CHAPTER 16: Catechism on Impurity
That we may understand how horrible and detestable is this sin, which the demons make us commit, but which they do not commit themselves, we must consider what a Christian is. A Christian, created in the image of God, redeemed by the Blood of a God! a Christian, the child of God, the brother of a God, the heir of a God! a Christian, whose body is the temple of the Holy Spirit; that is what sin dishonors. We are created to reign one day in Heaven, and if we have the misfortune to commit this sin, we become the den of the devils. Our Lord said that nothing impure should enter into His kingdom. Indeed, how could a soul that has rolled itself in this filth go to appear before so pure and so holy a God?
We are all like little mirrors, in which God contemplates Himself. How can you expect that God should recognize His likeness in an impure soul? There are some souls so dead, so rotten, that they lie in their defilement without perceiving it, and can no longer clear themselves from it; everything leads them to evil, everything reminds them of evil, even the most holy things; they always have these abominations before their eyes; like the unclean animal that is accustomed to live in filth, that is happy in it, that rolls itself and goes to sleep in it, that grunts in the mud; these persons are an object of horror in the eyes of God and of the holy angels. See, my children, Our Lord was crowned with thorns to expiate our sins of pride; but for this accursed sin, He was scourged and torn to pieces, since He said Himself that after his flagellation all His bones might be counted.
O my children, if there were not some pure souls here and there, to make amends to the good God, and disarm His justice, you would see how we should be punished! For now, this crime is so common in the world, that it is enough to make one tremble. One may say, my children, that Hell vomits forth its abominations upon the earth, as the chimneys of the steam engine vomit forth smoke. The devil does all he can to defile our soul, and yet our soul is everything… our body is only a heap of corruption: go to the cemetery to see what you love, when you love your body. As I have often told you, there is nothing so vile as the impure soul. There was once a saint, who had asked the good God to show him one; and he saw that poor soul like a dead beast that has been dragged through the streets in the hot sun for a week.
By only looking at a person, we know if he is pure. His eyes have an air of candor and modesty which leads you to the good God. Some people, on the contrary, look quite inflamed with passion… Satan places himself in their eyes to make others fall and to lead them to evil. Those who have lost their purity are like a piece of cloth stained with oil; you may wash it and dry it, and the stain always appears again: so it requires a miracle to cleanse the impure soul.
