With all due respect, Fr. Amorth has done more exorcisms than any priest currently living. He IS the church's expert on the subject. Strange that so many of his observations are true and that there are other authors who concur with him. He's not the only one saying these things. He also says that the new Rite of Exorcism doesn't work. The exorcists weren't consulted when it was written and the result is not effective.
Look through a lectionary some time and find the passages that mention Satan or the devil, either one. Other than the Temptation, there aren'e many. They've been excised with a figurative exacto knife. There also isn't much mention from the pulpits. Seriously. It seems that the church herself has participated in getting people to forget that evil exists.
And for the record, the Inquisition had nothing to do with witchcraft.
And the new Baptismal rite also ignores Satan.
