After they have reduced their physical strength by a reduced quantity and a poor quality of food, some conclude that their former way of living is the best. The system must be nourished. Yet we do not hesitate to say that flesh meat is not necessary for health or strength. If used it is because a depraved appetite craves it. Its use excites the animal propensities to increased activity and strengthens the animal passions. When the animal propensities are increased, the intellectual and moral powers are decreased. The use of the flesh of animals tends to cause a grossness of body and benumbs the fine sensibilities of the mind. 1TT 195.1
Will the people who are preparing to become holy, pure, and refined, that they may be introduced into the society of heavenly angels, continue to take the life of God's creatures and subsist on their flesh and enjoy it as a luxury? From what the Lord has shown me, this order of things will be changed, and God's peculiar people will exercise temperance in all things. Those who subsist largely upon flesh cannot avoid eating the meat of animals which are to a greater or less degree diseased. The process of fitting animals for market produces in them disease; and fitted in as healthful manner as they can be, they become heated and diseased by driving before they reach the market. The fluids and flesh of these diseased animals are received directly into the blood, and pass into the circulation of the human body, becoming fluids and flesh of the same. Thus humors are introduced into the system. And if the person already has impure blood, it is greatly aggravated by the eating of the flesh of these animals. The liability to take disease is increased tenfold by meat eating. The intellectual, the moral, and the physical powers are depreciated by the habitual use of flesh meats. Meat eating deranges the system, beclouds the intellect, and blunts the moral sensibilities. We say to you, dear brother and sister, your safest course is to let meat alone. 1TT 195.2
