Reply to Objection 4: It is true to say that there is a middle time between every two instants, so far as time is continuous, as it is proved Phys. vi, text. 2. But in the angels, who are not subject to the heavenly movement, which is primarily measured by continuous time, time is taken to mean the succession of their mental acts, or of their affections. So the first instant in the angels is understood to respond to the operation of the angelic mind, whereby it introspects itself by its evening knowledge because on the first day evening is mentioned, but not morning. This operation was good in them all. From such operation some of them were converted to the praise of the Word by their morning knowledge while others, absorbed in themselves, became night, "swelling up with pride," as Augustine says (Gen. ad lit. iv, 24). Hence the first act was common to them all; but in their second they were separated. Consequently they were all of them good in the first instant; but in the second the good were set apart from the wicked.
Whether the highest angel among those who sinned was the highest of all?
Objection 1: It would seem that the highest among the angels who sinned was not the highest of all. For it is stated ( Ezech. 28:14 ): "Thou wast a cherub stretched out, and protecting, and I set thee in the holy mountain of God." Now the order of the Cherubim is under the order of the Seraphim, as Dionysius says (Coel. Hier. vi, vii). Therefore, the highest angel among those who sinned was not the highest of all.
Objection 2: Further, God made intellectual nature in order that it might attain to beatitude. If therefore the highest of the angels sinned, it follows that the Divine ordinance was frustrated in the noblest creature which is unfitting.
Objection 3: Further, the more a subject is inclined towards anything, so much the less can it fall away from it. But the higher an angel is, so much the more is he inclined towards God. Therefore so much the less can he turn away from God by sinning. And so it seems that the angel who sinned was not the highest of all, but one of the lower angels.
On the contrary, Gregory (Hom. xxxiv in Ev.) says that the chief angel who sinned, "being set over all the hosts of angels, surpassed them in brightness, and was by comparison the most illustrious among them."
I answer that, Two things have to be considered in sin, namely, the proneness to sin, and the motive for sinning. If, then, in the angels we consider the proneness to sin, it seems that the higher angels were less likely to sin than the lower. On this account Damascene says (De Fide Orth. ii), that the highest of those who sinned was set over the terrestrial order. This opinion seems to agree with the view of the Platonists, which Augustine quotes (De Civ. Dei vii, 6,7; x, 9,10,11). For they said that all the gods were good; whereas some of the demons were good, and some bad; naming as 'gods' the intellectual substances which are above the lunar sphere, and calling by the name of "demons" the intellectual substances which are beneath it, yet higher than men in the order of nature. Nor is this opinion to be rejected as contrary to faith; because the whole corporeal creation is governed by God through the angels, as Augustine says (De Trin. iii, 4,5). Consequently there is nothing to prevent us from saying that the lower angels were divinely set aside for presiding over the lower bodies, the higher over the higher bodies; and the highest to stand before God. And in this sense Damascene says (De Fide Orth. ii) that they who fell were of the lower grade of angels; yet in that order some of them remained good.
But if the motive for sinning be considered, we find that it existed in the higher angels more than in the lower. For, as has been said (A[2]), the demons' sin was pride; and the motive of pride is excellence, which was greater in the higher spirits. Hence Gregory says that he who sinned was the very highest of all. This seems to be the more probable view: because the angels' sin did not come of any proneness, but of free choice alone. Consequently that argument seems to have the more weight which is drawn from the motive in sinning. Yet this must not be prejudicial to the other view; because there might be some motive for sinning in him also who was the chief of the lower angels.
Reply to Objection 1: Cherubim is interpreted "fulness of knowledge," while "Seraphim" means "those who are on fire," or "who set on fire." Consequently Cherubim is derived from knowledge; which is compatible with mortal sin; but Seraphim is derived from the heat of charity, which is incompatible with mortal sin. Therefore the first angel who sinned is called, not a Seraph, but a Cherub.
Reply to Objection 2: The Divine intention is not frustrated either in those who sin, or in those who are saved; for God knows beforehand the end of both; and He procures glory from both, saving these of His goodness, and punishing those of His justice. But the intellectual creature, when it sins, falls away from its due end. Nor is this unfitting in any exalted creature; because the intellectual creature was so made by God, that it lies within its own will to act for its end.
Reply to Objection 3: However great was the inclination towards good in the highest angel, there was no necessity imposed upon him: consequently it was in his power not to follow it.
Whether the sin of the highest angel was the cause of the others sinning?
Objection 1: It would seem that the sin of the highest angel was not the cause of the others sinning. For the cause precedes the effect. But, as Damascene observes (De Fide Orth. ii), they all sinned at one time. Therefore the sin of one was not the cause of the others' sinning.
Objection 2: Further, an angel's first sin can only be pride, as was shown above (A[2]). But pride seeks excellence. Now it is more contrary to excellence for anyone to be subject to an inferior than to a superior; and so it does not appear that the angels sinned by desiring to be subject to a higher angel rather than to God. Yet the sin of one angel would have been the cause of the others sinning, if he had induced them to be his subjects. Therefore it does not appear that the sin of the highest angel was the cause of the others sinning.
Objection 3: Further, it is a greater sin to wish to be subject to another against God, than to wish to be over another against God; because there is less motive for sinning. If, therefore, the sin of the foremost angel was the cause of the others sinning, in that he induced them to subject themselves to him, then the lower angels would have sinned more deeply than the highest one; which is contrary to a gloss on Ps. 103:26 : "This dragon which Thou hast formed---He who was the more excellent than the rest in nature, became the greater in malice." Therefore the sin of the highest angel was not the cause of the others sinning.
On the contrary, It is said ( Apoc. 12:4 ) that the dragon "drew" with him "the third part of the stars of heaven."
I answer that, The sin of the highest angel was the cause of the others sinning; not as compelling them, but as inducing them by a kind of exhortation. A token thereof appears in this, that all the demons are subjects of that highest one; as is evident from our Lord's words: "Go [Vulg. 'Depart from Me'], you cursed, into everlasting fire, which was prepared for the devil and his angels" ( Mat. 25:41 ). For the order of Divine justice exacts that whosoever consents to another's evil suggestion, shall be subjected to him in his punishment; according to ( 2 Pet. 2:19 ): "By whom a man is overcome, of the same also he is the slave."
Reply to Objection 1: Although the demons all sinned in the one instant, yet the sin of one could be the cause of the rest sinning. For the angel needs no delay of time for choice, exhortation, or consent, as man, who requires deliberation in order to choose and consent, and vocal speech in order to exhort; both of which are the work of time. And it is evident that even man begins to speak in the very instant when he takes thought; and in the last instant of speech, another who catches his meaning can assent to what is said; as is especially evident with regard to primary concepts, "which everyone accepts directly they are heard" [*Boethius, De Hebdom.].
Taking away, then, the time for speech and deliberation which is required in us; in the same instant in which the highest angel expressed his affection by intelligible speech, it was possible for the others to consent thereto.
Reply to Objection 2: Other things being equal, the proud would rather be subject to a superior than to an inferior. Yet he chooses rather to be subject to an inferior than to a superior, if he can procure an advantage under an inferior which he cannot under a superior. Consequently it was not against the demons' pride for them to wish to serve an inferior by yielding to his rule; for they wanted to have him as their prince and leader, so that they might attain their ultimate beatitude of their own natural powers; especially because in the order of nature they were even then subject to the highest angel.
Reply to Objection 3: As was observed above (Q[62], A[6]), an angel has nothing in him to retard his action, and with his whole might he is moved to whatsoever he is moved, be it good or bad. Consequently since the highest angel had greater natural energy than the lower angels, he fell into sin with intenser energy, and therefore he became the greater in malice.
Whether those who sinned were as many as those who remained firm?
Objection 1: It would seem that more angels sinned than stood firm. For, as the Philosopher says (Ethic. ii, 6): "Evil is in many, but good is in few."
Objection 2: Further, justice and sin are to be found in the same way in men and in angels. But there are more wicked men to be found than good; according to Eccles. 1:15 : "The number of fools is infinite." Therefore for the same reason it is so with the angels.
Objection 3: Further, the angels are distinguished according to persons and orders. Therefore if more angelic persons stood firm, it would appear that those who sinned were not from all the orders.
