light, and by manifesting to him the truth concerning the state of nature, of grace, and of glory, as explained above.

Reply Obj. 3: The rational mind is formed immediately by God, either as the image from the exemplar, forasmuch as it is made to the image of God alone; or as the subject by the ultimate perfecting form: for the created mind is always considered to be unformed, except it adhere to the first truth; while the other kinds of enlightenment that proceed from man or angel, are, as it were, dispositions to this ultimate form.

Whether one angel moves another angel's will?

Objection 1: It would seem that one angel can move another angel's will. Because, according to Dionysius quoted above (A. 1), as one angel enlightens another, so does he cleanse and perfect another. But cleansing and perfecting seem to belong to the will: for the former seems to point to the stain of sin which appertains to will; while to be perfected is to obtain an end, which is the object of the will.

Therefore an angel can move another angel's will.

Obj. 2: Further, as Dionysius says (Coel. Hier. vii): "The names of the angels designate their properties." Now the Seraphim are so called because they "kindle" or "give heat": and this is by love which belongs to the will. Therefore one angel moves another angel's will.

Obj. 3: Further, the Philosopher says (De Anima iii, 11) that the higher appetite moves the lower. But as the intellect of the superior angel is higher, so also is his will. It seems, therefore, that the superior angel can change the will of another angel.

_On the contrary,_ To him it belongs to change the will, to whom it belongs to bestow righteousness: for righteousness is the rightness of the will. But God alone bestows righteousness. Therefore one angel cannot change another angel's will.

_I answer that,_ As was said above (Q. 105, A. 4), the will is changed in two ways; on the part of the object, and on the part of the power. On the part of the object, both the good itself which is the object of the will, moves the will, as the appetible moves the appetite; and he who points out the object, as, for instance, one who proves something to be good. But as we have said above (Q. 105, A. 4), other goods in a measure incline the will, yet nothing sufficiently moves the will save the universal good, and that is God.

And this good He alone shows, that it may be seen by the blessed, Who, when Moses asked: "Show me Thy glory," answered: "I will show thee all good" (Ex. 33:18, 19). Therefore an angel does not move the will sufficiently, either as the object or as showing the object. But he inclines the will as something lovable, and as manifesting some created good ordered to God's goodness. And thus he can incline the will to the love of the creature or of God, by way of persuasion.

But on the part of the power the will cannot be moved at all save by God. For the operation of the will is a certain inclination of the willer to the thing willed. And He alone can change this inclination, Who bestowed on the creature the power to will: just as that agent alone can change the natural inclination, which can give the power to which follows that natural inclination. Now God alone gave to the creature the power to will, because He alone is the author of the intellectual nature. Therefore an angel cannot move another angel's will.

Reply Obj. 1: Cleansing and perfecting are to be understood according to the mode of enlightenment. And since God enlightens by changing the intellect and will, He cleanses by removing defects of intellect and will, and perfects unto the end of the intellect and will. But the enlightenment caused by an angel concerns the intellect, as explained above (A. 1); therefore an angel is to be understood as cleansing from the defect of nescience in the intellect; and as perfecting unto the consummate end of the intellect, and this is the knowledge of truth. Thus Dionysius says (Eccl. Hier. vi): that "in the heavenly hierarchy the chastening of the inferior essence is an enlightening of things unknown, that leads them to more perfect knowledge." For instance, we might say that corporeal sight is cleansed by the removal of darkness; enlightened by the diffusion of light; and perfected by being brought to the perception of the colored object.

Reply Obj. 2: One angel can induce another to love God by persuasion as explained above.

Reply Obj. 3: The Philosopher speaks of the lower sensitive appetite which can be moved by the superior intellectual appetite, because it belongs to the same nature of the soul, and because the inferior appetite is a power in a corporeal organ. But this does not apply to the angels.

Whether an Inferior Angel Can Enlighten a Superior Angel?

Objection 1: It would seem that an inferior angel can enlighten a superior angel. For the ecclesiastical hierarchy is derived from, and represents the heavenly hierarchy; and hence the heavenly Jerusalem is called "our mother" (Gal. 4:26). But in the Church even superiors are enlightened and taught by their inferiors, as the Apostle says (1 Cor.

14:31): "You may all prophesy one by one, that all may learn and all may be exhorted." Therefore, likewise in the heavenly hierarchy, the superiors can be enlightened by inferiors.

Obj. 2: Further, as the order of corporeal substances depends on the will of God, so also does the order of spiritual substances. But, as was said above (Q. 105, A. 6), God sometimes acts outside the order of corporeal substances. Therefore He also sometimes acts outside the order of spiritual substances, by enlightening inferior otherwise than through their superiors. Therefore in that way the inferiors enlightened by God can enlighten superiors.

Obj. 3: Further, one angel enlightens the other to whom he turns, as was above explained (A. 1). But since this turning to another is voluntary, the highest angel can turn to the lowest passing over the others. Therefore he can enlighten him immediately; and thus the latter can enlighten his superiors.

_On the contrary,_ Dionysius says that "this is the Divine unalterable law, that inferior things are led to God by the superior" (Coel. Hier. iv; Eccl. Hier. v).

_I answer that,_ The inferior angels never enlighten the superior, but are always enlightened by them. The reason is, because, as above explained (Q. 105, A. 6), one order is under another, as cause is under cause; and hence as cause is ordered to cause, so is order to order. Therefore there is no incongruity if sometimes anything is done outside the order of the inferior cause, to be ordered to the superior cause, as in human affairs the command of the president is passed over from obedience to the prince. So it happens that God works miraculously outside the order of corporeal nature, that men may be ordered to the knowledge of Him. But the passing over of the order that belongs to spiritual substances in no way belongs to the ordering of men to God; since the angelic operations are not made known to us; as are the operations of sensible bodies. Thus the order which belongs to spiritual substances is never passed over by God; so that the inferiors are always moved by the superior, and not conversely.

Reply Obj. 1: The ecclesiastical hierarchy imitates the heavenly in some degree, but not by a perfect likeness. For in the heavenly hierarchy the perfection of the order is in proportion to its nearness to God; so that those who are the nearer to God are the more sublime in grade, and more clear in knowledge; and on that account the superiors are never enlightened by the inferiors, whereas in the ecclesiastical hierarchy, sometimes those who are the nearer to God in sanctity, are in the lowest grade, and are not conspicuous for science; and some also are eminent in one kind of science, and fail in another; and on that account superiors may be taught by inferiors.

Reply Obj. 2: As above explained, there is no similarity between what God does outside the order of corporeal nature, and that of spiritual nature. Hence the argument does not hold.

Reply Obj. 3: An angel turns voluntarily to enlighten another angel, but the angel's will is ever regulated by the Divine law which made the order in the angels.

Whether the Superior Angel Enlightens the Inferior As Regards All He Himself Knows?

Objection 1: It would seem that the superior angel does not enlighten the inferior concerning all he himself knows. For Dionysius says (Coel. Hier. xii) that the superior angels have a more universal knowledge; and the inferior a more particular and individual knowledge. But more is contained under a universal knowledge than under a particular knowledge. Therefore not all that the superior angels know, is known by the inferior, through these being enlightened by the former.

Obj. 2: Further, the Master of the Sentences (ii, D, 11) says that the superior angels had long known the Mystery of the Incarnation, whereas the inferior angels did not know it until it was accomplished. Thus we find that on some of the angels inquiring, as it were, in ignorance: "Who is this King of glory?" other angels, who knew, answered: "The Lord of Hosts, He is the King of glory," as Dionysius expounds (Coel. Hier. vii). But this would not apply if the superior angels enlightened the inferior concerning all they know themselves. Therefore they do not do so.

Obj. 3: Further, if the superior angels enlighten the inferior about all they know, nothing that the superior angels know would be unknown to the inferior angels. Therefore the superior angels could communicate nothing more to the inferior; which appears open to objection. Therefore the superior angels enlighten the inferior in all things.

_On the contrary,_ Gregory [*Peter Lombard, Sent. ii, D, ix; Cf.

Gregory, Hom. xxxiv, in Ev.] says: "In that heavenly country, though there are some excellent gifts, yet nothing is held individually."

And Dionysius says: "Each heavenly essence communicates to the inferior the gift derived from the superior" (Coel. Hier. xv), as quoted above (A. 1).

_I answer that,_ Every creature participates in the Divine goodness, so as to diffuse the good it possesses to others; for it is of the nature of good to communicate itself to others. Hence also corporeal agents give their likeness to others so far as they can. So the more an agent is established in the share of the Divine goodness, so much the more does it strive to transmit its perfections to others as far as possible. Hence the Blessed Peter admonishes those who by grace share in the Divine goodness; saying: "As every man hath received grace, ministering the same one to another; as good stewards of the manifold grace of God" (1 Pet. 4:10). Much more therefore do the holy angels, who enjoy the plenitude of participation of the Divine goodness, impart the same to those below them.

Nevertheless this gift is not received so excellently by the inferior as by the superior angels; and therefore the superior ever remain in a higher order, and have a more perfect knowledge; as the master understands the same thing better than the pupil who learns from him.

Reply Obj. 1: The knowledge of the superior angels is said to be more universal as regards the more eminent mode of knowledge.

Reply Obj. 2: The Master's words are not to be understood as if the inferior angels were entirely ignorant of the Mystery of the Incarnation but that they did not know it as fully as the superior angels; and that they progressed in the knowledge of it afterwards when the Mystery was accomplished.

Reply Obj. 3: Till the Judgment Day some new things are always being revealed by God to the highest angels, concerning the course of the world, and especially the salvation of the elect. Hence there is always something for the superior angels to make known to the inferior.

QUESTION 107 THE SPEECH OF THE ANGELS (In Five Articles) We next consider the speech of the angels. Here there are five points of inquiry: (1) Whether one angel speaks to another?

(2) Whether the inferior speaks to the superior?

(3) Whether an angel speaks to God?

(4) Whether the angelic speech is subject to local distance?

(5) Whether all the speech of one angel to another is known to all?

Whether One Angel Speaks to Another?

Objection 1: It would seem that one angel does not speak to another.

For Gregory says (Moral. xviii) that, in the state of the resurrection "each one's body will not hide his mind from his fellows." Much less, therefore, is one angel's mind hidden from another. But speech manifests to another what lies hidden in the mind. Therefore it is not necessary that one angel should speak to another.

Obj. 2: Further, speech is twofold; interior, whereby one speaks to oneself; and exterior, whereby one speaks to another. But exterior speech takes place by some sensible sign, as by voice, or gesture, or some bodily member, as the tongue, or the fingers, and this cannot apply to the angels. Therefore one angel does not speak to another.

Obj. 3: Further, the speaker incites the hearer to listen to what he says. But it does not appear that one angel incites another to listen; for this happens among us by some sensible sign. Therefore one angel does not speak to another.

_On the contrary,_ The Apostle says (1 Cor. 13:1): "If I speak with the tongues of men and of angels."

_I answer that,_ The angels speak in a certain way. But, as Gregory says (Moral. ii): "It is fitting that our mind, rising above the properties of bodily speech, should be lifted to the sublime and unknown methods of interior speech."

To understand how one angel speaks to another, we must consider that, as we explained above (Q. 82, A. 4), when treating of the actions and powers of the soul, the will moves the intellect to its operation.

Now an intelligible object is present to the intellect in three ways; first, habitually, or in the memory, as Augustine says (De Trin. xiv, 6, 7); secondly, as actually considered or conceived; thirdly, as related to something else. And it is clear that the intelligible object passes from the first to the second stage by the command of the will, and hence in the definition of habit these words occur, "which anyone uses when he wills." So likewise the intelligible object passes from the second to the third stage by the will; for by the will the concept of the mind is ordered to something else, as, for instance, either to the performing of an action, or to being made known to another. Now when the mind turns itself to the actual consideration of any habitual knowledge, then a person speaks to himself; for the concept of the mind is called "the interior word."

And by the fact that the concept of the angelic mind is ordered to be made known to another by the will of the angel himself, the concept of one angel is made known to another; and in this way one angel speaks to another; for to speak to another only means to make known the mental concept to another.

Reply Obj. 1: Our mental concept is hidden by a twofold obstacle. The first is in the will, which can retain the mental concept within, or can direct it externally. In this way God alone can see the mind of another, according to 1 Cor. 2:11: "What man knoweth the things of a man, but the spirit of a man that is in him?" The other obstacle whereby the mental concept is excluded from another one's knowledge, comes from the body; and so it happens that even when the will directs the concept of the mind to make itself known, it is not at once make known to another; but some sensible sign must be used.

Gregory alludes to this fact when he says (Moral. ii): "To other eyes we seem to stand aloof as it were behind the wall of the body; and when we wish to make ourselves known, we go out as it were by the door of the tongue to show what we really are." But an angel is under no such obstacle, and so he can make his concept known to another at once.

Reply Obj. 2: External speech, made by the voice, is a necessity for us on account of the obstacle of the body. Hence it does not befit an angel; but only interior speech belongs to him, and this includes not only the interior speech by mental concept, but also its being ordered to another's knowledge by the will. So the tongue of an angel is called metaphorically the angel's power, whereby he manifests his mental concept.

Reply Obj. 3: There is no need to draw the attention of the good angels, inasmuch as they always see each other in the Word; for as one ever sees the other, so he ever sees what is ordered to himself.

But because by their very nature they can speak to each other, and even now the bad angels speak to each other, we must say that the intellect is moved by the intelligible object just as sense is affected by the sensible object. Therefore, as sense is aroused by the sensible object, so the mind of an angel can be aroused to attention by some intelligible power.

Whether the Inferior Angel Speaks to the Superior?

Objection 1: It would seem that the inferior angel does not speak to the superior. For on the text (1 Cor. 13:1), "If I speak with the tongues of men and of angels," a gloss remarks that the speech of the angels is an enlightenment whereby the superior enlightens the inferior. But the inferior never enlightens the superior, as was above explained (Q. 106, A. 3). Therefore neither do the inferior speak to the superior.

Obj. 2: Further, as was said above (Q. 106, A. 1), to enlighten means merely to acquaint one man of what is known to another; and this is to speak. Therefore to speak and to enlighten are the same; so the same conclusion follows.

Obj. 3: Further, Gregory says (Moral. ii): "God speaks to the angels by the very fact that He shows to their hearts His hidden and invisible things." But this is to enlighten them. Therefore, whenever God speaks, He enlightens. In the same way every angelic speech is an enlightening. Therefore an inferior angel can in no way speak to a superior angel.

_On the contrary,_ According to the exposition of Dionysius (Coel.

Hier. vii), the inferior angels said to the superior: "Who is this King of Glory?"

_I answer that,_ The inferior angels can speak to the superior. To make this clear, we must consider that every angelic enlightening is an angelic speech; but on the other hand, not every speech is an enlightening; because, as we have said (A. 1), for one angel to speak to another angel means nothing else, but that by his own will he directs his mental concept in such a way, that it becomes known to the other. Now what the mind conceives may be reduced to a twofold principle; to God Himself, Who is the primal truth; and to the will of the one who understands, whereby we actually consider anything.

But because truth is the light of the intellect, and God Himself is the rule of all truth; the manifestation of what is conceived by the mind, as depending on the primary truth, is both speech and enlightenment; for example, when one man says to another: "Heaven was created by God"; or, "Man is an animal." The manifestation, however, of what depends on the will of the one who understands, cannot be called an enlightenment, but is only a speech; for instance, when one says to another: "I wish to learn this; I wish to do this or that."

The reason is that the created will is not a light, nor a rule of truth; but participates of light. Hence to communicate what comes from the created will is not, as such, an enlightening. For to know what you may will, or what you may understand does not belong to the perfection of my intellect; but only to know the truth in reality.

Now it is clear that the angels are called superior or inferior by comparison with this principle, God; and therefore enlightenment, which depends on the principle which is God, is conveyed only by the superior angels to the inferior. But as regards the will as the principle, he who wills is first and supreme; and therefore the manifestation of what belongs to the will, is conveyed to others by the one who wills. In that manner both the superior angels speak to the inferior, and the inferior speak to the superior.

From this clearly appear the replies to the first and second objections.

Reply Obj. 3: Every speech of God to the angels is an enlightening; because since the will of God is the rule of truth, it belongs to the perfection and enlightenment of the created mind to know even what God wills. But the same does not apply to the will of the angels, as was explained above.

Whether an Angel Speaks to God?

Objection 1: It would seem that an angel does not speak to God. For speech makes known something to another. But an angel cannot make known anything to God, Who knows all things. Therefore an angel does not speak to God.

Obj. 2: Further, to speak is to order the mental concept in reference to another, as was shown above (A. 1). But an angel ever orders his mental concept to God. So if an angel speaks to God, he ever speaks to God; which in some ways appears to be unreasonable, since an angel sometimes speaks to another angel. Therefore it seems that an angel never speaks to God.

_On the contrary,_ It is written (Zech. 1:12): "The angel of the Lord answered and said: O Lord of hosts, how long wilt Thou not have mercy on Jerusalem." Therefore an angel speaks to God.

_I answer that,_ As was said above (AA. 1, 2), the angel speaks by ordering his mental concept to something else. Now one thing is ordered to another in a twofold manner. In one way for the purpose of giving one thing to another, as in natural things the agent is ordered to the patient, and in human speech the teacher is ordered to the learner; and in this sense an angel in no way speaks to God either of what concerns the truth, or of whatever depends on the created will; because God is the principle and source of all truth and of all will. In another way one thing is ordered to another to receive something, as in natural things the passive is ordered to the agent, and in human speech the disciple to the master; and in this way an angel speaks to God, either by consulting the Divine will of what ought to be done, or by admiring the Divine excellence which he can never comprehend; thus Gregory says (Moral. ii) that "the angels speak to God, when by contemplating what is above themselves they rise to emotions of admiration."

Reply Obj. 1: Speech is not always for the purpose of making something known to another; but is sometimes finally ordered to the purpose of manifesting something to the speaker himself; as when the disciples ask instruction from the master.

Reply Obj. 2: The angels are ever speaking to God in the sense of praising and admiring Him and His works; but they speak to Him by consulting Him about what ought to be done whenever they have to perform any new work, concerning which they desire enlightenment.

Whether Local Distance Influences the Angelic Speech?

Objection 1: It would seem that local distance affects the angelic speech. For as Damascene says (De Fide Orth. i, 13): "An angel works where he is." But speech is an angelic operation. Therefore, as an angel is in a determinate place, it seems that an angel's speech is limited by the bounds of that place.

Obj. 2: Further, a speaker cries out on account of the distance of the hearer. But it is said of the Seraphim that "they cried one to another" (Isa. 6:3). Therefore in the angelic speech local distance has some effect.

_On the contrary,_ It is said that the rich man in hell spoke to Abraham, notwithstanding the local distance (Luke 16:24). Much less therefore does local distance impede the speech of one angel to another.

_I answer that,_ The angelic speech consists in an intellectual operation, as explained above (AA. 1, 2, 3). And the intellectual operation of an angel abstracts from the "here and now." For even our own intellectual operation takes place by abstraction from the "here and now," except accidentally on the part of the phantasms, which do not exist at all in an angel. But as regards whatever is abstracted from "here and now," neither difference of time nor local distance has any influence whatever. Hence in the angelic speech local distance is no impediment.

Reply Obj. 1: The angelic speech, as above explained (A. 1, ad 2), is interior; perceived, nevertheless, by another; and therefore it exists in the angel who speaks, and consequently where the angel is who speaks. But as local distance does not prevent one angel seeing another, so neither does it prevent an angel perceiving what is ordered to him on the part of another; and this is to perceive his speech.

Reply Obj. 2: The cry mentioned is not a bodily voice raised by reason of the local distance; but is taken to signify the magnitude of what is said, or the intensity of the affection, according to what Gregory says (Moral. ii): "The less one desires, the less one cries out."

Whether All the Angels Know What One Speaks to Another?

Objection 1: It would seem that all the angels know what one speaks to another. For unequal local distance is the reason why all men do not know what one man says to another. But in the angelic speech local distance has no effect, as above explained (A. 4). Therefore all the angels know what one speaks to another.

Obj. 2: Further, all the angels have the intellectual power in common. So if the mental concept of one ordered to another is known by one, it is for the same reason known by all.

Obj. 3: Further, enlightenment is a kind of speech. But the enlightenment of one angel by another extends to all the angels, because, as Dionysius says (Coel. Hier. xv): "Each one of the heavenly beings communicates what he learns to the others." Therefore the speech of one angel to another extends to all.

_On the contrary,_ One man can speak to another alone; much more can this be the case among the angels.

_I answer that,_ As above explained (AA. 1, 2), the mental concept of one angel can be perceived by another when the angel who possesses the concept refers it by his will to another. Now a thing can be ordered through some cause to one thing and not to another; consequently the concept of one (angel) may be known by one and not by another; and therefore an angel can perceive the speech of one angel to another; whereas others do not, not through the obstacle of local distance, but on account of the will so ordering, as explained above.

From this appear the replies to the first and second objections.

Reply Obj. 3: Enlightenment is of those truths that emanate from the first rule of truth, which is the principle common to all the angels; and in that way all enlightenments are common to all. But speech may be of something ordered to the principle of the created will, which is proper to each angel; and in this way it is not necessary that these speeches should be common to all.

QUESTION 108 OF THE ANGELIC DEGREES OF HIERARCHIES AND ORDERS (In Eight Articles) We next consider the degrees of the angels in their hierarchies and orders; for it was said above (Q. 106, A. 3), that the superior angels enlighten the inferior angels; and not conversely.

Under this head there are eight points of inquiry: (1) Whether all the angels belong to one hierarchy?

(2) Whether in one hierarchy there is only one order?

(3) Whether in one order there are many angels?

(4) Whether the distinction of hierarchies and orders is natural?

(5) Of the names and properties of each order.

(6) Of the comparison of the orders to one another.

(7) Whether the orders will outlast the Day of Judgment?

(8) Whether men are taken up into the angelic orders?

Whether All the Angels Are of One Hierarchy?

Objection 1: It would seem that all the angels belong to one hierarchy. For since the angels are supreme among creatures, it is evident that they are ordered for the best. But the best ordering of a multitude is for it to be governed by one authority, as the Philosopher shows (Metaph. xii, Did. xi, 10; Polit. iii, 4).

Therefore as a hierarchy is nothing but a sacred principality, it seems that all the angels belong to one hierarchy.

Obj. 2: Further, Dionysius says (Coel. Hier. iii) that "hierarchy is order, knowledge, and action." But all the angels agree in one order towards God, Whom they know, and by Whom in their actions they are ruled. Therefore all the angels belong to one hierarchy.

Obj. 3: Further, the sacred principality called hierarchy is to be found among men and angels. But all men are of one hierarchy.

Therefore likewise all the angels are of one hierarchy.

_On the contrary,_ Dionysius (Coel. Hier. vi) distinguishes three hierarchies of angels.

_I answer that,_ Hierarchy means a "sacred" principality, as above explained. Now principality includes two things: the prince himself and the multitude ordered under the prince. Therefore because there is one God, the Prince not only of all the angels but also of men and all creatures; so there is one hierarchy, not only of all the angels, but also of all rational creatures, who can be participators of sacred things; according to Augustine (De Civ. Dei xii, 1): "There are two cities, that is, two societies, one of the good angels and men, the other of the wicked." But if we consider the principality on the part of the multitude ordered under the prince, then principality is said to be "one" accordingly as the multitude can be subject in _one_ way to the government of the prince. And those that cannot be governed in the same way by a prince belong to different principalities: thus, under one king there are different cities, which are governed by different laws and administrators. Now it is evident that men do not receive the Divine enlightenments in the same way as do the angels; for the angels receive them in their intelligible purity, whereas men receive them under sensible signs, as Dionysius says (Coel. Hier. i). Therefore there must needs be a distinction between the human and the angelic hierarchy. In the same manner we distinguish three angelic hierarchies. For it was shown above (Q. 55, A. 3), in treating of the angelic knowledge, that the superior angels have a more universal knowledge of the truth than the inferior angels. This universal knowledge has three grades among the angels. For the types of things, concerning which the angels are enlightened, can be considered in a threefold manner. First as preceding from God as the first universal principle, which mode of knowledge belongs to the first hierarchy, connected immediately with God, and, "as it were, placed in the vestibule of God," as Dionysius says (Coel. Hier. vii). Secondly, forasmuch as these types depend on the universal created causes which in some way are already multiplied; which mode belongs to the second hierarchy. Thirdly, forasmuch as these types are applied to particular things as depending on their causes; which mode belongs to the lowest hierarchy. All this will appear more clearly when we treat of each of the orders (A. 6). In this way are the hierarchies distinguished on the part of the multitude of subjects.

Hence it is clear that those err and speak against the opinion of Dionysius who place a hierarchy in the Divine Persons, and call it the "supercelestial" hierarchy. For in the Divine Persons there exists, indeed, a natural order, but there is no hierarchical order, for as Dionysius says (Coel. Hier. iii): "The hierarchical order is so directed that some be cleansed, enlightened, and perfected; and that others cleanse, enlighten, and perfect"; which far be it from us to apply to the Divine Persons.

Reply Obj. 1: This objection considers principality on the part of the ruler, inasmuch as a multitude is best ruled by one ruler, as the Philosopher asserts in those passages.

Reply Obj. 2: As regards knowing God Himself, Whom all see in one way--that is, in His essence--there is no hierarchical distinction among the angels; but there is such a distinction as regards the types of created things, as above explained.

Reply Obj. 3: All men are of one species, and have one connatural mode of understanding; which is not the case in the angels: and hence the same argument does not apply to both.

Whether There Are Several Orders in One Hierarchy?

Objection 1: It would seem that in the one hierarchy there are not several orders. For when a definition is multiplied, the thing defined is also multiplied. But hierarchy is order, as Dionysius says (Coel.

Hier. iii). Therefore, if there are many orders, there is not one hierarchy only, but many.

Obj. 2: Further, different orders are different grades, and grades among spirits are constituted by different spiritual gifts. But among the angels all the spiritual gifts are common to all, for "nothing is possessed individually" (Sent. ii, D, ix). Therefore there are not different orders of angels.

Obj. 3: Further, in the ecclesiastical hierarchy the orders are distinguished according to the actions of "cleansing," "enlightening," and "perfecting." For the order of deacons is "cleansing," the order of priests, is "enlightening," and of bishops "perfecting," as Dionysius says (Eccl. Hier. v). But each of the angels cleanses, enlightens, and perfects. Therefore there is no distinction of orders among the angels.

_On the contrary,_ The Apostle says (Eph. 1:20,21) that "God has set the Man Christ above all principality and power, and virtue, and dominion": which are the various orders of the angels, and some of them belong to one hierarchy, as will be explained (A. 6).

_I answer that,_ As explained above, one hierarchy is one principality--that is, one multitude ordered in one way under the rule of a prince. Now such a multitude would not be ordered, but confused, if there were not in it different orders. So the nature of a hierarchy requires diversity of orders.

This diversity of order arises from the diversity of offices and actions, as appears in one city where there are different orders according to the different actions; for there is one order of those who judge, and another of those who fight, and another of those who labor in the fields, and so forth.

But although one city thus comprises several orders, all may be reduced to three, when we consider that every multitude has a beginning, a middle, and an end. So in every city, a threefold order of men is to be seen, some of whom are supreme, as the nobles; others are the last, as the common people, while others hold a place between these, as the middle-class [populus honorabilis]. In the same way we find in each angelic hierarchy the orders distinguished according to their actions and offices, and all this diversity is reduced to three--namely, to the summit, the middle, and the base; and so in every hierarchy Dionysius places three orders (Coel. Hier. vi).
