"We will be held accountable for all that we say. The Savior has warned “that every idle word that men shall speak, they shall give account thereof in the day of judgment.” (Matt. 12:36.) This means that no communication shall be without consequence. This includes the slight slips of the tongue, the caustic communications that canker the soul, and the vain, vulgar, and profane words which desecrate the name of Deity."
(L. Lionel Kendrick, “Christlike Communications,” Ensign, Nov 1988, 23)
