FIRST ARTICLE [I, Q. 111, Art. 1]

Whether an Angel Can Enlighten Man?

Objection 1: It would seem that an angel cannot enlighten man. For

man is enlightened by faith; hence Dionysius (Eccl. Hier. iii)

attributes enlightenment to baptism, as "the sacrament of faith." But

faith is immediately from God, according to Eph. 2:8: "By grace you

are saved through faith, and that not of yourselves, for it is the

gift of God." Therefore man is not enlightened by an angel; but

immediately by God.

Obj. 2: Further, on the words, "God hath manifested it to them" (Rom.

1:19), the gloss observes that "not only natural reason availed for

the manifestation of Divine truths to men, but God also revealed them

by His work," that is, by His creature. But both are immediately from

God--that is, natural reason and the creature. Therefore God

enlightens man immediately.

Obj. 3: Further, whoever is enlightened is conscious of being

enlightened. But man is not conscious of being enlightened by angels.

Therefore he is not enlightened by them.

_On the contrary,_ Dionysius says (Coel. Hier. iv) that the

revelation of Divine things reaches men through the ministry of the

angels. But such revelation is an enlightenment as we have stated

(Q. 106, A. 1; Q. 107, A. 2). Therefore men are enlightened by the

angels.

_I answer that,_ Since the order of Divine Providence disposes that

lower things be subject to the actions of higher, as explained above

(Q. 109, A. 2); as the inferior angels are enlightened by the

superior, so men, who are inferior to the angels, are enlightened by

them.

The modes of each of these kinds of enlightenment are in one way

alike and in another way unlike. For, as was shown above (Q. 106, A.

1), the enlightenment which consists in making known Divine truth has

two functions; namely, according as the inferior intellect is

strengthened by the action of the superior intellect, and according

as the intelligible species which are in the superior intellect are

proposed to the inferior so as to be grasped thereby. This takes

place in the angels when the superior angel divides his universal

concept of the truth according to the capacity of the inferior angel,

as explained above (Q. 106, A. 1).

The human intellect, however, cannot grasp the universal truth itself

unveiled; because its nature requires it to understand by turning to

the phantasms, as above explained (Q. 84, A. 7). So the angels

propose the intelligible truth to men under the similitudes of

sensible things, according to what Dionysius says (Coel. Hier. i),

that, "It is impossible for the divine ray to shine on us, otherwise

than shrouded by the variety of the sacred veils." On the other hand,

the human intellect as the inferior, is strengthened by the action of

the angelic intellect. And in these two ways man is enlightened by an

angel.

Reply Obj. 1: Two dispositions concur in the virtue of faith; first,

the habit of the intellect whereby it is disposed to obey the will

tending to Divine truth. For the intellect assents to the truth of

faith, not as convinced by the reason, but as commanded by the will;

hence Augustine says, "No one believes except willingly." In this

respect faith comes from God alone. Secondly, faith requires that

what is to be believed be proposed to the believer; which is

accomplished by man, according to Rom. 10:17, "Faith cometh by

hearing"; principally, however, by the angels, by whom Divine things

are revealed to men. Hence the angels have some part in the

enlightenment of faith. Moreover, men are enlightened by the angels

not only concerning what is to be believed; but also as regards what

is to be done.

Reply Obj. 2: Natural reason, which is immediately from God, can be

strengthened by an angel, as we have said above. Again, the more the

human intellect is strengthened, so much higher an intelligible truth

can be elicited from the species derived from creatures. Thus man is

assisted by an angel so that he may obtain from creatures a more

perfect knowledge of God.

Reply Obj. 3: Intellectual operation and enlightenment can be

understood in two ways. First, on the part of the object understood;

thus whoever understands or is enlightened, knows that he understands

or is enlightened, because he knows that the object is made known to

him. Secondly, on the part of the principle; and thus it does not

follow that whoever understands a truth, knows what the intellect is,

which is the principle of the intellectual operation. In like manner

not everyone who is enlightened by an angel, knows that he is

enlightened by him.
