Clement of Alexandria, on 1Cor 1:21

“For seeing that in the wisdom of God the world, by wisdom, knew not God, it pleased God, by the foolishness of our preaching, to save them that believe.”

“And if you ask the cause of their seeming wisdom, he will say, "because of the blindness of their heart;" since "in the wisdom of God," that is, as proclaimed by the prophets, "the world knew not," in the wisdom "which spake by the prophets," "Him," that is, God—"it pleased God by the foolishness of preaching"—what seemed to the Greeks foolishness—"to save them that believe. For the Jews require signs," in order to faith; "and the Greeks seek after wisdom," plainly those reasonings styled "irresistible," and those others, namely, syllogisms.”
