Vatican City, Apr 10, 2015 / 04:02 am (CNA/EWTN News).- This month the Vatican will gather a wide range experts in the field of exorcism with the aim of shedding light on demonic possession from both theological and scientific perspectives.

The annual course, “Exorcism and Prayer of Liberation,” is designed for priests and lay persons interested in learning how to recognize a case of demonic possession when they see one – and what to do about it.
