Matthew 9:5

And whereas, when He spake unto the sick of the palsy, He spake without clearly manifesting His own authority: for He said not, "I forgive thee thy sins," but, "thy sins be forgiven thee:" upon their constraining, He discloses His authority more clearly, saying, "But that ye may know that the Son of Man hath power on earth to forgive sins." Seest thou, how far He was from unwillingness to be thought equal to the Father? For He said not at all, "The Son of Man hath need of another;" or, "He hath given Him authority," but, "He hath authority." Neither doth He say it for love of honor, but "to convince you," so He speaks, "that I do not blaspheme in making myself equal with God." Thus everywhere His will is to offer proofs clear and indisputable; as when He saith, "Go thy way, show thyself to the priest;" and when He points to Peter's wife's mother ministering, and permits the swine to cast themselves down headlong. And in the same manner here also; first, for a certain token of the forgiveness of his sins, He provides the giving tone to his body: and of that again, his carrying his bed; to hinder the fact from being thought a mere fancy. And He doeth not this, before He had asked them a question. "For whether is easier," saith He, "to say, Thy sins be forgiven thee? or to say, Take up thy bed, and go unto thine house?" Now what He saith is like this, "Which seems to you easier, to bind up a disorganized body, or to undo the sins of a soul? It is quite manifest; to bind up a body. For by how much a soul is better than a body, by so much is the doing away sins a greater work than this; but because the one is unseen, the other in sight, I throw in that, which although an inferior thing, is yet more open to sense; that the greater also and the unseen may thereby receive its proof;" thus by His works anticipating even now the revelation of what had been said by John, that "He taketh away the sins of the world." Well then, having raised him up, He sends him to His house; here again signifying His unboastfulness, and that the event was not a mere imagination; for He makes the same persons witnesses of his infirmity, and also of his health. For I indeed had desired, saith He, through thy calamity to heal those also, that seem to be in health, but are diseased in mind; but since they will not, depart thou home, to heal them that are there. Seest thou how He indicates Him to be Creator both of souls and bodies? He heals therefore the palsy in each of the two substances, and makes the invisible evident by that which is in sight. But nevertheless they still creep upon the earth.

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.

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.
