WASHINGTON, DC (Inside Catholic) - they know it."
Father Euteneuer does not speak as a theorist. Since 2003 he’s had extensive experience ministering to those possessed by demons. His introduction to the demonic world happened when a family asked him for help for one of their members, and he eventually asked for permission to perform the rite of exorcism. He has been doing them ever since.
…, as Father Euteneuer made clear, this entire dark spiritual world “cannot operate without permission from human beings.” He pointed out that the widely-seen film, The Exorcism of Emily Rose, based upon the actual case of Anneliese Michel, makes it seem like a possession can occur against a person’s will.
Demons play by the rules, as it were. They can only enter a person when invited, and they will leave when subjected through the rite of exorcism to the authority of the Church. “All demons understand is authority,” according to Father Euteneuer. He told me of a time he was with someone who was possessed – not intending to do an exorcism because permission had not yet been given – and the demon spoke to him saying, “The Church is not here.”
Father Euteneuer reminded me that as fallen angels, demons are smarter than any human being. “The darkest demon is smarter than I am,” he said. An exorcist must remain aware of the demon’s ability to know everything about the person they are possessing, including family members, and those who may enter the room to cast them out.
