 These sins violate both the commandment against false witness, as well as the command to love one's neighbor as oneself.Not only are gossip and slander held to be covered by the commandment against false witness, Catholic teaching also holds that “every word or attitude is forbidden which by flattery, adulation, or complaisance encourages and confirms another in malicious acts and perverse conduct.Adulation is a grave fault if it makes one an accomplice in another's vices or grave sins.
