1 Corinthians 2:6

"Howbeit we speak wisdom among the perfect:" for when I, accounted foolish and a preacher of follies, get the better of the wise, I overcome wisdom, not by foolishness but by a more perfect wisdom; a wisdom, too, so ample and so much greater, that the other appears foolishness. Wherefore having before called it by a name such as they named it at that time, and having both proved his victory from the facts, and shewn the extreme foolishness of the other side: he thenceforth bestows upon it its right name, saying, "Howbeit we speak wisdom among the perfect." "Wisdom" is the name he gives to the Gospel, to the method of salvation, the being saved by the Cross. "The perfect," are those who believe. For indeed they are "perfect," who know all human things to be utterly helpless, and who overlook them from the conviction that by such they are profited nothing: such were the true believers. "But not a wisdom of this world." For where is the use of the wisdom which is without, terminating here and proceeding no further, and not even here able to profit its possessors? Now by the "rulers of the world," here, he means not certain demons, as some suspect, but those in authority, those in power, those who esteem the thing worth contending about, philosophers, rhetoricians and writers of speeches. For these were the dominant sort and often became leaders of the people. "Rulers of the world" he calls them, because beyond the present world their dominion extends not. Wherefore, he adds further, "which are coming to nought;" disparaging it both on its own account, and from those who wield it. For having shewn that it is false, that it is foolish, that it can discover nothing, that it is weak, he shews moreover that it is but of short duration.
