Father Dave talks with Vatican-certified, practicing exorcist Father Gary Thomas about what’s true and what’s not about exorcisms and demonic possession, and what this means in terms of our faith life. Father Gary is the subject of the new book “The Rite: The Making of a Modern Exorcist,” which chronicles Father Gary’s own Vatican training to become an exorcist, and also gives readers an inside look of the church’s use of the rite of exorcism, and its role in contemporary life.
