If then such is the grace of fasting, that it makes us into a dwelling place of God, we must welcome it, brethren, gladly, not grieving at the plainness of the diet, for we know that the Lord, though he is able to nourish lavishly, made a banquet for thousands in the wilderness from bread and water. Also because what is unusual, with enthusiasm becomes acceptable and painless. Fasting is not defined by foods alone, but by every abstinence from evil, as our godly fathers have explained. And so, I beg you, let us abstain from despondency, idleness, sluggishness, jealousy, strife, maliciousness, self-indulgence, self-reliance; let us abstain from destructive desire which the many-shaped serpent lays before us when we are fasting.
- Saint Theodore the Studite
