Gregory of Nazianzus

“Almost every sin is committed for the sake of sensual pleasure; and sensual pleasure is overcome by hardship and distress arising either voluntarily from repentance, or else involuntarily as a result of some salutary and providential reversal. ‘For if we would judge ourselves, we should not be judged; but when we are judged, we are chastened by the Lord, so that we should not be condemned with the world.’ (1 Cor. 11:31-32).”

“But why would anyone on a joyous occasion rake over past unpleasantness and dwell on painful events horrible to experience and repellent to recall? Silence is mightier than words. It clothes the wreckage that befalls us in the deep folds of forgetfulness unless someone stirs up the painful memories for the sole purpose of edifying us by example and, as with illnesses, of helping us avoid the causes that led us to them.”
