Treatise on the Government of Creatures (Questions 103-119)
We now consider the assaults of the demons. Under this head there are five points of inquiry: (1) Whether men are assailed by the demons? (2) Whether to tempt is proper to the devil? (3) Whether all the sins of men are to be set down to the assaults or temptations of the demons? (4) Whether they can work real miracles for the purpose of leading men astray? (5) Whether the demons who are overcome by men, are hindered from making further assaults?
We proceed thus to the First Article:ó
Objection 1. It would seem that men are not assailed by the demons. For angels are sent by God to guard man. But demons are not sent by God: for the demonsí intention is the loss of souls; whereas Godís is the salvation of souls. Therefore demons are not deputed to assail man.
Obj. 2. Further, it is not a fair fight, for the weak to be set against the strong, and the ignorant against the astute. But men are weak and ignorant, whereas the demons are strong and astute. It is not therefore to be permitted by God, the author of all justice, that men should be assailed by demons.
Obj. 3. Further, the assaults of the flesh and the world are enough for manís exercise. But God permits His elect to be assailed that they may be exercised. Therefore there is no need for them to be assailed by the demons.
On the contrary, The Apostle says (Eph. vi. 12): Our wrestling is not against flesh and blood; but against Principalities and Powers, against the rulers of the world of this darkness, against the spirits of wickedness in the high places.
I answer that, Two things may be considered in the assault of the demonsóthe assault itself, and the ordering thereof. The assault itself is due to the malice of the demons, who through envy endeavor to hinder manís progress; and through pride usurp a semblance of Divine power, by deputing certain ministers to assail man, as the angels of God in their various offices minister to manís salvation. But the ordering of the assault is from God, Who knows how to make orderly use of evil by ordering it to good. On the other hand, in regard to the angels, both their guardianship and the ordering thereof are to be referred to God as their first author.
Reply Obj. 1. The wicked angels assail men in two ways. Firstly by instigating them to sin; and thus they are not sent by God to assail us, but are sometimes permitted to do so according to Godís just judgments. But sometimes their assault is a punishment to man: and thus they are sent by God; as the lying spirit was sent to punish Achab, King of Israel, as is related in 3 Kings xxii. 20. For punishment is referred to God as its first author. Nevertheless the demons who are sent to punish, do so with an intention other than that for which they are sent; for they punish from hatred or envy; whereas they are sent by God on account of His justice.
Reply Obj. 2. In order that the conditions of the fight be not unequal, there is as regards man the promised recompense, to be gained principally through the grace of God, secondarily through the guardianship of the angels. Wherefore (4 Kings vi. 16), Eliseus said to his servant: Fear not, for there are more with us than with them.
Reply Obj. 3. The assault of the flesh and the world would suffice for the exercise of human weakness: but it does not suffice for the demonís malice, which makes use of both the above in assailing men. But by the Divine ordinance this tends to the glory of the elect.
We proceed thus to the Second Article:ó
Objection 1. It would seem that to tempt is not proper to the devil. For God is said to tempt, according to Genesis xxii. 1, God tempted Abraham. Moreover man is tempted by the flesh and the world. Again, man is said to tempt God, and to tempt man. Therefore it is not proper to the devil to tempt.
Obj. 2. Further, to tempt is a sign of ignorance. But the demons know what happens among men. Therefore the demons do not tempt.
Obj. 3. Further, temptation is the road to sin. Now sin dwells in the will. Since therefore the demons cannot change manís will, as appears from what has been said above (Q. 111, A. 2), it seems that it is not in their province to tempt.
On the contrary, It is written (1 Thess. iii. 5): Lest perhaps he that tempteth should have tempted you: to which the gloss adds, that is, the devil, whose office it is to tempt.
I answer that, To tempt is, properly speaking, to make trial of something. Now we make trial of something in order to know something about it: hence the immediate end of every tempter is knowledge. But sometimes another end, either good or bad, is sought to be acquired through that knowledge; a good end, when, for instance, one desires to know of someone, what sort of a man he is as to knowledge, or virtue, with a view to his promotion; a bad end, when that knowledge is sought with the purpose of deceiving or ruining him.
From this we can gather how various beings are said to tempt in various ways. For man is said to tempt, sometimes indeed merely for the sake of knowing something; and for this reason it is a sin to tempt God; for man, being uncertain as it were, presumes to make an experiment of Godís power. Sometimes too he tempts in order to help, sometimes in order to hurt. The devil, however, always tempts in order to hurt by urging man into sin. In this sense it is said to be his proper office to tempt: for though at times man tempts thus, he does this as minister of the devil. God is said to tempt that He may know, in the same sense as that is said to know which makes others to know. Hence it is written (Deut. xiii. 3): The Lord your God trieth you, that it may appear whether you love him.
The flesh and the world are said to tempt as the instruments or matter of temptations; inasmuch as one can know what sort of man someone is, according as he follows or resists the desires of the flesh, and according as he despises worldly advantages and adversity: of which things the devil also makes use in tempting.
Thus the reply to the first objection is clear.
Reply Obj. 2. The demons know what happens outwardly among men; but the inward disposition of man God alone knows, Who is the weigher of spirits (Prov. xvi. 2). It is this disposition that makes man more prone to one vice than to another: hence the devil tempts, in order to explore this inward disposition of man, so that he may tempt him to that vice to which he is most prone.
Reply Obj. 3. Although a demon cannot change the will, yet, as stated above (Q. 111, A. 3), he can change the inferior powers of man, in a certain degree: by which powers, though the will cannot be forced, it can nevertheless be inclined.
We proceed thus to the Third Article:ó
Objection 1. It would seem that all sins are due to the temptation of the devil. For Dionysius says (Div. Nom. iv) that the multitude of demons is the cause of all evils, both to themselves and to others. And Damascene says (De Fide Orth. ii. 4) that all malice and all uncleanness have been devised by the devil.
Obj. 2. Further, of every sinner can be said what the Lord said of the Jews (Jo. viii. 44): You are of your father the devil. But this was in as far as they sinned through the devilís instigation. Therefore every sin is due to the devilís instigation.
Obj. 3. Further, as angels are deputed to guard men, so demons are deputed to assail men. But every good thing we do is due to the suggestion of the good angels: because the Divine gifts are borne to us by the angels. Therefore all the evil we do, is due to the instigation of the devil.
On the contrary, It is written (De Eccl. Dogmat. xlix): Not all our evil thoughts are stirred up by the devil, but sometimes they arise from the movement of our free-will.
I answer that, One thing can be the cause of another in two ways; directly and indirectly. Indirectly as when an agent is the cause of a disposition to a certain effect, it is said to be the occasional and indirect cause of that effect: for instance, we might say that he who dries the wood is the cause of the wood burning. In this way we must admit that the devil is the cause of all our sins; because he it was who instigated the first man to sin, from whose sin there resulted a proneness to sin in the whole human race: and in this sense we must take the words of Damascene and Dionysius.
But a thing is said to be the direct cause of something, when its action tends directly thereunto. And in this way the devil is not the cause of every sin: for all sins are not committed at the devilís instigation, but some are due to the free-will and the corruption of the flesh. For, as Origen says (Peri Archon iii), even if there were no devil, men would have the desire for food and love and such like pleasures; with regard to which many disorders may arise unless those desires are curbed by reason, especially if we presuppose the corruption of our natures. Now it is in the power of the free-will to curb this appetite and keep it in order. Consequently there is no need for all sins to be due to the instigation of the devil. But those sins which are due thereto man perpetrates through being deceived by the same blandishments as were our first parents, as Isidore says (De Summo Bono ii).
Thus the answer to the first objection is clear.
Reply Obj. 2. When man commits sin without being thereto instigated by the devil, he nevertheless becomes a child of the devil thereby, in so far as he imitates him who was the first to sin.
Reply Obj. 3. Man can of his own accord fall into sin: but he cannot advance in merit without the Divine assistance, which is borne to man by the ministry of the angels. For this reason the angels take part in all our good works: whereas all our sins are not due to the demonsí instigation. Nevertheless there is no kind of sin which is not sometimes due to the demonsí suggestion.
We proceed thus to the Fourth Article:ó
Objection 1. It would seem that the demons cannot lead men astray by means of real miracles. For the activity of the demons will show itself especially in the works of Antichrist. But as the Apostle says (2 Thess. ii. 9), his coming is according to the working of Satan, in all power, and signs, and lying wonders. Much more therefore at other times do the demons perform lying wonders.
Obj. 2. Further, true miracles are wrought by some corporeal change. But demons are unable to change the nature of a body; for Augustine says (De Civ. Dei xviii. 18): I cannot believe that the human body can receive the limbs of a beast by means of a demonís art or power. Therefore the demons cannot work real miracles.
Obj. 3. Further, an argument is useless which may prove both ways. If therefore real miracles can be wrought by demons, to persuade one of what is false, they will be useless to confirm the teaching of the faith. This is unfitting; for it is written (Mk. xvi. 20): The Lord working withal, and confirming the word with signs that followed.
On the contrary, Augustine says (Q. 83) [Lib. xxi. Sent., sent. 4, among the supposititious works of St. Augustine]: Often by means of the magic art miracles are wrought like those which are wrought by the servants of God.
I answer that, As is clear from what has been said above (Q. 110, A. 4), if we take a miracle in the strict sense, the demons cannot work miracles, nor can any creature, but God alone: since in the strict sense a miracle is something done outside the order of the entire created nature, under which order every power of a creature is contained. But sometimes miracle may be taken in a wide sense, for whatever exceeds the human power and experience. And thus demons can work miracles, that is, things which rouse manís astonishment, by reason of their being beyond his power and outside his sphere of knowledge. For even a man by doing what is beyond the power and knowledge of another, leads him to marvel at what he has done, so that in a way he seems to that man to have worked a miracle.
It is to be noted, however, that although these works of demons which appear marvelous to us are not real miracles, they are sometimes nevertheless something real. Thus the magicians of Pharaoh by the demonsí power produced real serpents and frogs. And when fire came down from heaven and at one blow consumed Jobís servants and sheep; when the storm struck down his house and with it his childrenóthese were the work of Satan, not phantoms; as Augustine says (De Civ. Dei xx. 19).
Reply Obj. 1. As Augustine says in the same place, the works of Antichrist may be called lying wonders, either because he will deceive menís senses by means of phantoms, so that he will not really do what he will seem to do; or because, if he work real prodigies, they will lead those into falsehood who believe in him.
Reply Obj. 2. As we have said above (Q. 110, A. 2), corporeal matter does not obey either good or bad angels at their will, so that demons be able by their power to transmute matter from one form to another; but they can employ certain seeds that exist in the elements of the world, in order to produce these effects, as Augustine says (De Trin. iii. 8, 9). Therefore it must be admitted that all the transformation of corporeal things which can be produced by certain natural powers, to which we must assign the seeds above mentioned, can alike be produced by the operation of the demons, by the employment of these seeds; such as the transformation of certain things into serpents or frogs, which can be produced by putrefaction. On the contrary, those transformations which cannot be produced by the power of nature, cannot in reality be effected by the operation of the demons; for instance, that the human body be changed into the body of a beast, or that the body of a dead man return to life. And if at times something of this sort seems to be effected by the operation of demons, it is not real but a mere semblance of reality.
Now this may happen in two ways. Firstly, from within; in this way a demon can work on manís imagination and even on his corporeal senses, so that something seems otherwise that it is, as explained above (Q. 111, AA. 3, 4). It is said indeed that this can be done sometimes by the power of certain bodies. Secondly, from without: for just as he can from the air form a body of any form and shape, and assume it so as to appear in it visibly: so, in the same way he can clothe any corporeal thing with any corporeal form, so as to appear therein. This is what Augustine says (De Civ. Dei xviii. 18): manís imagination, which whether thinking or dreaming, takes the forms of an innumerable number of things, appears to other menís senses, as it were embodied in the semblance of some animal. This not to be understood as though the imagination itself or the images formed therein were identified with that which appears embodied to the senses of another man: but that the demon, who forms an image in a manís imagination, can offer the same picture to another manís senses.
Reply Obj. 3. As Augustine says (QQ. 83, qu. 79): When magicians do what holy men do, they do it for a different end and by a different right. The former do it for their own glory; the latter, for the glory of God: the former, by certain private compacts; the latter by the evident assistance and command of God, to Whom every creature is subject.
We proceed thus to the Fifth Article:ó
Objection 1. It would seem that a demon who is overcome by a man, is not for that reason hindered from any further assault. For Christ overcame the tempter most effectively. Yet afterwards the demon assailed Him by instigating the Jews to kill Him. Therefore it is not true that the devil when conquered ceases his assaults.
Obj. 2. Further, to inflict punishment on one who has been worsted in a fight, is to incite him to a sharper attack. But this is not befitting Godís mercy. Therefore the conquered demons are not prevented from further assaults.
On the contrary, It is written (Matt. iv. 11): Then the devil left Him, i.e., Christ Who overcame.
I answer that, Some say that when once a demon has been overcome he can no more tempt any man at all, neither to the same nor to any other sin. And others say that he can tempt others, but not the same man. This seems more probable as long as we understand it to be so for a certain definite time: wherefore (Luke iv. 13) it is written: All temptation being ended, the devil departed from Him for a time. There are two reasons for this. One is on the part of Godís clemency; for as Chrysostom says (Super Matt. Hom. v) [in the Opus Imperfectum, among his supposititious works], the devil does not tempt man for just as long as he likes, but for as long as God allows; for although He allows him to tempt for a short time, He orders him off on account of our weakness. The other reason is taken from the astuteness of the devil. As to this, Ambrose says on Luke iv. 13: The devil is afraid of persisting, because he shrinks from frequent defeat. That the devil does nevertheless sometimes return to the assault, is apparent from Mat. xii. 44: I will return into my house from whence I came out.
From what has been said, the objections can easily be solved.
