4. Abuse consists in making public the low opinion which one has of another. In evil speaking one makes known a man’s fault behind his back, abuse utters it in his presence. Abuse therefore stands in the same relation to detraction as robbery to theft. While detraction and slander undermine the good opinion others have of a man, abuse aims at depriving him of the outward respect that is shown him. Semei reviled King David; he called him a man of Belial, and threw stones at him (2 Kings xvi. 5). The Jews reviled Our Lord; they called Him a Samaritan, and said He had a devil (John viii. 48).
If two men quarrel, the one who is in the wrong [or is overpowered] usually resorts to abuse. The one who is in the right does not need such weapons; truth conquers of itself. Sneers and sarcasms are a form of this sin. Their object is to make a man ridiculous before others and put him to confusion. By such unkind speeches one may deeply wound one’s neighbor, and fill him with bitter resentment. “The stroke of a whip maketh a blue mark, but the stroke of the tongue will break the bones” (Ecclus. xxviii. 21).
