Mark 2:11

(ubi sup.) Or else, the sick man is let down after the roof is opened, because, when the Scriptures are laid open to us, we arrive at the knowledge of Christ, that is, we descend to His lowliness, by the dutifulness of faith. But by the sick man being let down with his bed, it is meant that Christ should be known by man, whilst yet in the flesh. But by rising from the bed is meant the soul's rousing itself from carnal desires, in which it was lying in sickness. To take up the bed is to bridle the flesh itself by the bands of continence, and to separate it from earthly pleasures, through the hope of heavenly rewards. But to take up the bed and to go home is to return to paradise. Or else the man, now healed, who had been sick carries back home his bed, when the soul, after receiving remission of sins, returns, even though encompassed with the body, to its internal watch over itself.

Again, He says, Take up thy bed, to prove the greater certainty of the miracle, showing that it is not a mere illusion; and at the same time to show that He not only healed, but gave strength; thus He not only turns away souls from sin, but gives them the power of working out the commandments.

It is necessary to take up also one's bed, that is the body, to the working of good. For then shall we be able to arrive at contemplation, so that our thoughts should say within us, never have we seen in this way before, that is never understood as we have done since we have been cured of the palsy; for he who is cleansed from sin, sees more purely.

(non occ.) Further, He first healed by the remission of sins that which He had come to seek, that is, a soul, so that when they faithlessly doubted, then He might bring forward a work before them, and in this way His word might be confirmed by the work, and a hidden sign be proved by an open one, that is, the health of the soul by the healing of the body.
