Maternal temperance and avoidance of alcohol protect the physical, mental, and moral health of the child.

Original passage

But if the mother unswervingly adheres to right principles, if she is temperate and self-denying, if she is kind, gentle, and unselfish, she may give her child these same precious traits of character. Very explicit was the command prohibiting the use of wine by the mother. Every drop of strong drink taken by her to gratify appetite endangers the physical, mental, and moral health of her child, and is a direct sin against her Creator.
