Leviticus 13:57

Sometimes we know we have done something poorly and avoid including it in our work. But the guilt of it insinuates itself into other acts of ours. For there are some who are subject to carnal uncleanness but reflect on it and return to themselves; they acknowledge the guilt of their depravity. But when they have recovered from their unclean act, they immediately boast of the good of their chastity and swell up with foolish pride. First an unclean act held sway over their bodies; then unclean pride reigns in their minds. What takes hold of them spiritually is like roaming leprosy. It does not wholly leave the garment but changes its place on it. The garment is each of the faithful in the holy church. A roaming and wandering leprosy lays hold of a garment when, by an unreformed fault, guilt takes hold of that soul that seems to be faithful. Let's suppose someone boasts when he possesses riches in this world but then hears from the mouth of a preacher that all these material things are going to perish; he then distributes what he has to the poor. But when he does so, pride swells up in his heart. First he took pride in his possessions; then he took pride in his generosity! This is analogous to the leprosy changing its place on the garment. Another man is given to immoderate and undisciplined expressions of pleasure. Perhaps he is admonished by a preacher. He practices gravity and self-control and tries to restrain himself so that he does not indulge in dissolute pleasure. Often, though, he restrains himself from pleasure, immoderately—more than he should. His soul turns to anger. His sadness gives rise to motives for wrath and disturbs his mind, constricted as it is with the barb of rage. And so the vice of immoderate pleasure passed through immoderate restraint into the vice of anger. It is like a roaming and wandering leprosy which left the place it had and occupied a place it had not had.
