in Judaism, how I was savagely persecuting the church of God and trying to destroy it.
14 I was advancing in Judaism beyond many of my contemporaries in my nation, and was extremely zealous for the traditions of my ancestors.
