Every diocese should have an official exorcist. Not all have one though, and that is unfortunate.
Fr. Gabriele Amorth is the senior exorcist of Vatican City. He says that exorcisms are being given less importance and garnering less attention as years go by. Especially as society secularizes and turns to superstition, magic, voodoo, mediums, Satanism, Ouija boards, and things like that to solve paranormal problems.
In his books, *An Exorcist *and An Exorcist: More Stories, he gives many examples for why exorcisms and demonic possessions should be important topics for Catholics.
I recommend those two books. I’ve read them. The accounts of exorcisms that he’s done in the past are really alarming. It’s very good reading. I know that you just can’t go and buy any book that someone recommends, but he is an expert on the subject and one of the first people I turn to for information like exorcisms.
It’s kind of an issue that some modern day Catholics dismiss as being “un-scientific.” They, therefore, turn to medicine and psychology. In most cases, all it is is a medical problem. But after medicine has failed, most people, even Catholics, turn to the wrong people for help (eg witches, shamans, mediums) when they should be turning to exorcists.
