St. John . Do not let only your mouth 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 free of avarice. Let the feet fast, by ceasing to run after sin. Let the eyes fast, by disciplining them not to glare at that which is sinful… Let the ear fast… by not listening to evil talk and gossip… Let the mouth fast from the foul words and unjust criticism. For what good is it if we abstain from birds and fishes, but bite and devour our brothers?” (St. John Chrysostom – “The Proof of Fasting”)
