"The mixing of meat and milk is a grave offense, an act that is pervaded altogether with the oppression of life, an oppression of a living being—and of property. Milk, which serves so naturally to feed the tender child, that he might enjoy the mother's breast, was not created so as to stuff with it the stomach, when you are so hard and cruel as to eat meat. The tender child has a prior and more natural right than you."
