Now the question arises as to what these legions of devils are doing in the meantime. Some of them are engaged in “going to and fro in the earth and walking up and down in it,” in order to spy out and take advantage of human infirmities. God himself makes use of them to test the fealty of men and their power of holding fast to their integrity under severe temptations, just as the Creator made fossils and concealed them in the different strata of the earth, in order to see whether Christian faith in the truth of revelation would be strong enough to resist the seductions of “science falsely so called.” Other devils enter into living human bodies and give themselves up to evil enchantments as wizards and witches; others still reanimate corpses or assume the form and features of the dead and wander about as ghosts and hobgoblins. Not only were pagans regarded by the Christian Church as devil-worshippers and exorcised before being baptized, but it is also a logical deduction from the doctrine of original sin, that a devil takes possession of every child as soon as it is born and remains there until expelled by an ecclesiastical functionary, who combines the office of priest with that of conjurer and is especially appointed for this purpose. Hence arose the necessity of abrenunciation, as it was called, which preceded baptism in the Catholic Church and which Luther and the Anglican reformers retained. Before the candidate was christened he was exorcised and adjured personally, if an adult, or through a sponsor, if an infant, to “forsake the devil and all his works.” These words, which still hold a place in the ritual, but are now repeated in a perfunctory manner by persons, who have no conception of the magic potency formerly ascribed to them, are a survival of the old formula of exorcism. In the seventeenth century there was a keen competition between the Roman Catholic and the Lutheran clergy in casting out devils, the former claiming that to them alone had been transmitted the exorcising power conferred by Christ upon his apostles. The Protestant churches finally gave up the hocus-pocus and during the eighteenth century it fell into general discredit and disuse among them, although some of the stiffest and most conservative Lutherans never really abandoned it in principle and have recently endeavoured to revive it in practice.
