SECOND ARTICLE [I, Q. 108, Art. 2]

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).

Reply Obj. 1: Order is twofold. In one way it is taken as the order

comprehending in itself different grades; and in that way a hierarchy

is called an order. In another way one grade is called an order; and

in that sense the several orders of one hierarchy are so called.

Reply Obj. 2: All things are possessed in common by the angelic

society, some things, however, being held more excellently by some

than by others. Each gift is more perfectly possessed by the one who

can communicate it, than by the one who cannot communicate it; as the

hot thing which can communicate heat is more perfect that what is

unable to give heat. And the more perfectly anyone can communicate a

gift, the higher grade he occupies, as he is in the more perfect

grade of mastership who can teach a higher science. By this

similitude we can reckon the diversity of grades or orders among the

angels, according to their different offices and actions.

Reply Obj. 3: The inferior angel is superior to the highest man of

our hierarchy, according to the words, "He that is the lesser in the

kingdom of heaven, is greater than he"--namely, John the Baptist,

than whom "there hath not risen a greater among them that are born of

women" (Matt. 11:11). Hence the lesser angel of the heavenly

hierarchy can not only cleanse, but also enlighten and perfect, and

in a higher way than can the orders of our hierarchy. Thus the

heavenly orders are not distinguished by reason of these, but by

reason of other different acts.
