26 The dew would more easily resist the morning rays of the sun, than any remains of anger continue in him; but as soon as he had spoken, his indignation departed with his words, leaving behind only his love for what is good, and never outlasting the sun; nor did he cherish anger which destroys even the prudent, or show any bodily trace of vice within, nay, even when roused, he preserved calmness. The result of this was most unusual, not that he was the only one to give rebuke, but the only one to be both loved and admired by those whom he reproved, from the victory which his goodness gained over warmth of feeling; and it was felt to be more serviceable to be punished by a just man than besmeared by a bad one, for in one case the severity becomes pleasant for its utility, in the other the kindliness is suspected because of the evil of the man's character.
But though his soul and character were so simple and divine, his piety nevertheless inspired the insolent with awe: or rather, the cause of their respect was the simplicity which they despised. For it was impossible to him to utter either prayer or curse without the immediate bestowal of permanent blessing or transient pain. The one proceeded from his inmost soul, the other merely rested upon his lips as a paternal reproof. Many indeed of those who had injured him incurred neither lingering requital nor, as the poet says, “vengeance which dogs men's steps;” but at the very moment of their passion they were struck and converted, came forward, knelt before him, and were pardoned, going away gloriously vanquished, and amended both by the chastisement and the forgiveness.
Indeed, a forgiving spirit often has great saving power, checking the wrongdoer by the sense of shame, and bringing him back from fear to love, a far more secure state of mind. In chastisement some were tossed by oxen oppressed by the yoke, which suddenly attacked them, though they had never done anything of the kind before; others were thrown and trampled upon by most obedient and quiet horses; others seized by intolerable fevers, and apparitions of their daring deeds; others being punished in different ways, and learning obedience from the things which they suffered.
