A priest in Poland has parents outraged after he had children "screaming and in tears" at a camp he recently ran.

Tomas Wieczorek took it upon himself to use his stature as a priest to perform a mass exorcism on 1,000 attendees at the camp in Gryfice, according to The Mirror.

The camp was advertised as a place for young people to "explore God and devote themselves to spiritual renewal through prayer." However, upon the children's arrival, Wieczorek began exorcising them. The priest allegedley put his hands on the foreheads of children and repeadetly said "Holy Spirit, come. Holy Spirit, come" at one point.

According to eyewitness the Mirror spoke with, at that point children began fainting and crying.

Students who tried to help their peers were told by Wieczorek that "God is entering their souls and banishing the Devil."

One student who was in attendance told the Mirror, "It was really scary, almost like a mental asylum."

The student added that children's reactions to the exorcisms varied.

"Some of them were writhing on the floor, others were laughing hysterically and others were screaming and crying," the child said. "The priest said he was purifying them but it was all too much for most of us."

However, a spokesperson for the camp told the Mirror that they have not received any formal backlash about what went on at the camp. 

"We haven't received any complaints so far, so there's no problem," the spokesperson said.
