St. Leo the Great Since therefore all vices are destroyed by self-restraint, and whatever avarice thirsts for, pride strives for, luxury lusts after, is overcome by the solid force of this virtue, who can fail to understand the aid which is given us by fastings? for therein we are bidden to restrain ourselves, not only in food, but also in all carnal desires. Otherwise it is lost labour to endure hunger and yet not put away wrong wishes; to afflict oneself by curtailing food, and yet not to flee from sinful thoughts. That is a carnal, not 128 a spiritual fast, where the body only is stinted, and those things persisted in, which are more harmful than all delights. What profit is it to the soul to act outwardly as mistress and inwardly to be a captive and a slave, to issue orders to the limbs and to lose the right to her own liberty? That soul for the most part (and deservedly) meets with rebellion in her servant, which does not pay to GOD the service that is due. When the body therefore fasts from food, let the mind fast from vices, and pass judgment upon all earthly cares and desires according to the law of its King III. Thus fasting in mind as well as body, and giving alms freely, we shall win GOD’S highest favour.
