For as the wicked desire to pass over to the elect, that is, to depart from the pangs of their sufferings, so to the afflicted and tormented would the just pass in their mind by compassion, and wish to set them free. But the souls of the just, although in the goodness of their nature they feel compassion, after being united to the righteousness of their Author, are constrained by such great uprightness as not to be moved with compassion towards the reprobate. Neither then do the unrighteous pass over to the lot of the blessed, because they are bound in everlasting condemnation, nor can the righteous pass to the reprobate, because being now made upright by the righteousness of judgment, they in no way pity them from any compassion.
