For our fast does not consist chiefly of mere abstinence from food, nor are dainties withdrawn from our bodily appetites with profit, unless the mind is recalled from wrong-doing and the tongue restrained from slandering. This is a time of gentleness and long-suffering, of peace and tranquillity: when all the pollutions of vice are to be eradicated and continuance of virtue is to be attained by us. Now let godly minds boldly accustom themselves to forgive faults, to pass over insults, and to forget wrongs. Now let the faithful spirit train himself with the armour of righteousness on the right hand and on the left, that through honour and dishonour, through ill repute and good repute, the conscience may be undisturbed in unwavering uprightness, not puffed up by praise and not wearied out by revilings.
St. Leo I, Sermon 42.2
