“Profaned Not Neither Blaspheme”

Church Educational System

President Gordon B. Hinckley (1910–2008) affirmed the need to keep our words pure:

“I say this to the boys. I say it also to any of you older men who have a similar problem. I do so with love. I know that the Lord is pleased when we use clean and virtuous language, for He has set an example for us. His revelations are couched in words that are affirmative, that are uplifting, that encourage us to do what is right and to go forward in truth and goodness.
“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” (in Conference Report, Oct. 1987, 59; or Ensign, Nov. 1987, 48).
