With Halloween around the corner and Hollywood releasing horror movies such as “Paranormal Activity” and “Saw VI,” one cannot help but feel chills running down his or her spine. St. John’s Catholic Newman Center had the timing right when it invited exorcist Father Vince Lampert to speak about his experiences Monday night at Foellinger Auditorium. Lampert, the head priest at St. Francis and Clare parish in Greenwood, Ind., was ordained a priest in 1991. He was later asked by the archbishop of Indianapolis if he was willing to train as an exorcist, said Monsignor Gregory Ketcham, director and head chaplain at the Newman Center. “Father Lampert was asked to take on the role of an exorcist because he is very prayerful and faithful, and he has a lot of integrity – he’s a good man,” Ketcham said.
