[I.q.112.a.1.arg.1] It would seem that the angels are not sent on works of ministry. For every mission is to some determinate place. But intellectual actions do not determine a place, for intellect abstracts from the "here" and "now." Since therefore the angelic actions are intellectual, it appears that the angels are not sent to perform their own actions.

[I.q.112.a.1.arg.2] Further, the empyrean heaven is the place that beseems the angelic dignity. Therefore if they are sent to us in ministry, it seems that something of their dignity would be lost; which is unseemly.

[I.q.112.a.1.arg.3] Further, external occupation hinders the contemplation of wisdom; hence it is said: "He that is less in action, shall receive wisdom" (Sirach 38:25). So if some angels are sent on external ministrations, they would seemingly be hindered from contemplation. But the whole of their beatitude consists in the contemplation of God. So if they were sent, their beatitude would be lessened; which is unfitting.

[I.q.112.a.1.arg.4] Further, to minister is the part of an inferior; hence it is written (Luke 22:27): "Which is the greater, he that sitteth at table, or he that serveth? is not he that sitteth at table?" But the angels are naturally greater than we are. Therefore they are not sent to administer to us.

[I.q.112.a.1.sc] It is written (Exodus 23:20): "Behold I will send My angels who shall go before thee."

[I.q.112.a.1.co] From what has been said above (Question 108, Article 6), it may be shown that some angels are sent in ministry by God. For, as we have already stated (43, 1), in treating of the mission of the Divine Persons, he is said to be sent who in any way proceeds from another so as to begin to be where he was not, or to be in another way, where he already was. Thus the Son, or the Holy Ghost is said to be sent as proceeding from the Father by origin; and begins to be in a new way, by grace or by the nature assumed, where He was before by the presence of His Godhead; for it belongs to God to be present everywhere, because, since He is the universal agent, His power reaches to all being, and hence He exists in all things (8, 1). An angel's power, however, as a particular agent, does not reach to the whole universe, but reaches to one thing in such a way as not to reach another; and so he is "here" in such a manner as not to be "there." But it is clear from what was above stated (110, 1), that the corporeal creature is governed by the angels. Hence, whenever an angel has to perform any work concerning a corporeal creature, the angel applies himself anew to that body by his power; and in that way begins to be there afresh. Now all this takes place by Divine command. Hence it follows that an angel is sent by God.

Yet the action performed by the angel who is sent, proceeds from God as from its first principle, at Whose nod and by Whose authority the angels work; and is reduced to God as to its last end. Now this is what is meant by a minister: for a minister is an intelligent instrument; while an instrument is moved by another, and its action is ordered to another. Hence angels' actions are called 'ministries'; and for this reason they are said to be sent in ministry.

[I.q.112.a.1.ad.1] An operation can be intellectual in two ways. In one way, as dwelling in the intellect itself, as contemplation; such an operation does not demand to occupy a place; indeed, as Augustine says (De Trin. iv, 20): "Even we ourselves as mentally tasting something eternal, are not in this world." In another sense an action is said to be intellectual because it is regulated and commanded by some intellect; in that sense the intellectual operations evidently have sometimes a determinate place.

[I.q.112.a.1.ad.2] The empyrean heaven belongs to the angelic dignity by way of congruity; forasmuch as it is congruous that the higher body should be attributed to that nature which occupies a rank above bodies. Yet an angel does not derive his dignity from the empyrean heaven; so when he is not actually in the empyrean heaven, nothing of his dignity is lost, as neither does a king lessen his dignity when not actually sitting on his regal throne, which suits his dignity.

[I.q.112.a.1.ad.3] In ourselves the purity of contemplation is obscured by exterior occupation; because we give ourselves to action through the sensitive faculties, the action of which when intense impedes the action of the intellectual powers. An angel, on the contrary, regulates his exterior actions by intellectual operation alone. Hence it follows that his external occupations in no respect impede his contemplation; because given two actions, one of which is the rule and the reason of the other, one does not hinder but helps the other. Wherefore Gregory says (Moral. ii) that "the angels do not go abroad in such a manner as to lose the delights of inward contemplation."

[I.q.112.a.1.ad.4] In their external actions the angels chiefly minister to God, and secondarily to us; not because we are superior to them, absolutely speaking, but because, since every man or angel by cleaving to God is made one spirit with God, he is thereby superior to every creature. Hence the Apostle says (Philippians 2:3): "Esteeming others better than themselves."

[I.q.112.a.4.arg.1] It would seem that all the angels of the second hierarchy are sent. For all the angels either assist, or minister, according to Daniel 7:10. But the angels of the second hierarchy do not assist; for they are enlightened by the angels of the first hierarchy, as Dionysius says (Coel. Hier. viii). Therefore all the angels of the second hierarchy are sent in ministry.

[I.q.112.a.4.arg.2] Further, Gregory says (Moral. xvii) that "there are more who minister than who assist." This would not be the case if the angels of the second hierarchy were not sent in ministry. Therefore all the angels of the second hierarchy are sent to minister.

[I.q.112.a.4.sc] Dionysius says (Coel. Hier. viii) that the "Dominations are above all subjection." But to be sent implies subjection. Therefore the dominations are not sent to minister.

[I.q.112.a.4.co] As above stated (1), to be sent to external ministry properly belongs to an angel according as he acts by Divine command in respect of any corporeal creature; which is part of the execution of the Divine ministry. Now the angelic properties are manifested by their names, as Dionysius says (Coel. Hier. vii); and therefore the angels of those orders are sent to external ministry whose names signify some kind of administration. But the name "dominations" does not signify any such administration, but only disposition and command in administering. On the other hand, the names of the inferior orders imply administration, for the "Angels" and "Archangels" are so called from "announcing"; the "Virtues" and "Powers" are so called in respect of some act; and it is right that the "Prince," according to what Gregory says (Hom. xxxiv in Evang.), "be first among the workers." Hence it belongs to these five orders to be sent to external ministry; not to the four superior orders.

[I.q.112.a.4.ad.1] The Dominations are reckoned among the ministering angels, not as exercising but as disposing and commanding what is to be done by others; thus an architect does not put his hands to the production of his art, but only disposes and orders what others are to do.

[I.q.112.a.4.ad.2] A twofold reason may be given in assigning the number of the assisting and ministering angels. For Gregory says that those who minister are more numerous than those who assist; because he takes the words (Daniel 7:10) "thousands of thousands ministered to Him," not in a multiple but in a partitive sense, to mean "thousands out of thousands"; thus the number of those who minister is indefinite, and signifies excess; while the number of assistants is finite as in the words added, "and ten thousand times a hundred thousand assisted Him." This explanation rests on the opinion of the Platonists, who said that the nearer things are to the one first principle, the smaller they are in number; as the nearer a number is to unity, the lesser it is than multitude. This opinion is verified as regards the number of orders, as six administer and three assist.

Dionysius, however, (Coel. Hier. xiv) declares that the multitude of angels surpasses all the multitude of material things; so that, as the superior bodies exceed the inferior in magnitude to an immeasurable degree, so the superior incorporeal natures surpass all corporeal natures in multitude; because whatever is better is more intended and more multiplied by God. Hence, as the assistants are superior to the ministers there will be more assistants than ministers. In this way, the words "thousands of thousands" are taken by way of multiplication, to signify "a thousand times a thousand." And because ten times a hundred is a thousand, if it were said "ten times a hundred thousand" it would mean that there are as many assistants as ministers: but since it is written "ten thousand times a hundred thousand," we are given to understand that the assistants are much more numerous than the ministers. Nor is this said to signify that this is the precise number of angels, but rather that it is much greater, in that it exceeds all material multitude. This is signified by the multiplication together of all the greatest numbers, namely ten, a hundred, and a thousand, as Dionysius remarks in the same passage.
