John Chrysostom

"And to him they all gave heed, saying, This (man) is the Power of God." And that was fulfilled which was spoken by Christ, "There shall come false Christs and false Prophets in My name." "And to him they had regard, because that of long time he had bewitched them with sorceries." And yet there ought to have been not one demoniac there, seeing that of a long time he had been bewitching them with sorceries: but if there were many demoniacs, many palsied, these pretences were not truth.

Bede

All listened to him from the least to the greatest, saying: This man is the power of God. This, not as an adverb of place, but as a pronoun. As if to say: This one is the power of God.
