Galatians 1:11

But I certify you, brethren, etc. - I wish you fully to comprehend that the Gospel which I preached to you is not after man; there is not a spark of human invention in it, nor the slightest touch of human cunning.

But I certify you - I make known to you; or, I declare to you; see 1 Corinthians 15:1. Doubtless this had been known to them before, but he now assures them of it, and goes into an extended illustration to show them that he had not received his authority from man to preach the gospel To state and prove this is the main design of this chapter.

Is not after man - The Greek text: "Not according to man"; see Galatians 1:1. That is, he was not appointed by man, nor did he have any human instructor to make known to him what the gospel was. He had neither received it from man, nor had it been debased or adulterated by any human admixtures. He had received it directly from the Lord Jesus.

1:11 But I certify you, brethren - He does not till now give them even this appellation. That the gospel which was preached by me among you is not according to man - Not from man, not by man, not suited to the taste of man.
