Catena Aurea · Lukasevangelium 16
And it came to pass, that the beggar died, and was carried by the angels into Abraham’s bosom: the rich man also died, and was buried; And in hell he lift up his eyes, being in torments, and seeth Abraham afar off, and Lazarus in his bosom. And he cried and said, Father Abraham, have mercy on me, and send Lazarus, that he may dip the tip of his finger in water, and cool my tongue; for I am tormented in this flame. But Abraham said, Son, remember that thou in thy lifetime receivedst thy good things, and likewise Lazarus evil things: but now he is comforted, and thou art tormented. And beside all this, between us and you there is a great gulf fixed: so that they which would pass from hence to you cannot; neither can they pass to us, that would come from thence. PSEUDO-BASIL. (In Esai. 5.) Hell is a certain common place in the interior of the earth, shaded on all sides and dark, in which there is a kind of opening stretching downward, through which lies the descent of the souls who are condemned to perdition.
(ubi sup.) 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.
