Recently, the Roman Catholic Church has been training more exorcists. The archbishop of Madrid told The Telegraph, that there has been an "unprecedented rise" in possessions. Today, for example, a Detroit Fox affiliate reported on a home in Gary, Ind. that has been dubbed "a portal to Hell." Latoya Ammons claims she and her three children have been possessed by demons since entering the house. All of them have been exorcised.

As a Vatican expert told the paper, the Vatican wishes to have enough properly trained priests to do away with the popularity of "self-appointed exorcists running around purporting to be acting on behalf of the Church."

We spoke with an exorcist who the Vatican would likely place in that category: the Most Rev. Dr. Isaac Kramer, the interim director of the International Catholic Association of Exorcists. Kramer insists that there are no differences between what ICAE and Roman Catholic Church does during an exorcism, except that many members of the ICAE are not full-time priests—though they are required to at least be Catholic priests. They also, like the Church, interview candidates before performing an exorcism to make sure that their ills cannot be solved medically. In fact, he says that when a Roman Catholic church does not have an exorcist available, his group happily steps in -- although he does agree that there are some unqualified, untrained exorcists performing exorcisms today, which frightens him.

Here is what Kramer has learned through his experiences.

It never gets to the point where someone's head spins and they puke pea soup, like Hollywood likes to show.

I was born Orthodox Jewish. My father's side of the family was Orthodox, and my mother had converted to Judaism for my father. We went to temple. Then after my parents divorced, when I was very young, my mother converted along with my younger brother and I to Pentecostalism. I remember looking at my mom and telling her, when I was nine years old, that I wanted to be a Catholic priest when I grew up. The first thing she said was "the hell if you are."

Eventually I fully converted over to Catholicism. I always wanted to be Catholic. Always. But all through high school and even into my younger twenties, I had gotten deep into Paganism. I was already a high priest with a large Covent, so simply walking away was virtually impossible. So I had to sneak not only from my family, but also from my church. I had a group of over 55 members, which I left to go to Catholic mass.

I have been performing exorcisms since around 2005. I've done three full-human possessions in that time, but average about ten home possessions a month.

My very first possession was with a gentleman a couple of years younger than me. A part of me was terrified, to be completely frank. You train with your mentor, but it's completely different once you're on your own. At that point and time in my life, I still was practicing some pagan beliefs. That was one of the things that the demon brought up against me: How could I do anything with him when I'm also a godless man?

Demons use your fears against you. And they use your dreams and ambitions to manipulate you just the same.

As I continued saying the prayers and commanding this demon to leave him, the gentleman's screams and pains bothered me the most. He had a completely different voice, a deeper voice that was along the lines of a growl. When he was screaming out in pain through the rite of exorcism, he grabbed at the base of his head and his upper abdominal area. That caused me to not want to perform another human exorcism for several years. I ended up passing off that first case. Luckily and thankfully, the next exorcist was able to help the gentleman after several treatments.

One thing that a lot of people misunderstand: They think that there's just one demon. A demon is basically a military leader; they have so many legions of lesser demons that are inside that person with them. You could encounter a demon that might have three legions. That's 64 minor demons. And sometimes you have multiple general demons. So, it's not a one-time fix-all. You're not going to go in, perform an exorcism, and say, "You're now free from all of your demons." It doesn't work that way.

Most true possessions will take months—to years—to successfully remove. The other thing, too, is that the victim still isn't free in the end. If that person, for whatever reason, decides they want to mess with a Ouija board again, or delve into any form of occult, that's dangerous. They're opening themselves right back up, and those demons will come right back inside.

Demons are deceitful. They can make you believe that they're gone, but they're really still there.

For the longest time, here in the U.S., the Roman Catholic Church has only acknowledged two full possessions. I can tell you that there's been more than that. I'm glad that they're willing to state that there's an increase in possessions, because there really has been. But, not everyone that calls in is fully possessed.

If we have a candidate that we strongly believe isn't possessed, we ask them if they've been through a psych evaluation yet or seen a medical doctor. Obviously, that's an instant raise in someone's blood pressure.

We've had people contact us and say, "I've gone to the Baptist church or the Methodist churches and tried to find relief, but I don't know what else to do. Can you help me?" The problem with this is that the victim is just randomly pulling straws. And when they're randomly pulling straws, they're going to go to Google and just find an exorcist in their county. And sadly, the people that they pick—in most cases—are people who are not qualified.

Typically, before an exorcist goes in to perform an exorcism, they must be purified. We actually have to spend days celebrating the mass, going to confessions—spiritually cleansing and purging ourselves of all of our sins. Because a lot of the members of the ICAE are not considered to be full-time priests, we can't live a 24-hour state of prayer, like the Roman Catholic priests and monks should be doing. This is something a lot of novice exorcists don't understand. They'll get a phone call and just say, "I'll be there tonight," and rush right in. And those people who rush in without confessing have no control of their sins, as they haven't given them to God. That's something the demon can use against the priest to overwhelm them, which makes matters worse. The worst-case scenario is the possession of the person who's supposedly there to help.

The demons technically could ignore me, if I didn't go through the purification process.

All exorcists become a bulls-eye.

We don't get paid for our ministry, so we have to work full-time jobs. I do human resources for a private security company.

My last exorcism was just last year, at the end of the summer. It took about four months to help him. Five sessions a week that lasted several hours. It was a gentleman who tried to commit suicide. He shot himself straight in the head, and lived. The possession had been going on for a couple of years, and he eventually got to that point. During the exorcism, the guy tried standing up to come at me, even though he was blind from shooting himself. So I have this six-foot-two man, and I'm only five-ten and about hundred and ninety pounds. I have this linebacker coming at me with this demon in him, charging at me physically.

The rages don't last very long, maybe a few seconds. There are things we can do to subdue the beast, to bring it back down. I used a few different techniques, and the man instantly dropped down to his knees, screaming. Then the assistants were able to restrain him. I can't say what that technique was—there are some secrets we have to keep.

You have some people who want to be an exorcist, but honestly, at the end of the day, they just don't have it the mind for it. They become too shaky. They become too scared. They're just not capable of doing it. It takes a strong-willed person, and someone who is deeply rooted in their faith and not easily spooked.

Last October, I was going to a house case with my team, and the night before we left for a two-hour drive north, I had these dreams that all these different accidents were going to happen on the way there. And so I drove separate from my team. On the way there, I was almost hit once by a semi-truck, and then a car behind me tried cutting me off, which would have taken me out. And the van that the rest of my team was in completely broke down an hour into the trip, leaving them stranded by the side of the road. So the demons do things like this to ensure we can't succeed. And unfortunately, this demon got one last hurrah. I was performing my last rite of exorcism in the living room, and all of a sudden the television turns on. Sitting right beside me is the remote control, and I start chuckling to myself. The homeowner standing next to me started to get paranoid, but I assured her that it was probably a glitch or something with the remote. "But here's the thing," she told me. "The television's not plugged in, and neither is the cable box." I didn't believe her at first, but she showed me where the cords weren't connected to the wall. But she's had no problems since then.
