Clement of Alexandria

Let us keep away from us jibing, the originator of insult, from which strifes and contentions and enmities burst forth. Insult, we have said, is the servant of drunkenness. A man is judged, not from his deeds alone, but from his words. "In a banquet," it is said, "reprove not thy neighbour, nor say to him a word of reproach." For if we are enjoined especially to associate with saints, it is a sin to jibe at a saint: "For from the mouth of the foolish," says the Scripture, "is a staff of insult,"—meaning by staff the prop of insult, on which insult leans and rests. Whence I admire the apostle, who, in reference to this, exhorts us not to utter "scurrilous nor unsuitable words." For if the assemblies at festivals take place on account of affection, and the end of a banquet is friendliness towards those who meet, and meat and drink accompany affection, how should not conversation be conducted in a rational manner, and puzzling people with questions be avoided from affection? For if we meet together for the purpose of increasing our good-will to each other, why should we stir up enmity by jibing? It is better to be silent than to contradict, and thereby add sin to ignorance.
