Theophylact of Bulgaria
When the Lord came to this place, a man who could not see was brought before Him. However, the belief of those who accompanied him lacked sincerity, prompting the Lord to take the man outside the village before restoring his sight. He applied saliva to the man's eyes and placed His hands upon him, demonstrating that both the divine command and the subsequent actions can bring about miraculous healing: the hand symbolizes action, while spitting represents the word as it issues forth from the mouth. Yet, the blind man did not possess perfect faith. As a result, the Lord granted him sight not all at once but in stages, reflecting the incomplete nature of his faith, for the extent of healing corresponds to the level of belief.
