The Word of Wisdom was “given for a principle with promise” (D&C 89:3). That word principle in the revelation is a very important one. A principle is an enduring truth, a law, a rule you can adopt to guide you in making decisions. Generally principles are not spelled out in detail. That leaves you free to find your way with an enduring truth, a principle, as your anchor.Members write in asking if this thing or that is against the Word of Wisdom. It’s well known that tea, coffee, liquor, and tobacco are against it. It has not been spelled out in more detail. Rather, we teach the principle together with the promised blessings. There are many habit-forming, addictive things that one can drink or chew or inhale or inject which injure both body and spirit which are not mentioned in the revelation.Everything harmful is not specifically listed; arsenic, for instance—certainly bad, but not habit-forming! He who must be commanded in all things, the Lord said, “is a slothful and not a wise servant” (D&C 58:26).
