Jesus answered,
Neither has this man sinned, nor his parents: but that the works of God should be made manifest in him.
All Commentaries on John 9:3 Go To John 9
George Leo Haydock
AD 1849
When Christ says that neither he nor his parents had sinned, we must not understand that he was born without original sin, nor even that he had not committed other sins. For both he and his parents had sinned; but the meaning is, that this blindness was not a penal blindness inflicted in punishment of any sin either himself or his parents had committed; but, as is afterwards subjoined, it was sent him for the manifestation of the glory of God. (St. Augustine, tract. xliv. in Joan.)
