St. John Chrysostom… I have said these things, not that we may disparage fasting, but that we may honor fasting; for the honor 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.
Dost thou fast? Give me proof of it by thy works!
Is it said by what kind of works?
If thou seest a poor man, take pity on him!
If thou seest in enemy, be reconciled to him!
If thou seest a friend gaining honor, envy him not!
If thou seest 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.
Let the hands fast, by being pure from rapine and avarice.
Let the feet fast, by ceasing from running to the unlawful spectacles.
Let the eyes fast, being taught never to fix themselves rudely upon handsome countenances, or to busy themselves with strange beauties.
