Want to hear a real demon story, one for which I can personally vouch?
A good priest friend of mine — let’s call him Fr. George — is an exorcist. When he performs an exorcism on someone for the first time, Fr. George demands that the demon reveals who his nemesis in heaven is. In other words, he asks him to reveal which saint is his “archenemy.”
The demons never want to reveal this. They never want to reveal any knowledge that might be used against them. But an exorcist will keep hammering away at this, because if he gets a valid answer, it will serve as a weapon and give him a tremendous edge.
In one case of exorcism, Fr. George posed the question to the demon who manifested himself in a certain woman (let’s call her Rachel). But the demon would not answer. But when Fr. George hammered that question over and over again, always commanding in the name of Christ that he reveal the truth, the demon finally — though reluctantly — said, “Thomas.”
Father George asked, “Which Thomas … St. Thomas the Apostle, or St. Thomas Aquinas?” The demon wouldn’t say. So, again, Fr. George hammered that question over and over again, demanding that the demon reveal the answer, “in the name of Christ.”
Finally, the demon said, “Becket, you %*&*@# priest.” In other words, this particular demon’s nemesis was the martyr St. Thomas Becket, otherwise known as St. Thomas of Canterbury, whose feast day is in the Octave of Christmas, on December 29.
Finally, after much praying and adjuration by Fr. George, the demon revealed his name, which he identified as “Murder.”
Later that day, Fr. George called me. It had been a while since we had spoken, and he wanted to catch up. He related the incident that happened with the demon during the exorcism earlier in the day. I replied to him, “Father George, you know that I have a piece of the alb St. Thomas Becket was wearing when he was murdered in his Cathedral. Let me overnight it to you and you can use it with Rachel in your next session.”
I couriered the relic overnight to Fr. George. Halfway through his next session with Rachel, he pulled out the relic and applied it against her body.
The effect was as if all hell broke loose. The demon screamed horribly, as if he was being tortured. In fact, the reaction was so much, that it took Fr. George aback. Under that torture, the demon subsequently revealed that he was the demon who had possessed the king’s men that had murdered Thomas Becket.
Becket’s virtue defeated the demon the first time when he was murdered in the year 1170. Over 800 years later, his relic defeated the same demon a second time.
As you can imagine, the experience was enlightening for all, and was about as surreal as it gets.
St. Thomas Becket, pray for us!
I know that I am going to get asked this question hundreds of times, so I am pre-empting it by answering it right now: The best protection and defence against demons is the Sacrament of Confession and the Eucharist received in a state of sinlessness. Go to Confession and get reconciled with God, else by definition you belong to the enemy. By DEFINITION the sinner belongs to him. Then receive the Eucharist, as Christ in the Most Blessed Sacrament aids you in avoiding sin and in enabling the Holy Spirit to grow in you.
*WARNING: Per Vatican teaching and instruction, NEVER ask demons any questions. Leave that job to trained priests. Priests are protected in this activity by their office. Laypeople are not. Laypeople may command demons to depart (i.e., they may engage in simple deliverance), but they are never to ask them questions or otherwise converse with demons. You have been duly warned.
