Bede the Venerable — as excerpted in the Catena Aurea on Mark 2:1-12

“(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.”
