Encyclopedia of Mormonism, p. 1584 “Word of Wisdom is the common title for a revelation that counsels Latter-day Saints on maintaining good health and is published as Doctrine and Covenants: section 89. The practice of abstaining from all forms of alcohol, tobacco, coffee, and tea, which may outwardly distinguish active Latter-day Saints more than any other practice, derives from this revelation.”
Mark 7:15 “There is nothing from without a man, that entering into him can defile him: but the things which come out of him, those are they that defile the man.”
