On Threefold Wisdom
3 We must, indeed, endeavour to ascertain whether that wisdom of the princes of this world, with which they endeavour to imbue men, is introduced into their minds by the opposing powers, with the purpose of ensnaring and injuring them, or only for the purpose of deceiving them, i.e., not with the object of doing any hurt to man; but, as these princes of this world esteem such opinions to be true, they desire to impart to others what they themselves believe to be the truth: and this is the view which I am inclined to adopt. For as, to take an illustration, certain Greek authors, or the leaders of some heretical sect, after having imbibed an error in doctrine instead of the truth, and having come to the conclusion in their own minds that such is the truth, proceed, in the next place, to endeavour to persuade others of the correctness of their opinions; so, in like manner, are we to suppose is the procedure of the princes of this world, in which to certain spiritual powers has been assigned the rule over certain nations, and who are termed on that account the princes of this world. There are besides, in addition to these princes, certain special energies of this world, i.e., spiritual powers, which bring about certain effects, which they have themselves, in virtue of their freedom of will, chosen to produce, and to these belong those princes who practise the wisdom of this world: there being, for example, a peculiar energy and power, which is the inspirer of poetry; another, of geometry; and so a separate power, to remind us of each of the arts and professions of this kind. Lastly, many Greek writers have been of opinion that the art of poetry cannot exist without madness; whence also it is several times related in their histories, that those whom they call poets were suddenly filled with a kind of spirit of madness. And what are we to say also of those whom they call diviners, from whom, by the working of those demons who have the mastery over them, answers are given in carefully constructed verses? Those persons, too, whom they term Magi or Malevolent, frequently, by invoking demons over boys of tender years, have made them repeat poetical compositions which were the admiration and amazement of all. Now these effects we are to suppose are brought about in the following manner: As holy and immaculate souls, after devoting themselves to God with all affection and purity, and after preserving themselves free from all contagion of evil spirits, and after being purified by lengthened abstinence, and imbued with holy and religious training, assume by this means a portion of divinity, and earn the grace of prophecy, and other divine gifts; so also are we to suppose that those who place themselves in the way of the opposing powers, i.e., who purposely admire and adopt their manner of life and habits, receive their inspiration, and become partakers of their wisdom and doctrine. And the result of this is, that they are filled with the working of those spirits to whose service they have subjected themselves.
4. With respect to those, indeed, who teach differently regarding Christ from what the rule of Scripture allows, it is no idle task to ascertain whether it is from a treacherous purpose that these opposing powers, in their struggles to prevent a belief in Christ, have devised certain fabulous and impious doctrines; or whether, on hearing the word of Christ, and not being able to cast it forth from the secrecy of their conscience, nor yet to retain it pure and holy, they have, by means of vessels that were convenient to their use, and, so to speak, through their prophets, introduced various errors contrary to the rule of Christian truth. Now we are to suppose rather that apostate and refugee powers, which have departed from God out of the very wickedness of their mind and will, or from envy of those for whom there is prepared (on their becoming acquainted with the truth) an ascent to the same rank, whence they themselves had fallen, did, in order to prevent any progress of that kind, invent these errors and delusions of false doctrine. It is then clearly established, by many proofs, that while the soul of man exists in this body, it may admit different energies, i.e., operations, from a diversity of good and evil spirits. Now, of wicked spirits there is a twofold mode of operation: i.e., when they either take complete and entire possession of the mind, so as to allow their captives the power neither of understanding nor feeling; as, for instance, is the case with those commonly called possessed, whom we see to be deprived of reason, and insane (such as those were who are related in the Gospel to have been cured by the Saviour); or when by their wicked suggestions they deprave a sentient and intelligent soul with thoughts of various kinds, persuading it to evil, of which Judas is an illustration, who was induced at the suggestion of the devil to commit the crime of treason, according to the declaration of Scripture, that “the devil had already put it into the heart of Judas Iscariot to betray him.”
But a man receives the energy, i.e., the working, of a good spirit, when he is stirred and incited to good, and is inspired to heavenly or divine things; as the holy angels and God Himself wrought in the prophets, arousing and exhorting them by their holy suggestions to a better course of life, yet so, indeed, that it remained within the will and judgment of the individual, either to be willing or unwilling to follow the call to divine and heavenly things. And from this manifest distinction, it is seen how the soul is moved by the presence of a better spirit, i.e., if it encounter no perturbation or alienation of mind whatever from the impending inspiration, nor lose the free control of its will; as, for instance, is the case with all, whether prophets or apostles, who ministered to the divine responses without any perturbation of mind. Now, that by the suggestions of a good spirit the memory of man is aroused to the recollection of better things, we have already shown by previous instances, when we mentioned the cases of Mordecai and Artaxerxes.
5. This too, I think, should next be inquired into, viz., what are the reasons why a human soul is acted on at one time by good (spirits), and at another by bad: the grounds of which I suspect to be older than the bodily birth of the individual, as John (the Baptist) showed by his leaping and exulting in his mother's womb, when the voice of the salutation of Mary reached the ears of his mother Elisabeth; and as Jeremiah the prophet declares, who was known to God before he was formed in his mother's womb, and before he was born was sanctified by Him, and while yet a boy received the grace of prophecy. And again, on the other hand it is shown beyond a doubt, that some have been possessed by hostile spirits from the very beginning of their lives: i.e., some were born with an evil spirit; and others, according to credible histories, have practised divination from childhood. Others have been under the influence of the demon called Python, i.e., the ventriloquial spirit, from the commencement of their existence. To all which instances, those who maintain that everything in the world is under the administration of Divine Providence (as is also our own belief), can, as it appears to me, give no other answer, so as to show that no shadow of injustice rests upon the divine government, than by holding that there were certain causes of prior existence, in consequence of which the souls, before their birth in the body, contracted a certain amount of guilt in their sensitive nature, or in their movements, on account of which they have been judged worthy by Divine Providence of being placed in this condition. For a soul is always in possession of free-will, as well when it is in the body as when it is without it; and freedom of will is always directed either to good or evil. Nor can any rational and sentient being, i.e., a mind or soul, exist without some movement either good or bad. And it is probable that these movements furnish grounds for merit even before they do anything in this world; so that on account of these merits or grounds they are, immediately on their birth, and even before it, so to speak, assorted by Divine Providence for the endurance either of good or evil.
