A comparison to shew with what violence and what love the souls in Purgatory desire to enjoy God.
If in all the world there were but one loaf of bread to feed the hunger of all creatures, and if they were satisfied by the sight of it alone, then since man, if he be healthy, has an instinct to eat, his hunger, if he neither ate nor sickened nor died, would grow unceasingly for his instinct to eat would not lessen. Knowing that there was only that loaf to satisfy him and that without it he must still be hungry, he would be in unbearable pain. All the more if he went near that loaf and could not see it, would his natural craving for it be strengthened; his instinct would fix his desire wholly on that loaf which held all that could content him; at this point, if he were sure he would never see the loaf again, he would be in Hell. Thus are the souls of the damned from whom any hope of ever seeing their bread, which is God, the true Savior, has been taken away. But the souls in Purgatory have the hope of seeing their bread and wholly satisfying themselves therewith. Therefore they suffer hunger and endure pain in that measure in which they will be able to satisfy themselves with the bread which is Jesus Christ, true God and Savior and our Love.
