The only 'official' document I know of regarding caffeine is a Priesthood Bulletin (the kind usually read by the Bishopric member over the pulpit) that states:
"With reference to cola drinks, the Church has never officially taken a position on the matter, but the leaders of the Church have advised, and we do now specifically advise, against the use of any drink containing harmful habit-forming drugs under circumstances that would result in acquiring the habit. Any beverage that contains ingredients harmful to the body should be avoided."
Priesthood Bulletin, 1972
Later, Elder Vaughn J. Featherstone shared the following story in General Conference:
I was over in England a while back and a bishop asked me, "What is the Church's stand on cola drinks?" I said, "Well, I can't remember the exact wording of the bulletin, but I remember seeing the bulletin when I was a stake president. The Church, of course, advises against them."
He said, "Well, I have read the Priesthood Bulletin, but that isn't what it says to me."
And I said, "Would you get your Priesthood Bulletin? Let's read it together." And so we found under the heading "Cola Drinks": "⦠the leaders of the Church have advised, and we do now specifically advise, against use of any drink containing harmful habit-forming drugs. â¦" (The Priesthood Bulletin, Feb. 1972, p. 4.)
He said, "Well, you see, that doesn't mean cola."
I said, "Well, I guess you will have to come to your own grips with that, but to me, there is no question." You see, there can't be the slightest particle of rebellion, and in him there is. We can find loopholes in a lot of things if we want to bend the rules of the Church."
Vaughn J. Featherstone, âA Self-Inflicted Purging,â Ensign, May 1975, 66
I personally use them for medicinal purposes only, like when returning to Idaho following a late afternoon or evening football game. ;-) So I guess I'm still finding loopholes too.
Go Cougs!!!
