Pseudo-Chrysostom
Catena Aurea · Markusevangelium 8
And he cometh to Bethsaida; and they bring a blind man unto him, and besought him to touch him. And he took the blind man by the hand, and led him out of the town; and when he had spit on his eyes, and put his hands upon him, he asked him if he saw ought. And he looked up, and said, I see men as trees, walking. After that he put his hands again upon his eyes, and made him look up: and he was restored, and saw every man clearly. And he sent him away to his house, saying, Neither go into the town, nor tell it to any in the town.
(Vict. Ant. e Cat. in Marc.) He spat indeed, and put His hand upon the blind man, because He wished to shew that wonderful are the effects of the Divine word added to action; for the hand is the symbol of working, but the spittle, of the word proceeding out of the mouth. Again He asked him whether he could see any thing, which He had not done in the case of any whom He had healed, thus shewing that by the weak faith of those who brought him, and of the blind man himself, his eyes could not altogether be opened. Wherefore there follows: And he looked up, and said, I see men as trees walking; because he was still under the influence of unfaithfulness, he said that he saw men obscurely.
