This doctrine, which was the natural consequence of the intellectual condition of the age, acting upon the belief in evil spirits, and upon the scriptural accounts of diabolical intervention, had been still further strengthened by those Platonic theories which, in their Alexandrian form, had so profoundly influenced the early teachings of the Church.16 According to these theories, the immediate objects of the devotions of the pagan world were subsidiary spirits of finite power and imperfect morality—angels, or, as they were then called, demons—who acted the part of mediators; and who, by the permission of the supreme and inaccessible Deity, regulated the religious government of mankind. In this manner, a compromise was effected between monotheism and polytheism. The religion of the state was true and lawful, but it was not irreconcilable with pure theism. The Christians had adopted this conception of subsidiary spirits; but they maintained them to be not the willing agents, but the adversaries, of the Deity; and the word demon, which, among the pagans, signified only a spirit below the level of a Divinity among the Christians signified a devil.
This notion seems to have existed in the very earliest period of Christianity; and, in the second century, we find it elaborated with most minute and detailed care. Tertullian, who wrote in that century, assures us that the world was full of these evil spirits, whose influence might be descried in every portion of the pagan creed. Some of them belonged to that band of rebels who had been precipitated with Satan into the abyss. Others were the angels who, in the antediluvian world, had become attached to the daughters of men; and who, having taught them to dye wool, and to commit the still more fearful offence of painting their faces, had been justly doomed to eternal suffering.17 These were now seeking in every way to thwart the purposes of the Almighty, and their especial delight was to attract to themselves the worship which was due to Him alone. Not only the more immoral deities of heathenism, not only such divinities as Venus, or Mars, or Mercury, or Pluto, but also those who appeared the most pure, were literally and undoubtedly diabolical. Minerva, the personification of wisdom, was a devil, and so was Diana, the type of chastity, and so was Jupiter, the heathen conception of the Most High. The spirits who were worshipped under the names of departed heroes, and who were supposed to have achieved so many acts of splendid and philanthropic heroism, were all devils who had assumed the names of the dead. The same condemnation was passed upon those bright creations of a poetic fancy, the progenitors of the mediæval fairies, the nymphs and dryads who peopled every grove and hallowed every stream.18 The air was filled with unholy legions,19 and the traditions of every land were replete with their exploits. The immortal lamp, which burnt with an unfading splendour in the temple of Venus; the household gods that were transported by invisible hands through the air; the miracles which clustered so thickly around the vestal virgins, the oracular shrines, and the centres of Roman power, were all attestations of their presence. Under the names of Sylvans and Fauns, and Dusii, they had not only frequently appeared among mankind, but had made innumerable women the objects of their passion. This fact was so amply attested, that it would be impudence to deny it.20 Persons possessed with devils were constantly liberated by the Christians, and tombs of the exorcists have been discovered in the catacombs,21 If a Christian in any respect deviated from the path of duty, a visible manifestation of the devil sometimes appeared to terrify him. A Christian lady, in a fit of thoughtless dissipation, went to the theatre, and at the theatre she became possessed with a devil. The exorcist remonstrated with the evil spirit on the presumption of its act. The devil replied apologetically, that it had found the woman in its house.22 The rites of paganism had in some degree pervaded all departments of life, and all were therefore tainted with diabolical influence. In the theatre, in the circus, in the market-place, in all the public festivals, there was something which manifested their presence. A Christian soldier, on one occasion, refused even to wear a festal crown, because laurels had been originally dedicated to Bacchus and Venus; and endured severe punishment rather than comply with the custom. Much discussion was elicited by the transaction, but Tertullian wrote a treatise23 maintaining that the martyr had only complied with his strict duty.
The terror which such a doctrine must have spread among the early Christians may be easily conceived. They seemed to breathe an atmosphere of miracles. Wherever they turned, they were surrounded and beleaguered by malicious spirits, who were perpetually manifesting their presence by supernatural acts. Watchful fiends stood beside every altar; they mingled with every avocation of life, and the Christians were the special objects of their hatred. All this was universally believed; and it was realised with an intensity which, in this secular age, we can scarcely conceive. It was realised as men realise religious doctrines, when they have devoted to them the undivided energies of their lives, and when their faith has been intensified in the furnace of persecution.
The bearing of this view upon the conception of magic is very obvious. Among the more civilised pagans, as we have seen, magic was mainly a civil, and in the last days of the empire, mainly a political crime. In periods of great political insecurity, it assumed considerable importance; at other periods it fell completely into the background. Its relation to the prevailing religion was exceedingly indeterminate, and it comprised many rites that were not regarded as in any degree immoral. In the early Church, on the other hand, it was esteemed the most horrible form of sacrilege, effected by the direct agency of evil spirits. It included the whole system of paganism, explained all its prodigies, and gave a fearful significance to all its legends. It assumed, in consequence, an extraordinary importance in the patristic teaching, and acted strongly and continually on the imaginations of the people.
When the Church obtained the direction of the civil power, she soon modified or abandoned the tolerant maxims she had formerly inculcated; and, in the course of a few years, restrictive laws were enacted, both against the Jews and against the heretics. It appears, however, that the mutitude of pagans, in the time of Constantine, was still so great, and the zeal of the emperor so languid, that he at first shrank from directing his laws openly and avowedly against the old faith, and an ingenious expedient was devised for sapping it at its base, under the semblance of the ancient legislation. Magic, as I have said, among the Romans, included not only those appeals to evil spirits, and those modes of inflicting evil on others, which had always been denounced as sacrilegious, but also certain methods of foretelling the future, which were not regarded as morally wrong, but only as politically dangerous. This latter department formed an offshoot of the established religion, and had never been separated from it with precision. The laws had been devised for the purpose of preventing rebellions or imposition, and they had been executed in that spirit. The Christian emperors revived these laws, and enforced them with extreme severity, but directed them against the religion of the pagans.24 At first, that secret magic which the decemvirs had prohibited, but which had afterwards
