Exorcists and Exorcisms (Viewer Discretion advised)

Exorcisms can only be performed by a Catholic Priest, not a lay person.  Deliverance can only be performed by those who are trained and have the gift for this ministry.  It can be dangerous for those who are not trained and who may engage in this ministry out of their own personal curiosity or gain.  Adam Blai who features in this video is not an exorcist, but assists Exorcist Priests and also educates Priests on exorcism.
