Doctrine and Covenants — Revelation through Joseph Smith…
“ 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 revelation5 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.6 And, behold, this should be wine, yea, pure wine of the grape of the vine, of your own make.7 And, again, strong drinks are not for the belly, but for the washing of your bodies. ”
