Catena Aurea on John 2:18–22: John Chrysostom

But were signs necessary for His putting a stop to evil practices? Was not the having such zeal for the house of God, the greatest sign of His virtue? They did not however remember the prophecy, but asked for a sign; at once irritated at the loss of their base gains, and wishing to prevent Him from going further. For this dilemma, they thought, would oblige Him either to work miracles, or give up His present course. But He refuses to give them the sign, as He did on a like occasion, when He answers, An evil and adulterous generation seeketh after a sign, and there shall no sign he given it, but the sign of Jonas the prophet; (Mat. 12:39) only the answer is more open there than here. He however who even anticipated men’s wishes, and gave signs when He was not asked, would not have rejected here a positive request, had He not seen a crafty design in it. As it was, Jesus answered and said unto them, Destroy this temple, and in three days I will raise it up.
