“Why then, instead of saying, ‘What need is there of “signs” to check evil deeds?’ did He promise that He would give them a sign?” Because by so doing He would have the more exasperated them; but in this way He rather astonished them. Still they made no answer to this, for He seemed to them to say what was incredible, so that they did not stay even to question Him upon it, but passed it by as impossible. Yet had they been wise, though it seemed to them at the time incredible, still when He wrought His many miracles they would then have come and questioned Him, would then have intreated that the difficulty might be resolved to them; but because they were foolish, they gave no heed at all to part of what was said, and part they heard with evil frame of mind. And therefore Christ spoke to them in an enigmatical way.
