Luke 5:20

For this reason also He has taught us to say in prayer, "And forgive us our debts;" since indeed He is our Father, whose debtors we were, having transgressed His commandments. But who is this Being? Is He some unknown one, and a Father who gives no commandment to any one? Or is He the God who is proclaimed in the Scriptures, to whom we were debtors, having transgressed His commandment? Now the commandment was given to man by the Word. For Adam, it is said, "heard the voice of the Lord God." Rightly then does His Word say to man, "Thy sins are forgiven thee;" He, the same against whom we had sinned in the beginning, grants forgiveness of sins in the end. But if indeed we had disobeyed the command of any other, while it was a different being who said, "Thy sins are forgiven thee;" such an one is neither good, nor true, nor just. For how can he be good, who does not give from what belongs to himself? Or how can he be just, who snatches away the goods of another? And in what way can sins be truly remitted, unless that He against whom we have sinned has Himself granted remission "through the bowels of mercy of our God," in which "He has visited us" through His Son?

And therefore, when He had healed the man sick of the palsy, [the evangelist] says "The people upon seeing it glorified God, who gave such power unto men." What God, then, did the bystanders glorify? Was it indeed that unknown Father invented by the heretics? And how could they glorify him who was altogether unknown to them? It is evident, therefore, that the Israelites glorified Him who has been proclaimed as God by the law and the prophets, who is also the Father of our Lord; and therefore He taught men, by the evidence of their senses through those signs which He accomplished, to give glory to God. If, however, He Himself had come from another Father, and men glorified a different Father when they beheld His miracles, He [in that case] rendered them ungrateful to that Father who had sent the gift of healing. But as the only-begotten Son had come for man's salvation from Him who is God, He did both stir up the incredulous by the miracles which He was in the habit of working, to give glory to the Father; and to the Pharisees, who did not admit the advent of His Son, and who consequently did not believe in the remission [of sins] which was conferred by Him, He said, "That ye may know that the Son of man hath power to forgive sins." And when He had said this, He commanded the paralytic man to take up the pallet upon which he was lying, and go into his house. By this work of His He confounded the unbelievers, and showed that He is Himself the voice of God, by which man received commandments, which he broke, and became a sinner; for the paralysis followed as a consequence of sins.

Therefore, by remitting sins, He did indeed heal man, while He also manifested Himself who He was. For if no one can forgive sins but God alone, while the Lord remitted them and healed men, it is plain that He was Himself the Word of God made the Son of man, receiving from the Father the power of remission of sins; since He was man, and since He was God, in order that since as man He suffered for us, so as God He might have compassion on us, and forgive us our debts, in which we were made debtors to God our Creator.

But the Lord, wanting to save sinners, shows himself to be God both by his knowledge of secrets and by the wonder of his actions. He adds, "Which is easier, to say, 'Your sins are forgiven you,' or to say, 'Rise and walk?' " In this passage he shows the full likeness of the resurrection. Alongside of healing the wounds of body and mind, he also forgives the sins of the spirits, removes the weakness of the flesh, and thus heals the whole person. It is a great thing to forgive people's sins—who can forgive sins, but God alone? For God also forgives through those to whom he has given the power of forgiveness. Yet it is far more divine to give resurrection to bodies, since the Lord himself is the resurrection.

Mighty is the Lord who pardons one man for the good deed of another, and while he approves of the one, forgives the other his sins. Why, O man, with thee does not thy fellowman prevail, when with God a servant has both the liberty to intercede in thy behalf, and the power of obtaining what he asks? If thou despairest of the pardon of heavy sins, bring the prayers of others, bring the Church to pray for thee, and at sight of this the Lord may pardon what otherwise He might deny to thee.

(Hom. 29. in Matt.) But there was combined in this the faith also of the sufferer himself. For he would not have submitted to be let down, had he not believed.

(ubi sup.) Now if we suffer bodily, we are enough concerned to get rid of the hurtful thing; but when there has harm happened to the soul, we delay, and so are neither cured of our bodily ailments. Let us then remove the fountain of evil, and the waters of sickness will cease to flow.

(de con. Ev. lib. ii. c. 25.) But our Lord's saying, Man, thy sins are forgiven, conveys the meaning that the man had his sins forgiven him, because in that he was man, he could not say, "I have not sinned," but at the same time also, that He who forgave sins might be known to be God.

When the Savior says to him, "Man, your sins are forgiven you," he addresses this to humankind in general. For those who believe in him, being healed of the diseases of the soul, will receive forgiveness of the sins which they formerly committed. He may also mean this: "I must heal your soul before I heal your body. If this is not done, by obtaining strength to walk, you will only sin more. Even though you have not asked for this, I as God see the maladies of the soul which brought on you this disease."

When He saw their faith, He said, "Man, your sins are forgiven you." The Lord, about to cure the man of paralysis, first dissolves the bonds of sins, to show that he was condemned to the loosening of his limbs by the bonds of faults, and that the members could not be restored to health unless these were relaxed. Likewise, to that paralytic who long awaited the stirring of the water by the pool of Bethesda in vain, when he was healed by the Lord, it is said: "Behold, you are made well; sin no more, lest something worse happen to you" (John 5). And well is he whose sins are forgiven called a man, for by this very thing that he was a man, he could not say, "I have not sinned," and at the same time so that He who forgave the man might be understood as God. Indeed, we must consider how much each one's own faith is worth before God, when the faith of another was worth so much that the whole man, that is, being saved externally and internally, suddenly arose, and by the merit of others, the errors of others were forgiven.

The Lord about to cure the man of his palsy, first loosens the chains of his sins, that He may show him, that on account of the bonds of his sins, he is punished with the loosening of his joints, and that unless the former are set free, he cannot be healed to the recovery of his limbs. Hence it follows, And when he saw their faith, &c.

I could never see how one escaped the dilemma aut deus aut malus homo by confining oneself to the Synoptics. Moderns do not seem startled, as contemporaries were, by the claim Jesus there makes to forgive sins; not sins against Himself, just sins. Yet surely, if they actually met it, they would feel differently. If Dr Pittenger told me that two of his colleagues had lost him a professorship by telling lies about his character and I replied, "I freely forgive them both", would he not think this an impertinence (both in the old and in the modern sense) bordering on insanity?
