Vatican's chief exorcist Gabriele Amorth poses in Rome; Italy on october 1; 2010. Father Amorth;85;is considered the most expert exorcist in the world; having performed this duty for more than 25 years and 70;000 exorcisms. Vatican's chief exorcist for 25 years; he has just published 'Memoirs of an Exorcist' .He says that sex abuse scandals in the Roman Catholic Church are proof that that 'the Devil is at work inside the Vatican'. He also says 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 and that the attempt on the life of Pope John Paul II in 1981 had been the work of the Devil. He said it sometimes took six or seven of his assistants to to hold down a possessed person. Those possessed often yelled and screamed and spat out nails or pieces of glass; which he kept in a bag. He approves; however; of the 1973 film The Exorcist; which although 'exaggerated' offered a 'substantially exact' picture of possession. PHOTO by Eric Vandeville
