How great punishment must they deserve, who, far from themselves forgiving, do even entreat God for vengeance on their enemies, and as it were diametrically transgress this law; and this while He is doing and contriving all, to hinder our being at variance one with another? For since love is the root of all that is good, He, removing from all sides whatever mars it, brings us together, and cements us to each other.
St John Chrysostom, Homily 19: On St. Matthew: On the Lord’s Prayer
truisms
Do you fast? Give me proof of it by your works. If you see a poor man, take pity on him. If you see a friend being honored, do not envy him. Do not let only your mouth fast, but also the eye, 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 ears by not listening to evil talk and gossip. Let the mouth fast from 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, Homily III:8 On the Statutes
