It is characteristic of the way that arrogant people teach, that they do not know how to convey their knowledge humbly and cannot express straightforward truths straightforwardly. When they teach, it is clear from their words that they are placing themselves on a pinnacle and looking down on their pupils somewhere in the depths – pupils unworthy to be informed and scarcely even worth the bother of dominating.
The Lord rightly admonished such people through the mouth of the prophet Ezekiel, saying You have ruled your flock cruelly and with violence. For they rule with cruelty and violence when they do not try to correct those under them with rational arguments but try to dominate them and crush them.
St. Gregory the Great, Moral Reflections on Job (ca. 591 A.D.)
