Jesus said unto him,
Rise, take up your bed, and walk.

Jesus saith unto him, &c. These words of Christ were practical and efficacious. In saying Arise, He caused him to arise, and healed him. As S. Augustine says, "It was not a command of work, but an operation of healing." And S. Cyril, "Such power and virtue were not of man; it is a property of God alone to command like this." Christ bade him take up his bed, that it might be evident to all that He had healed him, yea, that he had been made instantly stout and strong, so as to be able to carry his bed. Wherefore Euthymius in this passage observes that Christ was accustomed, after the miracles which He wrought, to add something by which their truth and greatness might be perceived. Thus in this instance He bade the paralytic take up his bed, which he could not have done unless he was healed; yea, stout and strong. So after the multiplication of the loaves, He ordered more fragments to be taken up than were originally in the bread. So He said to the leper whom He healed, "Go show thyself to the priest." So He ordered something to be given to eat to the girl whom He raised from the dead (Mark v43).
Tropologically, S. Gregory (Hom12in Ezech.) applies these words to sinners who have been justified by penance, who, by the just judgment of God, suffer temptations from their former sins. He says, "The sick man restored to health is bidden to carry the bed in which he had been carried. For it is necessary that every one who is healed should bear the contumely of the flesh, in which he had before lain in his sickness. What then is it to say, Take up thy bed, and go unto thine house, but, Bear the temptations of the flesh, in which thou hast hitherto lain?"
Thus S. Mary of Egypt for seventeen years after her conversion suffered dreadful temptations of the flesh, because she had previously lived for that number of years immodestly. Sins therefore are their own executioners, and their own righteous avengers. What before pleased afterwards torments: what willingly thou hast done, the same thou shalt hereafter unwillingly suffer.
Symbolically, S. Augustine says (Tract17), "Arise; that Isaiah , love God, who is above. Take up thy bed; i.e, love thy neighbour, bear his infirmities, according to the words, "Bear one another"s burdens, and so fulfil the law of Christ." When thou wast weak thy neighbour carried thee: thou art made whole, carry now thy neighbour. Carry him with whom thou walkest, that thou mayest come to Him with whom thou desirest to abide."
