“Language,” Liahona, Oct. 2008, 31
Language
Use language that uplifts, encourages, and compliments others. Use the names of God and Jesus Christ with reverence and respect. Do not use profane, vulgar, or crude language or gestures.
“Conversation is the substance of friendly social activity. It can be happy. It can be light. It can be earnest. It can be funny. But it must not be salty, or uncouth, or foul if one is in sincerity a believer in Christ. …
“[Anyone] who must resort to such language immediately says that he is poverty-ridden in his vocabulary. He does not enjoy sufficient richness of expression to be able to speak effectively without swearing or using foul words. …
“Don’t swear. Don’t profane. Avoid so-called dirty jokes. Stay away from conversation that is sprinkled with foul and filthy words. You will be happier if you do so, and your example will give strength to others.”
President Gordon B. Hinckley (1910–2008), “Take Not the Name of God in Vain,” Ensign, Nov. 1987, 48.
