St. Mark recounts that the Lord was moved with compassion for the leper (see Mk. 1:41), which is a beautiful expression. The Evangelists often emphasize this to reinforce our faith and lead us to emulate such actions: to bolster our belief, they narrate miraculous events; to inspire imitation, they highlight righteous acts. The Lord reaches out and touches the leper without disdain, giving the command unhesitatingly; in this, His authority shines forth, for with the ability to heal and command, He does not shy away from demonstrating His power through action. "I will," He states, countering Photinus; He commands, contradicting Arius; He touches, opposing the Manichaeans. Moreover, not only one person is cleansed from leprosy, but all whom the words reach: "You have already been cleansed through the word which I preached to you" (John 15:3). If the cleansing of leprosy is accomplished by the Word, then disregarding the Word results in the leprosy of the soul.
It is likewise remarkable that He healed exactly as He was requested. "If you are willing, you can make me clean." "I am willing," He responded, "be cleansed" (Luke 5:12-13). Here is His will, displaying His gracious intent: He extended His hand and touched him (Lk. 5:13). While the law prohibits touching lepers, the Lord of the law does not adhere to it in a conventional sense but rather fulfills and establishes the law. Therefore, He touched not out of necessity to heal, but to reveal that He is not bound by the law and is unafraid of contagion like mere mortals. From His touch, the leprosy, which typically would afflict the one who touches, departed, because the Lord, who liberates others from impurity, cannot be tainted Himself.
