After 18 years with the New York Police Department, Sergeant. Ralph Sarchie retired and dedicated himself full time to demonology cases. The upcoming motion Picture Deliver us From Evil is inspired by actual accounts of Sgt. Sarchie's experiences on the field as a demonologist.

Sarchie was a street cop in the 46^th precinct in the Bronx, and says he served in one of the most notoriously dangerous neighborhoods in the early 80s and 90s. His encounters on the streets of New York led him to the study of demonic activity. He calls his handling as a demonologist, "The Work."

"When I'm working as a cop I'm dealing primarily with secondary evil," Sarchie said in a 15 minute testimonial piece uploaded on YouTube, "Evil isn't trying to steal your property it's trying to steal you're very essence, your soul."

In 2001, St. Martin's Press published a book written by Sarchie, entitled Beware the Night, co-written by Lisa Collier Cool. The book described his gruesome experience as a NYPD cop and demonologist. In the book he takes readers into the very hierarchy of a hell on earth to expose demonic rituals.

In the YouTube Testimonial titled "SARCHIE - Deliver Us From Evil" the former police officer says, "I always had a sense of God being real."

Sarchie is a Roman Catholic, and has purposed his life to confront evil.

When he was ten years old his mother explained, in the video, that he became very ill and doctors told the family that there was not anything they could do to save him. He apparently pulled through and his mother said, "God left him here for some reason, to do something."

Sarchie said once he decided to face evil and perform exorcisms, and then demonic activity began to attack his family. He made it clear during the 15 minute video that he understood the price, because demons do not want to be cast out.

"I'm a religious demonologist, I'm not looking to entertain you, I'm here to help you," Sarchie said.

Since making the decision to step out in faith and cast out demons in Jesus name, the former Sergeant said he no longer has the same back up he had in the NYPD, "Years ago I use to have two or three cars filled with investigators," he said, "now I'm just down to two guys."

His investigation partner is a man named Mark Stabinski who Sarchie says helps him when he needs to know "church doctrine" or "canon law."

During the video testimony Sarchie is shown on call helping a family that was dealing with demonic oppression that he calls "a bloodline curse," which is a curse that comes from family members.

While performing exorcisms Sarchie holds a crucifix in his hand and recites a prayer by Pope Leo XIII. He said holding the cross is the equivalent of a gun in the spiritual world. During the video Sarchie is heard commanding the evil spirits "in the name of our Lord Jesus Christ" to leave and "go where the Lord sends you, harming no one along the way."

He then references some knowledge learned from the Bible in Matthew 12:43-44, "This demon will come back with seven more powerful to find the house all tidied up, swept and tidy. That's what exorcism does. It sweeps everything up, it gets all the uncleanliness out. You're now supposed to fill it with the holy and the light. If you don't do that, something more powerful is gonna come back, it's gonna fill that void," Sarchie stated.

He admitted that the learning never stops, "It's always a learning process after the more powerful demons come you have to learn new things," he confessed.

He explains, "these demons they're not looking at me as a physical body, they're looking at me as a soul, and they want that soul, they want to torment that soul."

He also said demons do not discriminate, "It does not matter if you believe or not. You don't have to believe in God. You don't have to believe in the devil. It doesn't withdraw you from this battle. You're involved in it. You were born into this world. No, you probably didn't ask to be born, but you're here. You need to make a choice. You need to pick a side."

Deliver Us From Evil hits theaters July 2. Sarchie had this to say about the film, "If one or two people that see it, really get it and say I believe what this guy is saying, and I believe in his beliefs, in his faith, and what his faith says."
