And he put forth his hand, and touched him, saying,
I will: be clean.
And immediately the leprosy departed from him.
Read Chapter 5
Cyril of Alexandria
AD 444
He accepts his petition and confesses that he is able and says, “I will; be cleansed.” He grants him also the touch of his holy and allpowerful hand. Immediately the leprosy departed from him, and his affliction was ended. Join with me, therefore, in adoring Christ, thus exercising at the same time both a divine and a bodily power. For it was a divine act so to will as for all that he willed to be present unto him. To stretch out the hand, however, was a human act. Christ, therefore, is perceived to be One of both, if, as is the case, the Word was made flesh. Commentary on Luke, Homily
Go, show yourself. This was for the sake of the priests. For the leper was afraid to touch him lest he defile him. But the Lord touched him to show him that he would not be defiled, he, at whose rebuke the defilement fled from the defiled one. Commentary on Tatian’s Diatessaron
The law forbade lepers to be touched; but he, who is the Lord of the law, dispenses with it. He touches the leper, not because he could not cleanse him without it, but in order to show that he was not subject to the law, nor to fear of any infection. At the touch of Christ leprosy is dispelled, which before communicated contagion to all that touched it. (St. Ambrose)
