Church Fathers on John 9:5

The Jews having rejected Christ’s words, because of their depth, He went out of the temple, and healed the blind man; that His absence might appease their fury, and the miracle soften their hard hearts, and convince their unbelief. And as Jesus passed by, He saw a man which was blind from his birth. It is to be remarked here that, on going out of the temple, He betook Himself intently to this manifestation of His power. He first saw the blind man, not the blind man Him: and…

Mystically, our Lord, after being banished from the minds of the Jews, passed over to the Gentiles. 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.

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.
