{6} But I certify you, brethren, that the gospel which was preached of me is not after man.

(6) A second argument to prove that his doctrine is heavenly, because he had it from heaven, from Jesus Christ himself, without any man's help, in which he excels those whom Christ taught here on earth after the manner of men.

People's New Testament

1:11 The gospel which was preached by me is not after to man. It is not preached to please man, nor is it of human origin.

Wesley's Notes

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.

Jamieson-Fausset-Brown Bible Commentary

11. certify-I made known to you as to the Gospel which was preached by me, that it is not after man, that is, not of, by, or from man (Ga 1:1, 12). It is not according to man; not influenced by mere human considerations, as it would be, if it were of human origin.

brethren-He not till now calls them so.

Matthew Henry's Concise Commentary

1:10-14 In preaching the gospel, the apostle sought to bring persons to the obedience, not of men, but of God. But Paul would not attempt to alter the doctrine of Christ, either to gain their favour, or to avoid their fury. In so important a matter we must not fear the frowns of men, nor seek their favour, by using words of men's wisdom. Concerning the manner wherein he received the gospel, he had it by revelation from Heaven. He was not led to Christianity, as many are, merely by education.
