Therefore, dearly-beloved, seeing that, as we are taught by our Redeemer's precept, "man lives not in bread alone, but in every word of God," and it is right that Christian people, whatever the amount of their abstinence, should rather desire to satisfy themselves with the "Word of God" than with bodily food, let us with ready devotion and eager faith enter upon the celebration of the solemn fast, not with barren abstinence from food, which is often imposed on us by weakliness of body, or the disease of avarice, but in bountiful benevolence: that in truth we may be of those of whom the very Truth speaks, "blessed are they which hunger and thirst after righteousness, for they shall be filled." Let works of piety, therefore, be our delight, and let us be filled with those kinds of food which feed us for eternity. Let us rejoice in the replenishment of the poor, whom our bounty has satisfied. Let us delight in the clothing of those whose nakedness we have covered with needful raiment. Let our humaneness be felt by the sick in their illnesses, by the weakly in their infirmities, by the exiles in their hardships, by the orphans in their destitution, and by solitary widows in their sadness: in the helping of whom there is no one that cannot carry out some amount of benevolence. For no one's income is small, whose heart is big: and the measure of one's mercy and goodness does not depend on the size of one's means.
Leo the Great, Sermon 40 (Sermon II on Lent)
