Of the Assaults of the Demons

Of the Assaults of the Demons — St. Thomas Aquinas asks: Whether men are assailed by the demons?; Whether to tempt is proper to the devil?; Whether all sins are due to the temptation of the devil?; Whether demons can lead men astray by means of real miracles?; Whether a demon who is overcome by man, is for this reason hindered from making further assaults?.

We now consider the assaults of the demons. Under this head there are five points of inquiry:

Article 1: Whether men are assailed by the demons?

The Apostle says (Eph. 6:12): "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."

Two things may be considered in the assault of the demons---the assault itself, and the ordering thereof. The assault itself is due to the malice of the demons, who through envy endeavor to hinder man's 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 man's 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.

Article 2: Whether to tempt is proper to the devil?

It is written (1 Thess. 3:5): "Lest perhaps he that tempteth should have tempted you": to which the gloss adds, "that is, the devil, whose office it is to tempt."

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 God's 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 thought 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 (Dt. 13:3): "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.

Article 3: Whether all sins are due to the temptation of the devil?

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."

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 devil's 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.

Article 4: Whether demons can lead men astray by means of real miracles?

Augustine says (; [*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."

As is clear from what has been said above (), 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 man's 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 demons' power produced real serpents and frogs. And "when fire came down from heaven and at one blow consumed Job's servants and sheep; when the storm struck down his house and with it his children---these were the work of Satan, not phantoms"; as Augustine says (De Civ. Dei xx, 19).

Article 5: Whether a demon who is overcome by man, is for this reason hindered from making further assaults?

It is written (Mat. 4:11): "Then the devil left Him," i.e. Christ Who overcame.

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 (Lk. 4:13) 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 God's 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 Lk. 4:13: "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. 12:44: "I will return into my house from whence I came out."

From what has been said, the objections can easily be solved.
