For the value of fasting consists not in abstinence from food, but in withdrawing from sinful practices; since he who limits his fasting only to an abstinence from meats, is one who especially disparages it. Do you fast? Give me proof of it by your works! Is it said by what kind of works? If you see a poor man, take pity on him! If you see in enemy, be reconciled to him! If you see a friend gaining honour, envy him not! If you see a handsome woman, pass her by! For let not the mouth only fast, but also the eye, and the ear, and the feet, and the hands, and all the members of our bodies.
- St. John Chrysostom
