Augustine of Hippo

It happens regularly and it happens often that a man is cast down for a short time while he is being reproved, that he resists and fights back. But afterwards he reflects in solitude where there is no one but God and himself, and where he does not fear the displeasure of others by being corrected, but does fear the displeasure of God by refusing correction. Thereafter, he does not repeat the act which was justly censured but now loves the brother, whom he sees as the enemy of his sin, as much as he hates the sin itself.

Letter 210 ↗

Bede

Rebuke a wise man, and he will love you. He speaks of a wise man who is in progress, that is, a lover of wisdom, whom he previously called a little one due to humility. For a perfect wise man does not need to be rebuked.

Commentary on Proverbs ↗

Bonaventure

"Do not rebuke a scoffer, lest he hate you: rebuke a wise man, and he will love you." It is better to be corrected by a wise man than to be deceived by the flattery of fools. A fool, when he is corrected, does not withdraw from evil nor is he led to good. He who recognizes his faults, and they displease him, is wise. He who rebukes a person and calls him back from evil renders him a greater service than if he gave him the whole world.
