“One of the most evil dispositions possible is that which satirizes and turns everything to ridicule. God abhors this vice, and has sometimes punished it in a marked manner. Nothing is so opposed to Charity, much more to a devout spirit, as contempt and depreciation of one’s neighbor, and where satire and ridicule exist contempt must be. Therefore contempt is a grievous sin, and our spiritual doctors have well said that ridicule is the greatest sin we can commit in word against our neighbor, inasmuch as when we offend him in any other way, there may still be some respect for him in our heart, but we are sure to despise those whom we ridicule.”
