Slander

The meal with the Apostles at Matthew's to celebrate his conversion. Some of his guests being disreputable, Enemies of Jesus take advantage of it to criticize and Slander him - James Tissot, Brooklyn Museum.

Slander consists of lying about one's Neighbor in order to harm their reputation.

In "The Gospel as it was revealed to me"

• Often someone Slanders to excuse themselves. It is the most common form of lying.
• Blessed are you when you are insulted, persecuted for my sake, and falsely said all kinds of evil against you because of me. - Rejoice and be glad, for your reward is great in heaven: for so they persecuted the prophets, your predecessors."
• Failures in Charity, the degree between mockery and Slander.
• The Sanhedrin develops Slanders and persecutions against Jesus to discredit him in the eyes of the people.-

In foundational Christian texts

In the Catechism of the Catholic Church

• Respect for the reputation of persons forbids any attitude and word likely to cause them unjust harm (cf. Code of Canon Law, can. 220). One who, by words contrary to truth, harms the reputation of others and gives occasion for false judgments concerning them, is guilty of Slander.
• Detraction and Slander destroy the reputation and honor of the Neighbor. Honor is the social testimony given to human dignity, and everyone has a natural right to the honor of their name, their reputation, and respect. Thus, detraction and Slander harm the Virtues of justice and charity.
• "From envy arise hatred, detraction, Slander, joy caused by the misfortune of the Neighbor, and displeasure caused by their prosperity." (Saint Gregory the Great, mor. 31, 45 : PL 76, 621)
