Catena Aurea on John 9:1–7: John Chrysostom

He is not to be understood as meaning that others had become blind, in consequence of their parents’ sins: for one man cannot be punished for the sin of another. But had the man therefore suffered unjustly? Rather I should say that that blindness was a benefit to him: for by it he was brought to see with the inward eye. At any rate He who brought him into being out of nothing, had the power to make him in the event no loser by it. Some too say, that the that here, is expressive not of the cause, but of the event, as in the passage in Romans, The law entered that sin might abound; (Rom. 5:20) the effect in this case being, that our Lord by opening the closed eye, and healing other natural infirmities, demonstrated His own power.
