"But perhaps you will say, What of the fact that, in that common chastisement, like things befall the pious and the impious? It is true, and we confess it; but the chastisement turns to the advantage of the pious, that, being afflicted in the present life, they may come more purified to the future, in which perpetual rest is prepared for them, and that at the same time even the impious may somewhat profit from their chastisement, or else that the just sentence of the future judgment may be passed upon them; since in the same chastisements the righteous give thanks to God, while the unrighteous blaspheme. Therefore, since the opinion of things is divided into two parts, that some things are done by order and others against order, it ought, from those things which are done according to order, to be believed that there is a providence; but with respect to those things which are done against order, we should inquire their causes from those who have learned them by prophetic teaching: for those who have become acquainted with prophetic discourse know when, and for what reason, blight, hail, and pestilence, and such like, have occurred in every generation, and for what sins these have been sent as a punishment; whence causes of sadness, lamentations, and griefs have befallen the human race; whence also trembling sickness has ensued, and that this has been from the beginning the punishment of parricide.
