Have you noticed that most followers of the Church of Jesus Christ of Latter Day Saints (LDS) commonly called Mormons, don’t drink coffee or tea? You’ll see them enjoying herbal teas (tisanes), hot cider, and many true believers even drink caffeinated soda. The casual observer may jump to the conclusion that this is 1) a law, 2) must have something to do with caffeine. Neither is accurate. This article goes into detail to explain the historical significance, context, and modern interpretation of the prohibition/exhortation against coffee and tea for Mormons.Followers of the LDS church believe in a book of scripture called The Book of Mormon, and the concept of continuous revelation. They believe that the Holy Spirit continues to communicate with humans. Thus, the prophet Joseph Smith received a spontaneous manifestation of God’s insight for living correctly on February 27, 1833. This insight was written down and incorporated into the Doctrines and Covenants of the Church; specifically, these insights are referred to as the Word of Wisdom. It may be an apocryphal story, but it is said that Joseph Smith was moved to ask for God’s insight on the matter of tobacco, and the revelation that resulted included guidance related to the use of tobacco, “warm drinks”,”strong drinks”, wine, meat, herbs and grains. A Word of Wisdom, for the benefit of the council of high priests, assembled in Kirtland, and the church, and also the saints in Zion- To be sent greeting; not by commandment or constraint, but by revelation and the word of wisdom, showing forth the order and will of God in the temporal salvation of all saints in the last days Given for a principle with promise, adapted to the capacity of the weak and the weakest of all saints, who are or can be called saints. Behold, verily, thus saith the Lord unto you: In consequence of evils and designs which do and will exist in the hearts of conspiring men in the last days, I have warned you, and forewarn you, by giving unto you this word of wisdom by revelation- That inasmuch as any man drinketh wine or strong drink among you, behold it is not good, neither meet in the sight of your Father, only in assembling yourselves together to offer up your sacraments before him. And, behold, this should be wine, yea, pure wine of the grape of the vine, of your own make. And, again, strong drinks are not for the belly, but for the washing of your bodies. And again, tobacco is not for the body, neither for the belly, and is not good for man, but is an herb for bruises and all sick cattle, to be used with judgment and skill. And again, hot drinks are not for the body or belly. And again, verily I say unto you, all wholesome herbs God hath ordained for the constitution, nature, and use of man- Every herb in the season thereof, and every fruit in the season thereof; all these to be used with prudence and thanksgiving. The common hot drinks of the time were coffee and tea. But this was a dietary shift for Joseph Smith’s contemporaries, the generation of Mormon Pioneers.
