Context

“And in this way are we to understand that "whatsoever shall befall the just man, it shall not make him sad," because his reason is troubled by no misfortune. And thus Christ's sorrow was a propassion, and not a passion. Reply Obj. 3: All sorrow is an evil of punishment; but it is not always an evil of fault, except only when it proceeds from an inordinate affection. Hence Augustine says (De Civ. Dei xiv, 9) : "Whenever these affections follow reason, and are caused when and where needed, who will dare to call them diseases or vicious passions?" Reply Obj. 4: There is no reason why a thing may not of itself be contrary to the will, and yet be willed by reason of the end, to which it is ordained, as bitter medicine is not of itself desired, but only as it is ordained to health.” source
