1 Corinthians 1:22

The Jews seek signs because they do not reject the possibility that things like this can happen. What they want to know is whether it has actually occurred, like Aaron's rod, which sprouted and bore fruit, and Jonah who spent three days and nights in …

Since then the man, not the god, of the world in his wisdom knew not God, whom indeed he ought to have known (both the Jew by his knowledge of the Scriptures, and all the human race by their knowledge of God's works), therefore that God, who was not acknowledged in His wisdom, resolved to smite men's knowledge with His foolishness, by saving all those who believe in the folly of the preached cross. "Because the Jews require signs," who ought to have already made up their minds about God, "and the Greeks seek after wisdom," who rely upon their own wisdom, and not upon God's. If, however, it was a new god that was being preached, what sin had the Jews committed, in seeking after signs to believe; or the Greeks, when they hunted after a wisdom which they would prefer to accept? Thus the very retribution which overtook both Jews and Greeks proves that God is both a jealous God and a Judge, inasmuch as He infatuated the world's wisdom by an angry and a judicial retribution.

Next, to shew the power of the Cross, he saith, "For Jews ask for signs and Greeks seek after wisdom: but we preach Christ crucified, unto Jews a stumbling-block, and unto Greeks foolishness; but unto them that are called, both Jews and Greeks, Christ the Power of God, and the Wisdom of God." Vast is the import of the things here spoken! For he means to say how by contraries God hath overcome, and how the Gospel is not of man. What he saith is something of this sort. When, saith he, we say unto the Jews, Believe; they answer, Raise the dead, Heal the demoniacs, Shew unto us signs. But instead thereof what say we? That He was crucified, and died, who is preached. And this is enough, not only to fail in drawing over the unwilling, but even to drive away those even who are willing. Nevertheless, it drives not away, but attracts and holds fast and overcomes. Again; the Greeks demand of us a rhetorical style, and the acuteness of sophistry. But preach we to these also the Cross, and that which in the case of the Jews seems weakness, this in the case of the Greeks is foolishness. Wherefore, when we not only fail in producing what they demand, but also produce the very opposites of their demand; (for the Cross has not merely no appearance of being a sign sought out by reasoning, but even the very annihilation of a sign;-is not merely deemed no proof of power, but a conviction of weakness;-not merely no display of wisdom, but a suggestion of foolishness;)-when therefore they who seek for signs and wisdom not only receive not the things which they ask, but even hear the contrary to what they desire, and then by means of contraries are persuaded;-how is not the power of Him that is preached unspeakable? As if to some one tempest-tost and longing for a haven, you were to shew not a haven but another wilder portion of the sea, and so could make him follow with thankfulness? […]

As, then, he who is fond of hunting captures the game after seeking, tracking, scenting, hunting it down with dogs; so truth, when sought and got with toil, appears a delicious thing. Why, then, you will ask, did you think it fit that such an arrangement should be adopted in your memoranda? Because there is great danger in divulging the secret of the true philosophy to those, whose delight it is unsparingly to speak against everything, not justly; and who shout forth all kinds of names and words indecorously, deceiving themselves and beguiling those who adhere to them. "For the Hebrews seek signs," as the apostle says, "and the Greeks seek after wisdom."

Paul wants to show how God produced opposite effects by opposite means, and says: when I tell a Jew "believe," he immediately demands signs to confirm the preaching, but we preach Christ crucified; and this not only does not show signs, but on the contrary …
