John Chrysostom — as excerpted in the Catena Aurea on Matthew 27:45-50

“Or otherwise; The wonder was in this, that the darkness was over the whole earth, which had never come to pass before, save only in Egypt what time the Passover was celebrated; for the things done then were a type of these. And consider the time when this is done; at mid-day, while over the whole world it was day, that all the dwellers on the earth might perceive it. This is the sign He promised to them that asked Him, An evil and adulterous generation seeketh a sign, and there shall no sign be given it save the sign of Jonas the Prophet, (Matt. 12:39.) alluding to His cross and resurrection. And it was a much greater marvel that this should come to pass when He was fastened to the cross, than when He was walking at large on the earth. Surely here was enough to convert them, not by the greatness of the miracle alone, but because it was done not till after all these instances of their frenzy, when their passion was past, when they had uttered all that they would, and were satiated with taunts and gibes. But how did they not all marvel and conclude Him to be God? Because the human race was at that time plunged in exceeding sluggishness and vice, and this wonder was but one, and quickly past away, and none cared to search out its cause, or perhaps they attributed it to eclipse, or some other physical consequence. And on this account He shortly afterwards lifts up His voice to shew that He yet lives, and Himself wrought this miracle; And about the ninth hour Jesus cried with a loud voice, &c.”
