"Most of these extraordinary cases come from violating the First Commandment and that means turning to a spirit other than God for comfort, information or power. So, if you're not playing around with other spirits than God, you're not usually going to end up in trouble. Now, if you start getting close to being in trouble, confession and the Mass — for the Catholic who has access to those sacraments — is going to resolve more than 90 percent of the situations," said Adam Blai, author of "The Exorcism Files: True Stories of Demonic Possession" (Sophia Institute Press).


Blai works in the Catholic Diocese of Pittsburgh and is an expert on "religious demonology and exorcism." Learn more at his website, "Religious Demonology."
