Jerome
Catena Aurea · Matthäusevangelium 9
And he entered into a ship, and passed over, and came into his own city. 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. And, behold, certain of the Scribes said within themselves, This man blasphemeth. And Jesus knowing their thoughts said, Wherefore think ye evil in your hearts? For whether is easier, to say, Thy sins be forgiven thee; or to say, Arise, and walk? But that ye may know that the Son of man hath power on earth to forgive sins, (then saith he to the sick of the palsy,) Arise, take up thy bed, and go unto thine house. And he arose, and departed to his house. But when the multitude saw it, they marvelled, and glorified God, which had given such power unto men.
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.
