2 And, behold, they brought to him a man sick of the palsy, lying on a bed: and Jesus seeing their faith said unto the sick of the palsy; Son, be of good cheer; thy sins be forgiven thee.
[AD 367] Hilary of Poitiers on Matthew 9:1-8
Mystically; When driven out of Judæa, He returns into His own city; the city of God is the people of the faithful; into this He entered by a boat, that is, the Church.

In this paralytic the whole Gentile world is offered for healing, he is therefore brought by the ministration of Angels; he is called Son, because he is God's work; the sins of his soul which the Law could not remit are remitted him; for faith only justifies. Lastly, he shows the power of the resurrection, by taking up his bed, teaching that all sickness shall then be no more found in the body.

It is a very fearful thing to be seized by death while the sins are yet unforgiven by Christ; for there is no way to the heavenly house for him whose sins have not been forgiven. But when this fear is removed, honour is rendered to God, who by His word has in this way given power to men, of forgiveness of sins, of resurrection of the body, and of return to Heaven.

[AD 407] John Chrysostom on Matthew 9:1-8
(Hom. xxix.) Christ had above shown His excellent power by teaching, when he taught them as one having authority; in the leper, when He said, I will, be thou clean; by the centurion, who said to Him, Speak the word, and my servant shall be healed; by the sea which He calmed by a word; by the dæmons who confessed Him; now again, in another and greater way, He compels His enemies to confess the equality of His honour with the Father; to this end it proceeds, And Jesus entered into a ship, and passed over, and came into his own city. He entered a boat to cross over, who could have crossed the sea on foot; for He would not be always working miracles, that He might not take away the reality of His incarnation.

By his own city is here meant Capharnaum. For one town, to wit, Bethlehem, had received Him to be born there; another had brought Him up, to wit, Nazareth; and a third received Him to dwell there continually, namely, Capharnaum.

This paralytic is not the same as he in John. For he lay by the pool, this in Capharnaum; he had none to assist him, this was borne on a bed.

He does not universally demand faith of the sick, as, for example, when they are mad, or from any other sore sickness are not in possession of their minds; as it is here, seeing their faith;

Seeing then that they showed so great faith, He also shows His excellent power; with full power forgiving sin, as it follows, He said to the paralytic, Be of good courage, son, thy sins are forgiven thee.

Or, we may suppose even the sick man to have had faith; otherwise he would not have suffered himself to be let down through the roof as the other Evangelist relates.

The Scribes in their desire to spread an ill report of Him, against their will made that which was done be more widely known; Christ using their envy to make known the miracle. For this is of His surpassing wisdom to manifest His deeds through His enemies; whence it follows, Behold, some of the Scribes said among themselves, This man blasphemeth.

He did not indeed contradict their suspicions so far as they had supposed Him to have spoken as God. For had He not been equal to God the Father, it would have behoved Him to say, I am far from this power, that of forgiving sin. But He confirms the contrary of this, by His words and His miracle; Whether is it easier to say, Thy sins are forgiven thee, or to say, Arise, and walk? By how much the soul is better than the body, by so much is it a greater thing to forgive sin than to heal the body. But forasmuch as the one may be seen with the eyes, but the other is not sensibly perceived, He does the lesser miracle which is the more evident, to be a proof of the greater miracle which is imperceptible.

Above, He said to the paralytic, Thy sins are forgiven thee, not, I forgive thee thy sins; but now when the Scribes made resistance, He shows the greatness of His power by saying, The Son of Man hath power on earth to forgive sins. And to show that He was equal to the Father, He said not that the Son of Man needed any to forgive sins, but that He hath power.

This command He added, that it might be seen there was no delusion in the miracle; so it follows to establish the reality of the cure, And he arose, and went away to his own house. But they that stood by yet grovel on the earth, whence it follows, But the multitude seeing it were afraid, and glorified God, who had bestowed such power among men. For had they rightly considered among themselves, they would have acknowledged Him to be the Son of God. Meanwhile it was no little matter to esteem Him as one greater than men, and to have come from God.

[AD 420] Jerome on Matthew 9:1-8
Or; This city may be no other than Nazareth, whence He was called a Nazarene.

On a bed, because he could not walk.

not the sick man's, but theirs that bare him.

O wonderful humility! This man feeble and despised, crippled in every limb, He addresses as son. The Jewish Priests did not deign to touch him. Even therefore His son, because his sins were forgiven him. Hence we may learn that diseases are often the punishment of sin; and therefore perhaps his sins are forgiven him, that when the cause of his disease has been first removed, health may be restored.

We read in prophecy, I am he that blolleth out thy transgressions; (Is. 43:25.) so the Scribes regarding Him as a man, and not understanding the words of God, charged Him with blasphemy. But He seeing their thoughts thus showed Himself to be God, Who alone knoweth the heart; and thus, as it were, said, By the same power and prerogative by which I see your thoughts, I can forgive men their sins. Learn from your own experience what the paralytic has obtained. When Jesus perceived their thoughts, he said, Why think ye evil in your hearts?

Whether or no his sins were forgiven He alone could know who forgave; but whether he could rise and walk, not only himself but they that looked on could judge of; but the power that heals, whether soul or body, is the same. And as there is a great difference between saying and doing, the outward sign is given that the spiritual effect may be proved; But that ye may know that the Son of Man hath power on earth to forgive sins.

Figuratively; the soul sick in the body, its powers palsied, is brought by the perfect doctor to the Lord to be healed. For every one when sick, ought to engage some to pray for his recovery, through whom the halting footsteps of our acts may be reformed by the healing power of the heavenly word. These are mental monitors, who raise the soul of the hearer to higher things, although sick and weak in the outward body.

[AD 420] Jerome on Matthew 9:1-2
(Chapter 9, Verses 1-2) And Jesus got into a boat and crossed over, and came to his own city. And behold, they brought to him a paralytic lying on a bed. And Jesus seeing their faith, said to the paralytic: Take heart, my son, your sins are forgiven. By his city, we understand none other than Nazareth, from where he is also called the Nazarene. And they brought him, as we said before, a paralytic lying on a bed, because he himself was not able to enter. But Jesus, seeing not the faith of the one who was being offered, but of those who were offering, said to the paralyzed man: Have confidence, my son, your sins are forgiven you. Oh, wonderful humility! He calls despised and weak, dissolved in the joints of all his limbs, his son, whom the priests did not consider worthy of touching. Or certainly he calls him son because his sins are forgiven him. According to the allegory, sometimes the soul, lying in its body, with all the powers of its limbs dissolved, is offered to the Lord to be healed by the perfect teacher, and if it is healed by his mercy, it receives such great strength that it immediately carries its bed.

[AD 430] Augustine of Hippo on Matthew 9:1-8
(De Cons. Ev. ii. 25.) That Matthew here speaks of his own city, and Mark calls it Capharnaum, would be more difficult to be reconciled if Matthew had expressed it Nazareth. But as it is, all Galilee might be called Christ's city, because Nazareth was in Galilee; just as all the Roman empire, divided into many states, was still called the Roman city1. Who can doubt then that the Lord in coming to Galilee is rightly said to come into his own city, whatever was the town in which He abode, especially since Capharnaum was exalted into the metropolis of Galilee?

(ubi sup.) And if we adopt this supposition, we must say that Matthew has omitted all that was done from the time that Jesus entered into His own city till He came to Capharnaum, and has proceeded on at once to the healing of the paralytic; as in many other places they pass over things that intervened, and carry on the thread of the narrative, without noticing any interval of time, to something else; so here, And, lo, they bring unto him a paralytic laying on a bed.

[AD 450] Peter Chrysologus on Matthew 9:1-8
(Serm. 50.) The Creator of all things, the Lord of the world, when He had for our sakes straitened Himself in the bonds of our flesh, began to have His own country as a man, began to be a citizen of Judæa, and to have parents, though Himself the parent of all, that affection might attach those whom fear had separated.

(ubi sup.) Of how great power with God must a man's own faith be, when that of others here availed to heal a man both within and without. The paralytic hears his pardon pronounced, in silence uttering no thanks, for he was more anxious for the cure of his body than his soul. Christ therefore with good reason accepts the faith of those that bare him, rather than his own hardness of heart.

(ubi sup.) That that which had been proof of his sickness, should now become proof of his recovered health. And go to thy house, that having been healed by Christian faith, you may not die in the faithlessness of the Jews.

(ubi sup.) Christ has no need of the vessel, but the vessel of Christ; for without heavenly pilotage the bark of the Church cannot pass over the sea of the world to the heavenly harbour.

(ubi sup.) The Lord requires not in this world the will of those who are without understanding, but looks to the faith of others; as the physician does not consult the wishes of the patient, when his malady requires other things.

[AD 604] Gregory the Dialogist on Matthew 9:1-8
(Mor. xxiii. 24.) Or by the bed is denoted the pleasure of the body. He is commanded now he is made whole to bear that on which he had lain when sick, because every man who still takes pleasure in vice is laid as sick in carnal delights; but when made whole he bears this because he now endures the wantonness of that flesh in whose desires he had before reposed.

[AD 856] Rabanus Maurus on Matthew 9:1-8
His rising up is the drawing off the soul from carnal lusts; his taking up his bed is the raising the flesh from earthly desires to spiritual pleasures; his going to his house is his returning to Paradise, or to internal watchfulness of himself against sin.

[AD 1274] Glossa Ordinaria on Matthew 9:1-8
(ap. Anselm.) These words That ye may know, may be either Christ's words, or the Evangelist's words. As though the Evangelist had said, They doubted whether He could remit sins, But that ye may know that the Son of Man hath the power to remit sins, he saith to the paralytic. If they are the words of Christ, the connection will be as follows; You doubt that I have power to remit sins, But that ye may know that the Son of Man hath power to remit sins—the sentence is imperfect, but the action supplies the place of the consequent clause, he saith to the paralytic, Rise, take up thy bed.

[AD 367] Hilary of Poitiers on Matthew 9:2
Now in the narrative of the paralytic a number of people are brought forward for healing. Jesus’ words of healing are worthy of reflection. The paralytic is not told, “Be healed.” He is not told, “Rise and walk.” But he is told, “Take heart, my son; your sins are forgiven you.” The paralytic is a descendent of the original man, Adam. In one person, Christ, all the sins of Adam are forgiven. In this case the person to be healed is brought forward by ministering angels. In this case, too, he is called a son, because he is God’s first work. The sins of his soul are forgiven him, and pardon of the first transgression is granted. We do not believe the paralytic committed any sin [that resulted in his illness], especially since the Lord said elsewhere that blindness from birth had not been contracted from someone’s sin or that of his parents.

[AD 407] John Chrysostom on Matthew 9:2
This paralytic, however, was different from that one who is set forth in John. John 5:1 For he lay at the pool, but this at Capernaum; and that man had his infirmity thirty and eight years, but concerning this, no such thing is mentioned; and the other was in a state destitute of protectors, but this had some to take care of him, who also took him up, and carried him. And to this He says, Son, your sins be forgiven you, but to that He says, Will you be made whole? John 5:6 And the other He healed on a sabbath day, but this not on a sabbath, for else the Jews would have laid this also to His charge; and in the case of this man they were silent, but in that of the other they were instant in persecuting him.

And this I have said, not without purpose, lest any one should think there is a discrepancy from suspecting it to be one and the same paralytic.

But do thou, I pray you, mark the humility and meekness of our Lord. For He had also before this put away the multitudes from Him, and moreover when sent away by them at Gadara, He withstood not, but retired, not however to any great distance.

And again He entered into the ship and passed over, when He might have gone over afoot. For it was His will not to be always doing miracles, that He might not injure the doctrine of His humanity.

Now Matthew indeed says, that they brought him, but the others, that they also broke up the roof, and let him down. And they put the sick man before Christ, saying nothing, but committing the whole to Him. For though in the beginning He Himself went about, and did not require so much faith of them that came unto Him; yet in this case they both approached Him, and had faith required on their part. For, Seeing, it is said, their faith; that is, the faith of them that had let the man down. For He does not on all occasions require faith on the part of the sick only: as for instance, when they are insane, or in any other way, through their disease, are out of their own control. Or rather, in this case the sick man too had part in the faith; for he would not have suffered himself to be let down, unless he had believed.

Forasmuch then as they had evinced so great faith, He also evinces His own power, with all authority absolving his sins, and signifying in all ways that He is equal in honor with Him that begot Him. And mark; He implied it from the beginning, by His teaching, when He taught them as one having authority; by the leper, when He said, I will, be thou clean, Matthew 8:3 by the centurion, when upon his saying, Speak the word only, and my servant shall be healed, He marvelled at him, Matthew 8:8 and celebrated him above all men; by the sea, when He curbed it with a mere word; by the devils, when they acknowledged Him as their judge, and He cast them out with great authority.

Here again in another and a greater way He constrains His very enemies to confess His equality in honor, and by their own mouth He makes it manifest. For He, to signify His indifference to honor (for there stood a great company of spectators shutting up the entrance, wherefore also they let him down from above), did not straightway hasten to heal the visible body, but He takes His occasion from them; and He healed first that which is invisible, the soul, by forgiving his sins; which indeed saved the other, but brought no great glory to Himself. They themselves rather, troubled by their malice, and wishing to assail Him, caused even against their will what was done to be conspicuous. He, in fact, in His abundance of counsel, made use of their envy for the manifestation of the miracle.

Upon their murmuring, then, and saying, This man blasphemes; who can forgive sins but God only? let us see what He says. Did He indeed take away the suspicion? And yet if He were not equal, He should have said, Why fix upon me a notion which is not convenient? I am far from this power. But now has He said none of these things, but quite the contrary He has both affirmed and ratified, as well by His own voice, as by the performance of the miracle. Thus, it appearing that His saying certain things of Himself gave disgust to his hearers, He affirms what He had to say concerning Himself by the others; and what is truly marvellous, not by His friends only, but also by His enemies; for this is the excellency of His wisdom. By His friends on the one hand, when He said, I will, be thou clean, Matthew 8:3 and when He said, I have not found so great faith, no, not in Israel; Matthew 8:10 but by His enemies, now. For because they had said, No man can forgive sins but God only, He subjoined,

But that you may know that the Son of Man has power to forgive sins upon the earth (then says He to the sick of the palsy), Arise, and take up your bed, and go unto your house.

And not here only, but also in another case again, when they were saying, For a good work we stone you not, but for blasphemy, and because that thou, being a man, makest yourself God, John 10:33 neither in that instance did He put down this opinion, but again confirmed it, saying, If I do not the works of my Father, believe me not; but if I do, though ye believe not me, believe the works. John 10:37-38
[AD 420] Jerome on Matthew 9:2
They brought to him, as we said before, a second paralytic lying on a pallet because he was unable to enter. “And Jesus, seeing” not the “faith” of him who was brought forward but of those who were bringing him forward, said to the paralytic, “Take heart, my son, your sins are forgiven you.” O wonderful humility! He addresses as “son” this abject and infirm paralytic with disjointed members whom the priests did not stoop to touch. A son, indeed, because his sins are forgiven him. In line with the biblical metaphor, a soul lying in its body with all the strength of its members gone is brought for healing to the perfect Doctor, the Lord. If the soul is healed through his mercy, it will receive strength enough to immediately take up its pallet.

[AD 450] Peter Chrysologus on Matthew 9:2
Note in this regard, my brothers, that God does not inquire into the wants of those who are deliriously ill. He does not wait to see the faith of the ignorant or probe the senseless wishes of the sick. Yet he does not refuse to help the faith of another, so that by grace alone he confers whatever is proper of the divine will. In fact, my brothers, when does a doctor ever inquire into or examine the wishes of those who are ailing, for a patient is prone to be of a contrary mind in his wishes and demands?

[AD 1022] Symeon the New Theologian on Matthew 9:2
Does He distinguish and separate anyone out, calling one to Himself as foreknown while sending the other away as not predestined? Never! Therefore, “you should not make excuses for your sins” [Psalm 140:4, LXX], nor should you want to make the Apostle’s words an occasion for your own destruction, but should run, all of you, to the Master Who calls you. For even if someone is a publican, or a fornicator, an adulterer, a murderer, or whatever else, the Master does not turn him away, but takes away the burden of his sins immediately and makes him free. And how does He take away the other’s burden? Just as He once took away that of the paralytic when He said to the latter: “My son, your sins are forgiven” (Matthew 9:2), and the man was immediately relieved of his burden and, in addition, received the cure of his body. - "Second Ethical Discourse"
[AD 1107] Theophylact of Ohrid on Matthew 9:2
. "His own city" means Capernaum, for it was there that He was living. He was born in Bethlehem, raised in Nazareth, and lived for an extended length of time in Capernaum. This paralytic is not the same as the one mentioned in John (Jn. 5:2-9), for that one was beside the Sheep’s Pool in Jerusalem, while this one was in Capernaum. And that one had no one to help him, while this one was carried by four men, as Mark says (Mk. 2:3-12), who lowered him through the roof, a fact which fact Matthew omits.
[AD 1107] Theophylact of Ohrid on Matthew 9:2
And He entered into a boat, and passed over, and came into His own city. And, behold, they brought to Him a paralytic, lying on a bed.:
Hs own city means Capernaum, for it was there that He was living. He was born in Bethlehem, raised in Nazareth, and lived for an extended length of time in Capernaum. This paralytic is not the same as the one mentioned in John [5:2-9], for that one was beside the Sheep' Pool in Jerusalem, while this one was in Capernaum. And that one had no one to help him, while this one was carried by four men, as Mark says [Mk. 2:3-12], who lowered him through the roof, a fact which fact Matthew omits.

And Jesus seeing their faith:
Eher the faith of the men who brought the paralytic, for Jesus often worked a miracle on account of the faith of those who brought the one sick; or, of the paralytic himself.

Said to the paralytic, Take courage, child; thy sins be forgiven thee:
Jesus calls him child, either as one of God' creatures, or because he believed. To show that the man's paralysis is a result of his sins, Jesus first forgives him his sins.
