16. So also in deeds of violence, where there is a desire to harm, whether by contumely or injury; and both of these either by reason of revenge, as one enemy against another; or to obtain some advantage over another, as the highwayman to the traveller; or for the avoiding of some evil, as with him who is in fear of another; or through envy, as the unfortunate man to one who is happy; or as he that is prosperous in anything to him who he fears will become equal to himself, or whose equality he grieves at; or for the mere pleasure in another's pains, as the spectators of gladiators, or the deriders and mockers of others. These be the chief iniquities which spring forth from the lust of the flesh, of the eye, and of power, whether singly, or two together, or all at once. And so do men live in opposition to the three and seven, that psaltery of ten strings, Your ten commandments, O God most high and most sweet. But what foul offenses can there be against You who canst not be defiled? Or what deeds of violence against you who canst not be harmed? But You avenge that which men perpetrate against themselves, seeing also that when they sin against You, they do wickedly against their own souls; and iniquity gives itself the lie, either by corrupting or perverting their nature, which You have made and ordained, or by an immoderate use of things permitted, or in burning in things forbidden to that use which is against nature; Romans 1:24-29 or when convicted, raging with heart and voice against You, kicking against the pricks; Acts 9:5 or when, breaking through the pale of human society, they audaciously rejoice in private combinations or divisions, according as they have been pleased or offended. And these things are done whenever You are forsaken, O Fountain of Life, who art the only and true Creator and Ruler of the universe, and by a self-willed pride any one false thing is selected therefrom and loved. So, then, by a humble piety we return to You; and you purge us from our evil customs, and art merciful unto the sins of those who confess unto You, and hears the groaning of the prisoner, and loosens us from those fetters which we have forged for ourselves, if we lift not up against You the horns of a false liberty—losing all through craving more, by loving more our own private good than You, the good of all.
By St. Augustine
