Summa Theologica Part III (Secunda Secundae) Part 246

Reply Obj. 1: As stated in the First Part (Q. 14, A. 13) the cert.i.tude of the Divine foreknowledge does not exclude the contingency of future singular events, because that knowledge regards the future as present and already determinate to one thing. Wherefore prophecy also, which is an "impressed likeness" or "seal of the Divine foreknowledge," does not by its unchangeable truth exclude the contingency of future things.

Reply Obj. 2: The Divine foreknowledge regards future things in two ways. First, as they are in themselves, in so far, to wit, as it sees them in their presentiality: secondly, as in their causes, inasmuch as it sees the order of causes in relation to their effects. And though future contingencies, considered as in themselves, are determinate to one thing, yet, considered as in their causes, they are not so determined but that they can happen otherwise. Again, though this twofold knowledge is always united in the Divine intellect, it is not always united in the prophetic revelation, because an imprint made by an active cause is not always on a par with the virtue of that cause. Hence sometimes the prophetic revelation is an imprinted likeness of the Divine foreknowledge, in so far as the latter regards future contingencies in themselves: and such things happen in the same way as foretold, for example this saying of Isa. 7:14: "Behold a virgin shall conceive." Sometimes, however, the prophetic revelation is an imprinted likeness of the Divine foreknowledge as knowing the order of causes to effects; and then at times the event is otherwise than foretold. Yet the prophecy does not cover a falsehood, for the meaning of the prophecy is that inferior causes, whether they be natural causes or human acts, are so disposed as to lead to such a result. In this way we are to understand the saying of Isa. 38:1: "Thou shalt die, and not live"; in other words, "The disposition of thy body has a tendency to death": and the saying of Jonah 3:4, "Yet forty days, and Nineveh shall be destroyed," that is to say, "Its merits demand that it should be destroyed." G.o.d is said "to repent," metaphorically, inasmuch as He bears Himself after the manner of one who repents, by "changing His sentence, although He changes not His counsel" [*Cf. I, Q. 19, A. 7, ad 2].

Reply Obj. 3: Since the same truth of prophecy is the same as the truth of Divine foreknowledge, as stated above, the conditional proposition: "If this was prophesied, it will be," is true in the same way as the proposition: "If this was foreknown, it will be": for in both cases it is impossible for the antecedent not to be. Hence the consequent is necessary, considered, not as something future in our regard, but as being present to the Divine foreknowledge, as stated in the First Part (Q. 14, A. 13, ad 2).

QUESTION 172

OF THE CAUSE OF PROPHECY (In Six Articles)

We must now consider the cause of prophecy. Under this head there are six points of inquiry:

(1) Whether prophecy is natural?

(2) Whether it is from G.o.d by means of the angels?

(3) Whether a natural disposition is requisite for prophecy?

(4) Whether a good life is requisite?

(5) Whether any prophecy is from the demons?

(6) Whether prophets of the demons ever tell what is true?

FIRST ARTICLE [II-II, Q. 172, Art. 1]

Whether Prophecy Can Be Natural?

Objection 1: It would seem that prophecy can be natural. For Gregory says (Dial. iv, 26) that "sometimes the mere strength of the soul is sufficiently cunning to foresee certain things": and Augustine says (Gen. ad lit. xii, 13) that the human soul, according as it is withdrawn from the sense of the body, is able to foresee the future [*Cf. I, Q. 86, A. 4, ad 2]. Now this pertains to prophecy. Therefore the soul can acquire prophecy naturally.

Obj. 2: Further, the human soul's knowledge is more alert while one wakes than while one sleeps. Now some, during sleep, naturally foresee the future, as the Philosopher a.s.serts (De Somn. et Vigil.

[*De Divinat. per Somn. ii, which is annexed to the work quoted]).

Much more therefore can a man naturally foreknow the future.

Obj. 3: Further, man, by his nature, is more perfect than dumb animals. Yet some dumb animals have foreknowledge of future things that concern them. Thus ants foreknow the coming rains, which is evident from their gathering grain into their nest before the rain commences; and in like manner fish foreknow a coming storm, as may be gathered from their movements in avoiding places exposed to storm.

Much more therefore can men foreknow the future that concerns themselves, and of such things is prophecy. Therefore prophecy comes from nature.

Obj. 4: Further, it is written (Prov. 29:18): "When prophecy shall fail, the people shall be scattered abroad"; wherefore it is evident that prophecy is necessary for the stability of the human race. Now "nature does not fail in necessaries" [*Aristotle, _De Anima_ iii, 9]. Therefore it seems that prophecy is from nature.

_On the contrary,_ It is written (2 Pet. 1:21): "For prophecy came not by the will of man at any time, but the holy men of G.o.d spoke, inspired by the Holy Ghost." Therefore prophecy comes not from nature, but through the gift of the Holy Ghost.

_I answer that,_ As stated above (Q. 171, A. 6, ad 2) prophetic foreknowledge may regard future things in two ways: in one way, as they are in themselves; in another way, as they are in their causes.

Now, to foreknow future things, as they are in themselves, is proper to the Divine intellect, to Whose eternity all things are present, as stated in the First Part (Q. 14, A. 13). Wherefore such like foreknowledge of the future cannot come from nature, but from Divine revelation alone. On the other hand, future things can be foreknown in their causes with a natural knowledge even by man: thus a physician foreknows future health or death in certain causes, through previous experimental knowledge of the order of those causes to such effects. Such like knowledge of the future may be understood to be in a man by nature in two ways. In one way that the soul, from that which it holds, is able to foreknow the future, and thus Augustine says (Gen. ad lit. xii, 13): "Some have deemed the human soul to contain a certain power of divination." This seems to be in accord with the opinion of Plato [*Phaed. xxvii; Civit. vi], who held that our souls have knowledge of all things by partic.i.p.ating in the ideas; but that this knowledge is obscured in them by union with the body; yet in some more, in others less, according to a difference in bodily purity. According to this it might be said that men, whose souls are not much obscured through union with the body, are able to foreknow such like future things by their own knowledge. Against this opinion Augustine says (Gen. ad lit. xii, 13): "How is it that the soul cannot always have this power of divination, since it always wishes to have it?"

Since, however, it seems truer, according to the opinion of Aristotle, that the soul acquires knowledge from sensibles, as stated in the First Part (Q. 84, A. 6), it is better to have recourse to another explanation, and to hold that men have no such foreknowledge of the future, but that they can acquire it by means of experience, wherein they are helped by their natural disposition, which depends on the perfection of a man's imaginative power, and the clarity of his understanding.

Nevertheless this latter foreknowledge of the future differs in two ways from the former, which comes through Divine revelation. First, because the former can be about any events whatever, and this infallibly; whereas the latter foreknowledge, which can be had naturally, is about certain effects, to which human experience may extend. Secondly, because the former prophecy is "according to the unchangeable truth" [*Q. 171, A. 3, Obj. 1], while the latter is not, and can cover a falsehood. Now the former foreknowledge, and not the latter, properly belongs to prophecy, because, as stated above (Q.

171, A. 3), prophetic knowledge is of things which naturally surpa.s.s human knowledge. Consequently we must say that prophecy strictly so called cannot be from nature, but only from Divine revelation.

Reply Obj. 1: When the soul is withdrawn from corporeal things, it becomes more adapted to receive the influence of spiritual substances [*Cf. I, Q. 88, A. 4, ad 2], and also is more inclined to receive the subtle motions which take place in the human imagination through the impression of natural causes, whereas it is hindered from receiving them while occupied with sensible things. Hence Gregory says (Dial.

iv, 26) that "the soul, at the approach of death, foresees certain future things, by reason of the subtlety of its nature," inasmuch as it is receptive even of slight impressions. Or again, it knows future things by a revelation of the angels; but not by its own power, because according to Augustine (Gen. ad lit. xii, 13), "if this were so, it would be able to foreknow the future whenever it willed,"

which is clearly false.

Obj. 2: Knowledge of the future by means of dreams, comes either from the revelation of spiritual substances, or from a corporeal cause, as stated above (Q. 95, A. 6), when we were treating of divination. Now both these causes are more applicable to a person while asleep than while awake, because, while awake, the soul is occupied with external sensibles, so that it is less receptive of the subtle impressions either of spiritual substances, or even of natural causes; although as regards the perfection of judgment, the reason is more alert in waking than in sleeping.

Reply Obj. 3: Even dumb animals have no foreknowledge of future events, except as these are foreknown in their causes, whereby their imagination is moved more than man's, because man's imagination, especially in waking, is more disposed according to reason than according to the impression of natural causes. Yet reason effects much more amply in man, that which the impression of natural causes effects in dumb animals; and Divine grace by inspiring the prophecy a.s.sists man still more.

Reply Obj. 4: The prophetic light extends even to the direction of human acts; and in this way prophecy is requisite for the government of a people, especially in relation to Divine worship; since for this nature is not sufficient, and grace is necessary.

SECOND ARTICLE [II-II, Q. 172, Art. 2]

Whether Prophetic Revelation Comes Through the Angels?

Objection 1: It would seem that prophetic revelation does not come through the angels. For it is written (Wis. 7:27) that Divine wisdom "conveyeth herself into holy souls," and "maketh the friends of G.o.d, and the prophets." Now wisdom makes the friends of G.o.d immediately.

Therefore it also makes the prophets immediately, and not through the medium of the angels.

Obj. 2: Further, prophecy is reckoned among the gratuitous graces.

But the gratuitous graces are from the Holy Ghost, according to 1 Cor. 12:4, "There are diversities of graces, but the same Spirit."

Therefore the prophetic revelation is not made by means of an angel.

Obj. 3: Further, Ca.s.siodorus [*Prol. in Psalt. i] says that prophecy is a "Divine revelation": whereas if it were conveyed by the angels, it would be called an angelic revelation. Therefore prophecy is not bestowed by means of the angels.

_On the contrary,_ Dionysius says (Coel. Hier. iv): "Our glorious fathers received Divine visions by means of the heavenly powers"; and he is speaking there of prophetic visions. Therefore prophetic revelation is conveyed by means of the angels.

_I answer that,_ As the Apostle says (Rom. 13:1), "Things that are of G.o.d are well ordered [*Vulg.: 'Those that are, are ordained of G.o.d.']." Now the Divine ordering, according to Dionysius [*Coel.

Hier. iv; Eccl. Hier. v], is such that the lowest things are directed by middle things. Now the angels hold a middle position between G.o.d and men, in that they have a greater share in the perfection of the Divine goodness than men have. Wherefore the Divine enlightenments and revelations are conveyed from G.o.d to men by the angels. Now prophetic knowledge is bestowed by Divine enlightenment and revelation. Therefore it is evident that it is conveyed by the angels.

Reply Obj. 1: Charity which makes man a friend of G.o.d, is a perfection of the will, in which G.o.d alone can form an impression; whereas prophecy is a perfection of the intellect, in which an angel also can form an impression, as stated in the First Part (Q. 111, A.

1), wherefore the comparison fails between the two.

Reply Obj. 2: The gratuitous graces are ascribed to the Holy Ghost as their first principle: yet He works grace of this kind in men by means of the angels.

Reply Obj. 3: The work of the instrument is ascribed to the princ.i.p.al agent by whose power the instrument acts. And since a minister is like an instrument, prophetic revelation, which is conveyed by the ministry of the angels, is said to be Divine.

THIRD ARTICLE [II-II, Q. 172, Art. 3]

Whether a Natural Disposition Is Requisite for Prophecy?

Objection 1: It would seem that a natural disposition is requisite for prophecy. For prophecy is received by the prophet according to the disposition of the recipient, since a gloss of Jerome on Amos 1:2, "The Lord will roar from Sion," says: "Anyone who wishes to make a comparison naturally turns to those things of which he has experience, and among which his life is spent. For example, sailors compare their enemies to the winds, and their losses to a shipwreck.

In like manner Amos, who was a shepherd, likens the fear of G.o.d to that which is inspired by the lion's roar." Now that which is received by a thing according to the mode of the recipient requires a natural disposition. Therefore prophecy requires a natural disposition.

Obj. 2: Further, the considerations of prophecy are more lofty than those of acquired science. Now natural indisposition hinders the considerations of acquired science, since many are prevented by natural indisposition from succeeding to grasp the speculations of science. Much more therefore is a natural disposition requisite for the contemplation of prophecy.

Obj. 3: Further, natural indisposition is a much greater obstacle than an accidental impediment. Now the considerations of prophecy are hindered by an accidental occurrence. For Jerome says in his commentary on Matthew [*The quotation is from Origen, Hom. vi in Num.] that "at the time of the marriage act, the presence of the Holy Ghost will not be vouchsafed, even though it be a prophet that fulfils the duty of procreation." Much more therefore does a natural indisposition hinder prophecy; and thus it would seem that a good natural disposition is requisite for prophecy.

_On the contrary,_ Gregory says in a homily for Pentecost (x.x.x in Ev.): "He," namely the Holy Ghost, "fills the boy harpist and makes him a Psalmist; He fills the herdsman plucking wild figs, and makes him a prophet." Therefore prophecy requires no previous disposition, but depends on the will alone of the Holy Ghost, of Whom it is written (1 Cor. 12:2): "All these things, one and the same Spirit worketh, dividing to every one according as He will."
