Summa Theologica, Part I (Prima Pars) From the Complete...

Objection 1: It would seem that there is no sorrow in the demons. For since sorrow and joy are opposites, they cannot be together in the same subject. But there is joy in the demons: for Augustine writing against the Maniches (De Gen. Contra Manich. ii, 17) says: "The devil has power over them who despise God's commandments, and he rejoices over this sinister power." Therefore there is no sorrow in the demons.

Obj. 2: Further, sorrow is the cause of fear, for those things cause fear while they are future, which cause sorrow when they are present. But there is no fear in the demons, according to Job 41:24, "Who was made to fear no one." Therefore there is no grief in the demons.

On the contrary, The demon's sin is greater than man's sin. But man is punished with sorrow on account of the pleasure taken in sin, according to Apoc. 18:7, "As much as she hath glorified herself, and lived in delicacies, so much torment and sorrow give ye to her." Consequently much more is the devil punished with the grief of sorrow, because he especially glorified himself.

I answer that, Fear, sorrow, joy, and the like, so far as they are passions, cannot exist in the demons; for thus they are proper to the sensitive appetite, which is a power in a corporeal organ. According, however, as they denote simple acts of the will, they can be in the demons. And it must be said that there is sorrow in them; because sorrow, as denoting a simple act of the will, is nothing else than the resistance of the will to what is, or to what is not. Now it is evident that the demons would wish many things not to be, which are, and others to be, which are not: for, out of envy, they would wish others to be damned, who are saved. Consequently, sorrow must be said to exist in them: and especially because it is of the very notion of punishment for it to be repugnant to the will. Moreover, they are deprived of happiness, which they desire naturally; and their wicked will is curbed in many respects.

Reply Obj. 1: Joy and sorrow about the same thing are opposites, but not about different things. Hence there is nothing to hinder a man from being sorry for one thing, and joyful for another; especially so far as sorrow and joy imply simple acts of the will; because, not merely in different things, but even in one and the same thing, there can be something that we will, and something that we will not.

Reply Obj. 2: As there is sorrow in the demons over present evil, so also there is fear of future evil. Now when it is said, "He was made to fear no one," this is to be understood of the fear of God which restrains from sin. For it is written elsewhere that "the devils believe and tremble" (James 2:19).

Reply Obj. 3: To be sorry for the evil of sin on account of the sin bears witness to the goodness of the will, to which the evil of sin is opposed. But to be sorry for the evil of punishment, or for the evil of sin on account of the punishment, bears witness to the goodness of nature, to which the evil of punishment is opposed. Hence Augustine says (De Civ. Dei xix, 13), that "sorrow for good lost by punishment, is the witness to a good nature." Consequently, since the demon has a perverse and obstinate will, he is not sorry for the evil of sin. _______________________

I answer that, The angels in their own nature stand midway between God and men. Now the order of Divine providence so disposes, that it procures the welfare of the inferior orders through the superior. But man's welfare is disposed by Divine providence in two ways: first of all, directly, when a man is brought unto good and withheld from evil; and this is fittingly done through the good angels. In another way, indirectly, as when anyone assailed is exercised by fighting against opposition. It was fitting for this procuring of man's welfare to be brought about through the wicked spirits, lest they should cease to be of service in the natural order. Consequently a twofold place of punishment is due to the demons: one, by reason of their sin, and this is hell; and another, in order that they may tempt men, and thus the darksome atmosphere is their due place of punishment.

Now the procuring of men's salvation is prolonged even to the judgment day: consequently, the ministry of the angels and wrestling with demons endure until then. Hence until then the good angels are sent to us here; and the demons are in this dark atmosphere for our trial: although some of them are even now in hell, to torment those whom they have led astray; just as some of the good angels are with the holy souls in heaven. But after the judgment day all the wicked, both men and angels, will be in hell, and the good in heaven.

Reply Obj. 3: Some have maintained that the pain of sense for demons and souls is postponed until the judgment day: and that the beatitude of the saints is likewise postponed until the judgment day. But this is erroneous, and contrary to the teaching of the Apostle (2 Cor. 5:1): "If our earthly house of this habitation be dissolved, we have a house in heaven." Others, again, while not admitting the same of souls, admit it as to demons. But it is better to say that the same judgment is passed upon wicked souls and wicked angels, even as on good souls and good angels.

Consequently, it must be said that, although a heavenly place belongs to the glory of the angels, yet their glory is not lessened by their coming to us, for they consider that place to be their own; in the same way as we say that the bishop's honor is not lessened while he is not actually sitting on his throne. In like manner it must be said, that although the demons are not actually bound within the fire of hell while they are in this dark atmosphere, nevertheless their punishment is none the less; because they know that such confinement is their due. Hence it is said in a gloss upon James 3:6: "They carry fire of hell with them wherever they go." Nor is this contrary to what is said (Luke 8:31), "They besought the Lord not to cast them into the abyss"; for they asked for this, deeming it to be a punishment for them to be cast out of a place where they could injure men. Hence it is stated, "They [Vulg. 'He'] besought Him that He would not expel them [Vulg. 'him'] out of the country" (Mark 5:10). _______________________
