Gregory the Great — as excerpted in the Catena Aurea on Luke 16:27-31

“(in Hom. 40.) But he who had despised the words of God, supposed that his followers could not hear them. Hence it is added, And he said, Nay, father Abraham, but if one went to them from the dead they would repent. For when he heard the Scriptures he despised them, and thought them fables, and therefore according to what he felt himself, he judged the like of his brethren.”
