John 9:1

"And as Jesus passed by, He saw a man which was blind from his birth." Being full of love for man, and caring for our salvation, and desiring to stop the mouths of the foolish, He omitteth nothing of His own part, though there be none to give heed. Wherefore here, when they would not receive His sublime sayings, but said that He had a devil, and attempted to kill Him, He went forth from the Temple, and healed the blind, mitigating their rage by His absence, and by working the miracle softening their hardness and cruelty, and establishing His assertions. And He worketh a miracle which was no common one, but one which took place then for the first time. "Since the world began," saith he who was healed, "was it not heard that any man opened the eyes of one that was born blind." Some have, perhaps, opened the eyes of the blind, but of one born blind never. And that on going out of the Temple, He proceeded intentionally to the work, is clear from this; it was He who saw the blind man, not the blind man who came to Him; and so earnestly did He look upon him, that even His disciples perceived it.

(Tr. xliv. 1, 2) For the blind man here is the human race. Blindness came upon the first man by reason of sin: and from him we all derive it: i. e. man is blind from his birth.

All, certainly, that was done by our Lord Jesus Christ, both works and words, are worthy of our astonishment and admiration: His works, because they are facts; His words, because they are signs. If we reflect, then, on what is signified by the deed here done, that blind man is the human race; for this blindness had place in the first man through sin, from whom we all draw our origin, not only in respect of death, but also of unrighteousness. For if unbelief is blindness, and faith enlightenment, whom did Christ find a believer at His coming? seeing that the apostle, belonging himself to the family of the prophets, says: "And we also in times past were by nature the children of wrath, even as others." If "children of wrath," then children of vengeance, children of punishment, children of hell. For how is it "by nature," save that through the first man sinning moral evil rooted itself in us as a nature? If evil has so taken root within us, every man is born mentally blind. For if he sees, he has no need of a guide. If he does need one to guide and enlighten him, then is he blind from his birth.

Mystically, our Lord, after being banished from the minds of the Jews, passed over to the Gentiles. (non occ.). The passage or journey here is His descent from heaven to earth, where He saw the blind man, i. e. looked with compassion on the human race.
