A New York woman who levitated six inches off the ground, mysteriously spoke in foreign languages and demonstrated paranormal powers made medical history in 2008 because a panel of doctors from New York Medical College agreed she was possessed by the devil.

In presenting the case of “Julia” in the New Oxford Review, board-certified psychiatrist Dr. Richard Gallagher cautioned that religious practitioners should be on alert for what he called a “rapidly growing worldwide phenomenon.”

Gallagher’s warning was on point, say exorcists, who claim there are now so many devils out there, the Vatican can’t recruit enough exorcists to chase them away.

The Rev. Vincent Lampert, the head priest at St. Malachy’s in Indianapolis, Indiana, reports he was one of about 400 Catholic leaders who met in Rome in October to strategize on how to recruit and train more exorcists, who use holy water and prayer to combat evil.

The situation is dire, he said, because rampant pornography, illegal narcotic use and the occult have made it easier for Satan to cast his net.

“Exorcism is like triage. We’re the emergency crew — but there aren’t enough of us,” Lampert told The Post.

Lampert — who says he recently chased a demon out of a parishioner who was cursed by his girlfriend’s mother — said he was one of about a dozen priests representing the US at the International Association of Exorcists conference, a Vatican-sanctioned retreat.

‘Many drug traffickers practice forms of the occult. They incorporate voodoo or black magic that gives them the power to succeed.’

“We’re in a fight with drugs, the occult, pornography,” he explained. “This is an entry point for evil and we need to take these souls back.”

Valter Cascioli, the psychologist and scientific consultant for the exorcists’ association, agreed demons across the world have multiplied and there aren’t enough priests to fight them.

“The lack of exorcists is a real emergency,” Cascioli told the Italian newspaper La Stampa.

An article in Catholic Online published in October declared: “WORLD UNDER ATTACK — Army of demons has led to spike in exorcism.”

The article explained that Catholics believe demons jump into a body through various vices or a spell.

“A demon’s purpose is to drag your soul to hell upon death. By disturbing your body and behavior, they turn you from God, keep you away from church, and will encourage you to harm yourself. They encourage suicide,” it read.

The Rev. Vincenzo Taraborelli is a 79-year-old priest who says he is too afraid to retire.

“I told the bishop that I can’t find anyone willing to do this. Many of them are scared. Even priests can be scared. It’s a difficult life,” the Italian priest, who says he treats up to 30 people a day in the back of his church in Rome, told the BBC.

Meanwhile, another exorcist on the ground in New York City told The Post he believes there is an increase in demonic activity throughout the five boroughs because of the voodoo that drug dealers and other criminals practice.

‘Exorcism is like triage. We’re the emergency crew — but there aren’t enough of us.’

Marcos Quinones, a New York state chaplain who claims he works as an occult investigator, says the new generation of drug dealers spray their illicit products with incantations and evil spells before putting it on the street.

“Many drug traffickers practice forms of the occult. They incorporate voodoo or black magic that gives them the power to succeed. It makes the product more powerful and creates a stronger addict. In essence, they’re doubling the curse the drugs cause anyway,” he said.

Quinones pointed to a strain of synthetic marijuana that hit New York this summer known as K-2 that turned users into walking zombies who passed out cold along sidewalks in Brooklyn and vomited through the streets.

“With the zombie drugs, you can see how dangerous this is getting,” he said. “The original word ‘pharmacy’ is derived from the Greek ‘pharma,’ which literally means sorcery.”

He said some dealers practice Santa Muerte as they prepare drugs for delivery. Santa Muerte is a Mexican folk saint of death and is depicted as an intimidating skeletal figure holding a scythe.

“They say incantations over their product as they pray to La Santa Muerte,” he claimed. “I’ve seen cases where the drug dealer initiates all the members into whatever he’s practicing and teach them how to bless this very dangerous poison before putting it on the street.”

Quinones said there is a difference between mental illness such as schizophrenia — known medically to be exacerbated by drug use — and demonic possession.

“If demons exist and you take a drug that changes your thinking pattern, that opens itself up to the entities of these demons. Demons cause many things, but it’s a spiritual problem. How do we help them?”

Tainted drugs aside, Quinones said he tries to warn young people against keeping talismans or other objects involving a spiritual entity.

“I lecture in church about the dangers of the occult, especially with teenagers. Oftentimes a teenager will tell me he’s having problems and when I ask about it, it turns out he’s bought an object while traveling to Puerto Rico or the Dominican Republic and I say, ‘You have to get rid of it.’”

Quinones said occult members perform animal sacrifices in the woods of Long Island. “I saw one a couple of months ago. It was a Santeria ritual that was left with red candles and candy. They had sacrificed a couple of chickens.”

Joe Zwilling, spokesman for the New York Archdiocese, confirmed city priests are conducting exorcisms — but refused to go into specifics.

“Due to the sensitive nature of their work, they do not do interviews,” he said. “And we do not release their names publicly.”

Lampert, however, urges all archdioceses to speak publicly about exorcism.

“Some people don’t want the attention, but I always felt those in need don’t know who to turn to if we’re not vocal about it,” he said.

Lampert is so adamant about fighting the devil, he tweets about it under the handle FrVinceLampert.

Meeting with other exorcists, sharing success stories and spreading the word is crucial, he said.

“We’re looking at resources that people can turn to. Mothers, youth pastors, youth ministers, how to train them,” he said.

Lampert cautioned that while prayers initially may keep demons at bay, long-term treatment is needed.

“In praying with them, we give them a sense of hope and knowing that they’re not alone — but they have to do the work, too.

“It’s about reintegrating people into a life of faith. If they don’t want skin in the game, they don’t want to pray or follow up, then we can’t help them.”
