Bede the Venerable — as excerpted in the Catena Aurea on Mark 5:1-20

“(ubi sup.) But by the public declaration of the scourge which the madman suffered, the virtue of the Healer appears more gracious. And even the priests of our time, who know how to cast out devils by the grace of exorcism, are wont to say that the sufferers cannot be cured at all, unless they in confession openly declare, as far as they are able to know, what they have suffered from the unclean spirits in sight, in hearing, in taste, in touch, or any other sense of body or soul, whether awake or asleep. It goes on, And he besought him much that he would not send them away out of the country.”
