John Chrysostom
Catena Aurea · Markusevangelium 1
And there came a leper to him, beseeching him, and kneeling down to him, and saying unto him, If thou wilt, thou canst make me clean. And Jesus, moved with compassion, put forth his hand, and touched him, and saith unto him, I will; be thou clean. And as soon as he had spoken, immediately the leprosy departed from him, and he was cleansed. And he straitly charged him, and forthwith sent him away; And saith unto him, See thou say nothing to any man: but go thy way, shew thyself to the Priest, and offer for thy cleansing those things which Moses commanded, for a testimony unto them. But he went out, and began to publish it much, and to blaze abroad the matter, insomuch that Jesus could no more openly enter into the city, but was without in desert places: and they came to him from every quarter.
(Hom. 25. in Matt) Further, the reason why He touches the leper, and did not confer health upon him by word alone, was, that it is said by Moses in the Law, that he who touches a leper, shall be unclean till the evening; that is, that he might shew, that this uncleanness is a natural one, that the Law was not laid down for Him, but on account of mere men. Furthermore, He shews that He Himself is the Lord of the Law; and the reason why He touched the leper, though the touch was not necessary to the working of the cure, was to shew that He gives health, not as a servant, but as the Lord.
