We have opened to all not the gates of righteousness, but, doors of railing and partisan arrogance; and the first place among us is given, not to one who in the fear of God refrains from even an idle word, but to him who can revile his neighbor most fluently, whether explicitly, or by covert allusion; who rolls beneath his tongue mischief and iniquity, or to speak more accurately, the poison of asps.
We observe each other’s sins, not to bewail them, but to make them subjects of reproach, not to heal them, but to aggravate them, and excuse our own evil deeds by the wounds of our neighbors. Bad and good men are distinguished not according to personal character, but by their disagreement or friendship with ourselves. We praise one day what we revile the next, denunciation at the hands of others is a passport to our admiration; so magnanimous are we in our viciousness, that everything is frankly forgiven to impiety.
Gregory of Nazianzus, In Defence of His Flight To Pontus 79-80
