FIRST ARTICLE [I, Q. 108, Art. 1]

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.
