FIRST ARTICLE [I, Q. 106, Art. 1]

Whether One Angel Enlightens Another?

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

For the angels possess now the same beatitude which we hope to obtain.

But one man will not then enlighten another, according to Jer. 31:34:

"They shall teach no more every man his neighbor, and every man his

brother." Therefore neither does an angel enlighten another now.

Obj. 2: Further, light in the angels is threefold; of nature, of

grace, and of glory. But an angel is enlightened in the light of

nature by the Creator; in the light of grace by the Justifier; in

the light of glory by the Beatifier; all of which comes from God.

Therefore one angel does not enlighten another.

Obj. 3: Further, light is a form in the mind. But the rational

mind is "informed by God alone, without created intervention," as

Augustine says (QQ. 83, qu. 51). Therefore one angel does not

enlighten the mind of another.

_On the contrary,_ Dionysius says (Coel. Hier. viii) that "the angels

of the second hierarchy are cleansed, enlightened and perfected by

the angels of the first hierarchy."

_I answer that,_ One angel enlightens another. To make this clear,

we must observe that intellectual light is nothing else than a

manifestation of truth, according to Eph. 5:13: "All that is made

manifest is light." Hence to enlighten means nothing else but to

communicate to others the manifestation of the known truth; according

to the Apostle (Eph. 3:8): "To me the least of all the saints is

given this grace . . . to enlighten all men, that they may see what

is the dispensation of the mystery which hath been hidden from

eternity in God." Therefore one angel is said to enlighten another by

manifesting the truth which he knows himself. Hence Dionysius says

(Coel. Hier. vii): "Theologians plainly show that the orders of the

heavenly beings are taught Divine science by the higher minds."

Now since two things concur in the intellectual operation, as we

have said (Q. 105, A. 3), namely, the intellectual power, and the

likeness of the thing understood; in both of these one angel can

notify the known truth to another. First, by strengthening his

intellectual power; for just as the power of an imperfect body is

strengthened by the neighborhood of a more perfect body--for

instance, the less hot is made hotter by the presence of what is

hotter; so the intellectual power of an inferior angel is strengthened

by the superior angel turning to him: since in spiritual things, for

one thing to turn to another, corresponds to neighborhood in corporeal

things. Secondly, one angel manifests the truth to another as regards

the likeness of the thing understood. For the superior angel receives

the knowledge of truth by a kind of universal conception, to receive

which the inferior angel's intellect is not sufficiently powerful, for

it is natural to him to receive truth in a more particular manner.

Therefore the superior angel distinguishes, in a way, the truth which

he conceives universally, so that it can be grasped by the inferior

angel; and thus he proposes it to his knowledge. Thus it is with us

that the teacher, in order to adapt himself to others, divides into

many points the knowledge which he possesses in the universal. This

is thus expressed by Dionysius (Coel. Hier. xv): "Every intellectual

substance with provident power divides and multiplies the uniform

knowledge bestowed on it by one nearer to God, so as to lead its

inferiors upwards by analogy."

Reply Obj. 1: All the angels, both inferior and superior, see the

Essence of God immediately, and in this respect one does not teach

another. It is of this truth that the prophet speaks; wherefore he

adds: "They shall teach no more every man his brother, saying: 'Know

the Lord': for all shall know Me, from the least of them even to the

greatest." But all the types of the Divine works, which are known in

God as in their cause, God knows in Himself, because He comprehends

Himself; but of others who see God, each one knows the more types,

the more perfectly he sees God. Hence a superior angel knows more

about the types of the Divine works than an inferior angel, and

concerning these the former enlightens the latter; and as to this

Dionysius says (Div. Nom. iv) that the angels "are enlightened by

the types of existing things."

Reply Obj. 2: An angel does not enlighten another by giving him the

light of nature, grace, or glory; but by strengthening his natural

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.
