Behold, verily thus says the Lord unto you: In consequence of evils and designs which will exist in the hearts of conspiring men in the last days, I have warned you and forewarned you, by giving unto you this word of Wisdom by revelation, that inasmuch as any man drinks wine or strong drink among you, behold, it is not good, neither meet in the sight of your Father, only in assembling yourselves in your sacraments before him. And behold, this should be wine of your own make.
T&C 89:2
