Father Gabriele Amorth, 85, who has been the Vatican's chief exorcist for 25 years and says he has dealt with 70,000 cases of demonic possession, said that the consequences of satanic infiltration included power struggles at the Vatican as well as "cardinals who do not believe in Jesus, and bishops who are linked to the Demon".
He said that hoped every diocese would eventually have a resident exorcist. Under Church Canon Law any priest can perform exorcisms, but in practice they are carried out by a chosen few trained in the rites.
They can start in Los Angeles and banish Mahoney. And then move on to Brown in Orange.
BTW, for those who might read this and think, "How quaint," Satan gets more power from those who would deny his existence than those who would honor him.
