Thomas Aquinas,
Summa Theologiae — Question 86 - OF THE CONDITIONS UNDER WHICH THE BODIES OF THE DAMNED WILL RISE AGAIN…
“ I answer that, Since in every movement there must needs be a principle of movement, movement or change may be withdrawn from a movable in two ways: first through absence of a principle of movement, secondly through an obstacle to the principle of movement. Now corruption is a kind of change: and consequently a body which is corruptible on account of the nature of its principles may be rendered incorruptible in two ways. First by the total removal of the principle which leads to corruption, and in this way the bodies of the damned will be incorruptible. ”
