Ambrose of Milan : He also persuades us that this sadness is useful, which is according to God, not according to the world. 'It is necessary,' he says, 'for you to be saddened unto repentance according to God; for according to God, sadness produces salvation, but sadness according to the world produces death. But also consider from the Old Testament that those who were saddened by bodily works found favor, but those who delighted in the works of this world remained in punishment.' Finally, the Hebrews who groaned in the labors of Egypt obtained the grace of the righteous. And because they ate bread in sorrow, they were given spiritual food. — On Paradise 15.76 John Chrysostom : Seest thou wisdom unspeakable? 'For had we not done this,' he says, 'we had done you damage.' And he affirms that indeed which was well achieved to be theirs, but the damage his own, if indeed he had been silent. For if they are likely to be corrected by a sharp rebuke, then, if we did not sharply rebuke, we should have done you damage; and the injury would not be with you alone, but also with us. For just as he that gives not to the merchant what is necessary for his voyage, he it is that causeth the damage; so also we, if we did not offer you that occasion of repentance, should have wrought you damage. Seest thou that the not rebuking those that sin is a damage both to the master and to the disciple? — Homily 15 on 2 Corinthians
