Luke 5:23

Now the Pharisee, while he was doubting concerning our Lord, that He was not a prophet, pledged himself to the truth unawares, in saying—Had this man been a prophet, he would have known that this woman is a sinner. Therefore, if it should be found that our Lord knew that she was a sinner, He is, according to thy word, O Pharisee, a prophet. Our Lord, therefore, hastened to show both that she was a sinner, and that her sins were many; that the testimony of his own mouth might confute him as a liar. For he was companion of those that said: Who is able to forgive sins, but God only? For from them our Lord received testimony, that, therefore, He Who is able to forgive sins, is God. Thenceforth, then, the contention was this, that our Lord should show them whether He was able to forgive sins or no. So He speedily healed the members that were visible, that it might be made sure that He had forgiven the sins that were invisible. For our Lord cast before them the word which was expected to catch him that said it; so that when they should rush forward to catch Him by it, according to their wish, they might be caught by Him according to His wish. Fear not, My son, thy sins are forgiven thee. While they were hastening to catch Him on the charge of blasphemy, they pledged themselves unawares to the truth. For Who is able to forgive sins but God only? Accordingly, our Lord confuted them [as though saying]: "If I shall have shown that I am able to forgive sins, even though ye do not believe in Me that I am God; yet abide ye by your word, which determined that whoso forgives sins is God." Therefore that our Lord might teach them that He forgives sins, He forgave that man his hidden sin, and caused him to carry his bed openly; that by the carrying of the bed which carries [those that lie on it], they might believe in the slaying of the sin that slays.

(ubi sup.) If then you disbelieve the first, (i. e. the forgiveness of sins,) behold, I add another, seeing that I lay open your inmost thoughts. Again, another that I make whole the body of the palsied man. Hence He adds, Whether is it easier? It is very plain that it is easier to restore the body to health. For as the soul is far nobler than the body, so is the forgiveness of sins more excellent than the healing of the body. But since you believe not the former, because it is hid; I will add that which is inferior, yet more open, in order that thereby that which is secret may be made manifest. And indeed in addressing the sick man, He said not, I forgive thee thy sins, expressing His own power, but, Thy sins are forgiven thee. But they compelled Him to declare more plainly His own power to them, when He said, But that you may know.

What is easier to say, "Your sins are forgiven," or to say, "Rise and walk"? Whether the paralytic's sins were forgiven, only He who forgives them knows. But "rise and walk," both he who rises and those who see him rising can confirm. Therefore, a physical sign is performed to prove the spiritual one.

There is added thirdly the refutation of errors of those thinking wrongly, in what follows: Which is easier to say etc. For he constructs an argument in which he shows that he is true God and can forgive sins, and consequently that they err. And the argument is as follows: everyone who can free a paralytic by a word alone can by a word alone forgive sins. Of this reasoning, however, he first sets forth the proof of the major proposition, subjoins the assumption and interposes the conclusion. Of the major proposition he first sets forth the proof in what he says: Which is easier to say: Your sins are forgiven you, or to say: Rise and walk? As if to say: They are of equal ease; therefore he who can do the one can also do the other; and this was the major proposition. Whence the Gloss on that passage of Matthew 9: "Through the remission of punishment, understand the remission of guilt." Now this is understood through that as through something similar and better known. And this is what is said in Jeremiah 32: "No word shall be difficult for you, who show mercy to thousands"; whence Wisdom 11: "But you spare all, O Lord, because you can do all things."
