The Catholic Church, on the contrary, still holds that men, women and cattle may be possessed by devils and prescribes the means of their expulsion. In a work entitled _Rituale ecclesiasticum ad usum clericorum S. Fransisci_ by Pater Franz Xaver Lohbauer (Munich, 1851), there is a chapter on the mode of helping those who are afflicted by demons (_Modus juvandi afflictos a daemone_). The author maintains that nearly all so-called nervous diseases, hysteria, epilepsy, insanity, and milder forms of mental alienation, are either the direct result of diabolical agencies or attended and greatly aggravated by them. A sound mind in a sound body may make a man devil-proof, but Satan is quick to take advantage of his infirmities in order to get possession of his person. The adversary is constantly lying in wait watching for and trying to produce physical derangements as breaches in the wall, through which he may rush in and capture the citadel of the soul. In all cases of this sort the priest is to be called in with the physician, and the medicines are to be blessed and sprinkled with holy water before being administered. Exorcisms and conjurations are not only to be spoken over the patient, but also to be written on slips of consecrated paper and applied, like a plaster, to the parts especially affected. The physician should keep himself supplied with these written exorcisms, to be used when it is impossible for a priest to be present. As with patent medicines, the public is warned against counterfeits, and no exorcism is genuine unless it is stamped with the seal and bears the signature of the bishop of the diocese. According to Father Lohbauer, the demon is the efficient cause of the malady, and there can be no cure until the evil one is cast out. This is the office of the priest; the physician then heals the physical disorder, repairing the damage done to the body, and, as it were, stopping the gaps with his drugs so as to prevent the demon from getting in again. Thus science and religion are reconciled and work together harmoniously for the healing of mankind.
