It's from a few weeks ago, so... not an April Fool?!
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."
