Fr. Gabriele Amorth says the devil is in the Vatican

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 added: "When one speaks of 'the smoke of Satan' [a phrase coined by Pope Paul VI in 1972] in the holy rooms, it is all true – including these latest stories of violence and paedophilia."

He claimed that another example of satanic behaviour was the Vatican "cover-up" over the deaths in 1998 of Alois Estermann, the then commander of the Swiss Guard, his wife and Corporal Cedric Tornay, a Swiss Guard, who were all found shot dead. "They covered up everything immediately," he said. "Here one sees the rot".

I found this fascinating:

Father Amorth told La Repubblica that the devil was "pure spirit, invisible. But he manifests himself with blasphemies and afflictions in the person he possesses. He can remain hidden, or speak in different languages, transform himself or appear to be agreeable. At times he makes fun of me."

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. "Anything can come out of their mouths – finger-length pieces of iron, but also rose petals."
