Profane Swearing
From BiblePortal Wikipedia
Profane Swearing [1]
was severely condemned in the ancient Church, and seems to have been a common practice. Swearing, or foolish or wicked adjurations by any creature or daemon, by the emperor's genius, by angel and by saint, were reprobated. Perjured persons were placed under special penance. Profanity is also punishable by the civil law of Great Britain, and by the laws of some of the states of the United States.
