1 Corinthians 2:1

What Paul calls the testimony here is God the Word incarnate, hidden from all ages with God. Heretics played fast and loose with these things. They preached their wicked doctrine with great eloquence, following the wisdom of the world. They emptied Christ's cross of its power. They were embarrassed to be ridiculed by the world.

Nothing was ever more prepared for combat than the spirit of Paul; or rather, I should say, not his spirit, (for he was not himself the inventor of these things,) but, nothing was ever equal to the grace working within him, which overcometh all things. For sufficient indeed is what had been said before to cast down the pride of the boasters about wisdom; nay, even a part of it had been enough. But to enhance the splendor of the victory, he contends anew for the points which he had been affirming; trampling upon the prostrate foe. Look at it in this way: He had brought forward the prophecy which saith, "I will destroy the wisdom of the wise." He had shewn the wisdom of God, in that by means of what seemed to be foolishness, He destroyed the philosophy of the Gentiles; he had shewn that the "foolishness of God is wiser than men;" he had shewn that not only did He teach by untaught persons, but also chose untaught persons to learn of Him. Now he sheweth that both the thing itself which was preached, and the manner of preaching it, were enough to stagger people; and yet did not stagger them. As thus: "not only," saith he, "are the disciples uneducated, but I myself also, who am the preacher." Therefore he saith, "And I, brethren," (again he useth the word "brethren," to smooth down the harshness of the utterance,) "came not with excellency of speech, declaring unto you the testimony of God." "What then? tell me, hadst thou chosen to come 'with excellency,' wouldest thou have been able?" "I, indeed, had I chosen, should not have been able; but Christ, if He had chosen, was able. But He would not, in order that He might render His trophy more brilliant." Wherefore also in a former passage, shewing that it was His work which had been done, His will that the word should be preached in an unlearned manner, he said, "For Christ sent me not to baptize, but to preach the Gospel; not with wisdom of words." But far greater, yea, infinitely greater, than Paul's willing this, is the fact that Christ willed it. "Not therefore," saith he, "by display of eloquence, neither armed with arguments from without, do I declare the testimony of God." He saith not "the preaching," but "the testimony of God;" which word was itself sufficient to withhold him. For he went about preaching death: and for this reason he added, "for I determined not to know anything among you, save Jesus…
