A certain Bohemian …brought his only son, a secular priest to Rome to be delivered, because he was possessed.
I [an inquisitor] went into a refectory, and that the priest and his father came and sat down at the same table with me. …the father kept sighing and praying Almight God that his journey might prove to have been successful.
I felt great pity for him, and began to ask what was the reason of his journey and of his sorrow.
Then he, in the hearing of his son… answered:"Alas! I have a son possessed by a devil and with great trouble and
                        expense I have brought him here to be delivered."
…I was a little frightened and looked at [the son] closely; and because he took his food with such modesty, and
                        answered pioulsy to all questions, I began to doubt that he was not possessed, but that some infirmity
                        had happened to him.
Then the son himself told what had happened…saying: A certain witch brought this evil upon me. for I was rebuking
                        her on some matter concernined with the discipline of the Church, upbraiding her rather strongly since
                        she was of an obstinate disposition, when she said that after a few days that would happen to me which
                        has happened. And the devil which possess me has told me that a charm was placed by the witchunder
                        a certain tree, and that until it was remeoved I could not be delivered; but he would not tell me which
                        was the tree."
But I would not in the least have believed his words if he had not at once informed me of the facts of the case.
For when I asked about the length of the intervals during which he had the use of his reason more than is usual in the
                        case of persons possessed he answered:" I am only deprived of the use of my reason when i wish to
                        contemplate holy things or to visit sacred places. For the devil specifically told me this in his own words
                        uttered through my mouth that, because he had up to that time been much offended by my sermons to the
                        people, he would in no way allow me to preach."
…according to the father he was a preaacher full of grace and loved by all.
But I, the Inquisitor, wishing for proofs, had him taken for a fortnight and more to various holy places…and in these
                        places he uttered horrible cries while he was being exorcised, now saying that he wished to come forth,
                        and after a little maintaining the contrary.
…as we have said before, in all his behaviour he remained a sobeer priest without any eccentricity, except during the
                        process of any exorcisms; and when these were finished…he showed no sign of madness or any immoderate
                        action.
But when he passed any church, and genuflected in honour of the Glorious Virgin, the devil made him thrust his
                        tongue far out of his mouth; and when he was asked whether he could not restrain himself from doing this,
                        he answered: "I cannot help myself at all, for so he uses all my limbs and organs, my neck, my tongue, and
                        my lungs, whenever he pleases, causing me to speak or to cry out; and i hear the words as if they were
                        spoken by myself, but I am altogether unable to restrain them; and when I try to engage in prayer he
                        attackes me more violently, thrusting out my tongue."…
And there was in the Church of S. Peter a column brought from Solomon's Temple, by virtue of which many who are
                        obsessed with devils are liberated…but even here he could not be delivered, owing to the hidden purpose
                        of God which reserved another method for his liberation.
 

What was the method reserved for his liberation?
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 

Eventually it proved that this domoniac was of that sort of which the Saviour spoke in the Gospel saying: This sort goeth not out save by prayer and fasting. For a venerable Bishop, who had been driven from his see by the Turks, piously took compassion on him, and by fasting on bread and water for forty days, and by prayers and exorcisms, at last through the grace of God delivered him and sent him back to his home rejoicing.
