“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 an 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 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, be 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.
For looking is the food of the eyes, but if this be such as is unlawful or forbidden, it mars the fast; and upsets the whole safety of the soul; but if it be lawful and safe, it adorns fasting.
For it would be among things the most absurd to abstain from lawful food because of the fast, but with the eyes to touch even what is forbidden. Dost thou not eat flesh? Feed not upon lasciviousness by means of the eyes.
Let the ear fast also. The fasting of the ear consists in refusing to receive all evil speakings and calumnies. ‘Thou shalt not receive a false report,’ it says.”
— John Chrysostom
