"If there's something strange in your neighborhood, who you gonna call?"
If there’s something weird, and it don’t look good, whatever you do, don’t call the Ghostbusters. In most cases of possible demonic activity, whether in a haunted house or a possessed person, only an authorized priest can expel the presence of evil.
Ghostbusters won’t be able to do anything and may make things worse. The devil thrives on tricking humans and the presence of paranormal investigators will only give him a larger audience for his show.
If you truly want to investigate strange and unsettling activity, only an exorcist can help. They have been trained how to approach each situation in prayer and can identify whether or not the demonic is involved.
However, exorcists are not listed on Yelp and do not have their information readily available to the public. If you search Google for “how to contact an exorcist,” countless sites appear, many of them claiming to have exorcists on staff. Some state that they are adherents of the Old Roman Catholic Church, and even have “bishops” and “priests” who work for them. Do not contact them. Whoever they are, they are not acting with the authority of the Catholic Church.
The first step in contacting an exorcist istalking with your local parish priest (or spiritual director if you have one). Your pastor was assigned by the local bishop to be the shepherd of your soul and has a certain authority in the spiritual realm. He can guide you, ask questions, and advise you on the next step.
If you think your pastor is not listening to your concerns, consult other priests in the area whom you trust. It is extremely important to talk with someone from the Church about the issue, as it is always important to receive feedback from a third party.
