In the preceding paragraph Paul has explained why he had proclaimed the bare facts regarding Christ and His crucifixion and trusted to the Cross itself to impress the Corinthians and lead them to God, and why he had resisted the temptation to appeal to the Corinthian taste for rhetoric and philosophy by exhibiting Christianity as a philosophy. He believed that where conversion was the object of preaching no method could compare in efficiency with the simple presentation of the Cross. But sometimes he found himself in circumstances in which conversion could not be his object. He was occasionally called, as preachers in our own day are regularly called, to preach to those who were already Christians. And he tells us that in these circumstances, speaking "among the perfect," or in presence of fairly mature Christians, he made no scruple of unfolding the "wisdom" or philosophy of Christ's truth. To expound the deeper truths revealed by Christ was useless or even hurtful to mere "babes" in Christ or to those who as yet were not even born again; but to the adolescent and to those who might lay claim to have attained some firm manhood of Christian character, he was forward to teach all he himself knew. These words, "Howbeit we speak wisdom among them that are perfect," he makes the text of the following paragraph, in which he proceeds to explain (1) what the wisdom is; (2) how he speaks it; (3) to whom he speaks it. I. First, the wisdom which he speaks among the perfect, though eminently deserving of the name, is not on a level with human philosophies, nor is it of a similar origin. It is not just one more added to human searches after truth. The princes of this world, its men of light and leading, have had their own theories of God and man, and yet have really "come to nought." The incompetence of the men and theories that actually control human affairs is put beyond a doubt by the crucifixion of Christ. In the person of Christ the glory of God was manifested as a glory in which man was to partake; had there been diffused among men any true perception of the real nature of God, the Crucifixion would have been an impossibility. The fact that God's incarnate glory was crucified is a demonstration of the insufficiency of all previous teaching regarding God. But the wisdom taught by Paul is not just one theory more, devised by the speculative ingenuity of man; it is a disclosure made by God of knowledge unattainable by human endeavour. The three great sources of human knowledge--seeing, hearing, and thought--alike fail here. "Eye hath not seen, ear hath not heard, it has not entered into the heart of man to conceive," this wisdom. Hitherto it has been a mystery, a thing hidden; now God has Himself revealed it.
