Paul’s Vindication of His Apostleship
11 For I want you to know, brothers and sisters, that the gospel that was proclaimed by me is not of human origin;
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.
