The immediate focus of the Eighth Commandment is falsehood that does injury to one's neighbor. Harm to another person's reputation, therefore, is the special prohibition of this divine mandate.To read Fr. Hardon's writings regarding detraction in its entirety, please go to:
A person's reputation may be injured in various ways, notably by detraction and calumny or slander. Detraction is the unjust violation of the good reputation of another by revealing something true about him. Calumny or slander differs from detraction in that what is said or imputed about a person is not true.
