Exorcism is (1) the act of driving out, or warding off, demons, or evil spirits, from persons, places, or things, which are believed to be possessed or infested by them, or are liable to become victims or instruments of their malice; (2) the means employed for this purpose, especially the solemn and authoritative adjuration of the demon, in the name of God, or any of the higher power in which he is subject.
The word, which is not itself biblical, is derived from exorkizo, which is used in the Septuagint (Genesis 24:3 = cause to swear; III(I) Kings 22:16 = adjure), and in Matthew 26:63, by the high priest to Christ, "I adjure thee by the living God. . ." The non-intensive horkizo and the noun exorkistes (exorcist) occur in Acts 19:13, where the latter (in the plural) is applied to certain strolling Jews who professed to be able to cast out demons. Expulsion by adjuration is, therefore, the primary meaning of exorcism, and when, as in Christian usage, this adjuration is in the name of God or of Christ, exorcism is a strictly religious act or rite. But in ethnic religions, and even among the Jews from the time when there is evidence of its being vogue, exorcism as an act of religion is largely replaced by the use of mere magical and superstitious means, to which non-Catholic writers at the present day sometimes quite unfairly assimilate Christian exorcism. Superstition ought not to be confounded with religion, however much their history may be interwoven, nor magic, however white it may be, with a legitimate religious rite.
IN ETHNIC RELIGIONS
The use of protective means against the real, or supposed, molestations of evil spirits naturally follows from the belief in their existence, and is, and has been always, a feature of ethnic religions, savage and civilized. In this connection only two of the religions of antiquity, the Egyptian and Babylonian, call for notice; but it is no easy task, even in the case of these two, to isolate what bears strictly on our subject, from the mass of mere magic in which it is embedded. The Egyptians ascribed certain diseases and various other evils to demons, and believed in the efficacy of magical charms and incantations for banishing or dispelling them. The dead more particularly needed to be well fortified with magic in order to be able to accomplish in safely their perilous journey to the underworld (see Budge, Egyptian Magic, London, 1899). But of exorcism, in the strict sense, there is hardly any trace in the Egyptian records.
In the famous case where a demon was expelled from the daughter of the Prince of Bekhten, human ministry was unavailing, and the god Khonsu himself had to be sent the whole way from Thebes for the purpose. The demon gracefully retired when confronted with the god, and was allowed by the latter to be treated at a grand banquet before departing "to his own place" (op. cit. p. 206 sq.).
Babylonian magic was largely bound up with medicine, certain diseases being attributed to some kind of demoniacal possession, and exorcism being considered easiest, if not the only, way of curing them (Sayce, Hibbert Lect. 1887, 310). For this purpose certain formul
