Matthew 9:4

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.

Upon their murmuring, then, and saying, "This man blasphemeth; who can forgive sins but God only?" let us see what He saith. 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 hath He said none of these things, but quite the contrary He hath 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," and when He said, "I have not found so great faith, no, not in Israel;" but by His enemies, now. For because they had said, "No man can forgive sins but God only," He subjoined, "But that ye may know that the Son of Man hath power to forgive sins upon the earth (then saith He to the sick of the palsy), Arise, and take up thy bed, and go unto thine house." In this case indeed He discloses also another sign, and that no small one, of His own Godhead, and of His equality in honor with the Father. For whereas they said, "To unbind sins pertains to God only," He not only unbinds sins, but also before this He makes another kind of display in a thing which pertained to God only; the publishing the secrets in the heart. For neither had they uttered what they were thinking. For "behold, certain of the scribes," it saith, "said within themselves. This man blasphemeth. And Jesus knowing their thoughts, said, Wherefore think ye evil in your hearts?" But that it belongs to God only to know men's secrets, hear what saith the prophet, "Thou most entirely alone knowest the hearts;" and again, "God trieth the hearts and reins;" and Jeremiah too saith, "The heart is deep above all things, and it is man, and who shall know him?" and, "Man shall look on the face, but God on the heart." And by many things one may see, that to know what is in the mind belongs to God alone. Implying therefore that He is God, equal to Him that begat Him; what things they were reasoning in themselves (for through fear of the multitude, they durst not utter their mind), this their opinion He unveils and makes manifest, evincing herein also His great gentleness. "For wherefore," saith He, "think ye evil in your hearts?" And yet if there were cause for displeasure, it was the sick man who should have been displeased, as being altogether deceived, and should have said "One thing I came to have healed, and amendest Thou another? Why, whence is it manifest that my sins are forgiven?" But now he for his part utters no such word, but gives himself up to the power of the healer; but these being curious and envious, plot against the good deeds of others. Wherefore He rebukes them indeed, but with all gentleness. "Why, if ye disbelieve," saith He, "what went before, and account my saying a boast; behold I add to it also another, the uncovering of your secrets; and after that again another." What then is this? The giving tone to the body of the paralyzed.

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?
