Luke 5:15

The authority of power in the Lord is here compared with the steadfastness of faith manifest in the leper. He fell on his face because it is a mark of humility and modesty that each feel shame for the sins of his life, but shyness did not restrict his confession. He showed the wound, he begged for the remedy, and the very confession is full of piety and faith. "If you will," it says, "you can make me clean." He conceded the power to the Lord's will. But he doubted concerning the Lord's will, not as if unbelieving in piety, but as if aware of his own impurity, he did not presume. The Lord replies to him with a certain holiness. "I will: be clean. And immediately the leprosy departed from him." For there is nothing between God's command and his work, because the work is in the command. Thus he spoke, and they came into being. You see that it cannot be doubted that the will of God is power. If, therefore, his will is power, those who affirm that the Trinity is of One will affirm that it is of one power. Thus the leprosy departed immediately. In order that you may understand the effect of healing, he added truth to the work.

He is commanded to show himself to the priest and sacrifice for his cleansing. In offering himself to the priest, the priest may understand that he was cured not by the ordinance of the law but by the grace of God above the law. When the sacrifice is performed according to Moses' precept, the Lord shows that he did not destroy the law but fulfilled it. Furthermore, by proceeding according to the law, he was seen to heal above the law those whom the remedies of the law had not healed. "For the law is spiritual," and therefore it is seen that a spiritual sacrifice is commanded.

But lest leprosy should become rife among us, let each avoid boasting after the example of our Lord's humility. For it follows, And he commanded him that he should tell it to no one, that in truth he might teach us that our good deeds are not to be made public, but to be rather concealed, that we should abstain not only from gaining money, but even favour. Or perhaps the cause of His commanding silence was that He thought those to be preferred, who had rather believed of their own accord than from the hope of benefit.

And that the Priest also should know that not by the order of the law, but by the grace of God above the law, he was cured. And since a sacrifice is commanded by the regulation of Moses, the Lord shows that He does not abrogate the law, but fulfil it. As it follows, And offer for thy cleansing according as Moses commanded.

Or because the law is spiritual He seems to have commanded a spiritual sacrifice. Hence he said, As Moses commanded. Lastly, he adds, for a testimony unto them. The heretics understand this erroneously, saying, that it was meant as a reproach to the law. But how would he order an offering for cleansing, according to Moses' commandments, if he meant this against the law?

And although the Lord in giving out remedies advised telling them to no one, instructing us to avoid pride; yet His fame flew about every where, instilling the miracle into the ears of every one, as it follows, But so much the more went there a fame abroad of him.

Though the leper was silent, the voice of the transaction itself was sufficient to publish it to all who acknowledged through him the power of the Curer.

The word about him spread all the more, and great crowds came together to hear him and to be cured of their infirmities. The complete salvation of one urges many crowds to the Lord. For, in order to show that he was healed both outwardly and inwardly, he by no means keeps silent about the benefit received or about the one from whom he received it. Rather, as Mark the Evangelist narrates, having fulfilled the duty of a herald, he immediately began to proclaim and spread the word, so much so that Jesus could no longer openly enter a city, but stayed outside in deserted places; yet people came to him from every direction (Mark 1). Therefore, it is rightly asked why the Lord commanded some things he did to be kept hidden, and they could not be hidden even for a moment. Did the eternal Son, co-eternal with the Father and the Holy Spirit, desire something that he could not accomplish in this matter? But it should be noted that our Redeemer, through his mortal body, provided us with an example in all that he did. For when performing a miracle, he ordered silence, and yet it could not be kept silent. He thereby indicated that his chosen followers, by following his examples of teaching, should indeed wish to remain hidden in their great deeds, but be revealed against their will for the benefit of others: so that it may be an example of great humility to desire their works to be hidden, and an example of great exaltation that their works cannot be hidden. Therefore, the Lord did not wish to do anything that he could not achieve, but he provided an example of what his members ought to desire and what should be done about them even against their will, by the teaching of his example.

Now the perfect healing of one brings many multitudes to the Lord, as it follows, And great multitudes came together that they should be healed. For the leprous man that he might show both his outward and inward cure, even though forbid ceases not, as Mark says, to tell of the benefit ho had received.

But the word went abroad all the more, etc. After the Evangelist has described the healing of the disease and the instruction of the one healed, here thirdly he adds the magnification of the name of Christ, so that from all these things the disciples may be confirmed in faith and love of Christ. The magnification of the name of Christ is therefore described as renowned, as fruitful, as powerful.

First, therefore, the magnification of the name of Christ is described here as renowned, when it is said: But the word went abroad all the more concerning him, namely Christ, the word of his praise with respect to his knowledge and powers. Nor is it surprising if the fame of the Master was spreading, since of his disciples it is said in the Psalm: "Their sound has gone forth into all the earth." A figure of this preceded in Judas Maccabeus, of whom it is said in 1 Maccabees 3 that "he was made like a lion in his works"; and afterwards it is added that "he was renowned even to the ends of the earth."

Then the fruitful magnification of the name of Christ is shown, when it is added: And great multitudes came together to hear: namely for the instruction of the mind, because it is written in Sirach 6: "If you love to hear, you will be wise"; and James 1: "You know, my brothers: Let every man be swift to hear."

They were also coming together on account of the cure on the part of the body; and therefore he adds: And they were healed of their infirmities. On account of which Isaiah was proclaiming in the fifty-third chapter: "Truly he himself bore our weaknesses, and he himself carried our infirmities." And therefore they were acting rightly according to the counsel of the Wise Man, Ecclesiasticus thirty-eight: "My son, in your infirmity do not despise yourself, but pray to the Lord, and he will heal you." — This therefore was the perfect benefit on the part of the soul and body, which came from the fame of the name of Christ. For Christ himself is "the power of God and the wisdom of God"; and therefore those who come to him are illuminated through wisdom and healed through power. And therefore it is said in the Psalm: "Come to him and be enlightened, and your faces shall not be confounded"; and therefore Isaiah forty-nine: "I have given you as a light to the nations, that you may be my salvation unto the end of the earth."
