Gregory the Great
Catena Aurea · Lukasevangelium 16
Then he said, I pray thee therefore, father, that thou wouldest send him to my father’s house: For I have five brethren; that he may testify unto them, lest they also come into this place of torment. Abraham saith unto him, They have Moses and the prophets; let them hear them. And he said, Nay, father Abraham: but if one went unto them from the dead, they will repent. And he said unto him, If they hear not Moses and the prophets, neither will they be persuaded, though one rose from the dead.
(ut sup.) The hearts of the wicked are sometimes by their own punishment taught the exercise of charity, but in vain; so that they indeed have an especial love to their own, who while attached to their sins did not love themselves. Hence it follows, For I have five brethren, that he may testify to them, lest they also come into this place of torment.
