 Not in this day and age. So you can only exorcise those who are less than perfectly possessed. There is no exorcism for the perfectly possessed. None. None whatever. The perfectly possessed, you can give them a bottle of holy water and they'll drink it. They can handle a host, a consecrated host at mass. It means nothing to them. They can look on a crucifix and say, oh, well, that's Romanesque, and it probably is 9th century. You know?
