Thou hast written regarding the four canine teeth in man, saying that these teeth, two in the upper jaw and two in the lower, are for the purpose of eating meat. Know thou that these four teeth are not created for meat-eating, although one can eat meat with them. All the teeth of man are made for eating fruit, cereals and vegetables. These four teeth, however, are designed for breaking hard shells, such as those of almonds. But eating meat is not forbidden or unlawful, nay, the point is this, that it is possible for man to live without eating meat and still be strong. Meat is nourishing and containeth the elements of herbs, seeds and fruits; therefore sometimes it is essential for the sick and for the rehabilitation of health. There is no objection in the Law of God to the eating of meat if it is required. So if thy constitution is rather weak and thou findest meat useful, thou mayest eat it.
