I'm looking the actual source reference for the modern application of the Word of Wisdom. i.e. No Tobacco, Coffee, Tea, Alcohol. D&C 89 only specifically prohibits Tobacco, Hot Drinks, and "Strong Drink" (While making allowance for "Mild Drink"). I can find many many references in conference talks discussing prohibition of Coffee, Tea, Alcohol. The GAs in these cases usually just refer to "Modern Day Revelation" but they fail to ever cite the primary source. Sometimes they also incorrectly imply that D&C 89 covers these issues specifically. The primary source is the one I'm looking for help locating. Which prophet received this revelation and when? I'd really like to read it and be able to cite it as a source reference. Thank you.
