413 Q. What is Hell? A. Hell is a state to which the wicked are condemned, and in which they are deprived of the sight of God for all eternity, and are in dreadful torments.
“Deprived of the sight of God.” This is called the pain of loss, while the other sufferings the damned endure are called the pain of sense—that is, of the senses. The pain of loss causes the unfortunate souls more torment than all their other sufferings; for as we are created for God alone, the loss of Him—our last end—is the most dreadful evil that can befall us. This the damned realize, and know that their souls will be tortured by a perpetual yearning never to be satisfied. This is aggravated by the thought of how easily they might have been saved, and how foolishly they threw away their happiness and lost all for some miserable pleasure or gratification, so quickly ended.
Besides this remorse, they suffer most frightful torments in all their senses. The worst sufferings you could imagine would not be as bad as the sufferings of the damned really are; for Hell must be the opposite of Heaven, and since we cannot, as St. Paul says, imagine the happiness of Heaven, neither can we imagine the misery of Hell. Sometimes you will find frightful descriptions of Hell in religious books that tell of the horrible sights, awful sounds, disgusting stenches, and excruciating pains the lost souls endure. Now, all these descriptions are given rather to make people think of the torments of Hell than as an accurate account of them. No matter how terrible the description may be, it is never as bad as the reality. We know that the damned are continually tormented in all their senses, but just in what way we do not know.
