5 Nevertheless, my brethren, the flesh of a good Christian and a believer even in this world for God does thirst: for if the flesh has need of bread, if it has need of water, if it has need of wine, if it has need of money, if this flesh has need of a beast, from God it ought to seek it, not from demons and idols and I know not what powers of this world. For there are certain who when they suffer hunger in this world, leave God and ask Mercury or ask Jove to give unto them, or her whom they call “Heavenly,” or any the like demons: not for God their flesh thirsts. But they that thirst for God, everywhere ought to thirst for Him, both soul and flesh: for to the soul also God gives His bread, that is the Word of Truth: and to the flesh God gives the things which are necessary, for God has made both soul and flesh. For the sake of your flesh you ask of demons: has God made the soul, and the demons made the flesh? He that has made the soul, the Same has made the flesh also: He that has made both of them, the Same feeds both of them. Let either part of us thirst for God, and after labour manifold let either simply be filled.
