John Chrysostom, on Acts 8:30

“And Philip running thither, heard him reading the prophet Isaias. And he said: Thinkest thou that thou understandest what thou readest?”

“Observe the wisdom of Philip: he did not accuse him, not say, "I know these things exactly:" did not pay court to him, and say, "Blessed art thou that readest." But mark his speech, how far it is from harshness alike and from adulation; the speech rather of a kind and friendly man. "Understandest thou what thou readest?" For it was needful that he should himself ask, himself have a longing desire. He plainly intimates, that he knows that the other knew nothing: and says, "Understandest thou what thou readest?" at the same time he shows him that great was the treasure that lay therein.”
