Catena Aurea · Lukasevangelium 5
And it came to pass, when he was in a certain city, behold a man full of leprosy: who seeing Jesus fell on his face, and besought him, saying, Lord, if thou wilt, thou canst make me clean. And he put forth his hand, and touched him, saying, I will: be thou clean. And immediately the leprosy departed from him. And he charged him to tell no man: but go, and shew thyself to the Priest, and offer for thy cleansing, according as Moses commanded, for a testimony unto them. But so much the more went there a fame abroad of him: and great multitudes came together to hear, and to be healed by him of their infirmities. And he withdrew himself into the wilderness, and prayed.
He heals in the same manner in which He had been entreated to heal, as it follows, And Jesus put forth his hand, and touched him, &c. The law forbids to touch the leprous man, but He who is the Lord of the law submits not to the law, but makes the law; He did not touch because without touching He was unable to make him clean, but to shew that he was neither subject to the law, nor feared the contagion as man; for He could not be contaminated Who delivered others from the pollution. On the other hand, He touched also, that the leprosy might be expelled by the touch of the Lord, which was wont to contaminate him that touched.
