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 God are well ordered [*Vulg.: 'Those that are, are ordained of God.']." 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 God 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 God 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 to Objection 1: Charity which makes man a friend of God, is a perfection of the will, in which God 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 FP, Q[111], A[1], wherefore the comparison fails between the two.
Reply to Objection 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 to Objection 3: The work of the instrument is ascribed to the principal 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.
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 God 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.
Objection 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.
Objection 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 (xxx 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."
I answer that, As stated above (A[1]), prophecy in its true and exact sense comes from Divine inspiration; while that which comes from a natural cause is not called prophecy except in a relative sense. Now we must observe that as God Who is the universal efficient cause requires neither previous matter nor previous disposition of matter in His corporeal effects, for He is able at the same instant to bring into being matter and disposition and form, so neither does He require a previous disposition in His spiritual effects, but is able to produce both the spiritual effect and at the same time the fitting disposition as requisite according to the order of nature. More than this, He is able at the same time, by creation, to produce the subject, so as to dispose a soul for prophecy and give it the prophetic grace, at the very instant of its creation.
Reply to Objection 1: It matters not to prophecy by what comparisons the thing prophesied is expressed; and so the Divine operation makes no change in a prophet in this respect. Yet if there be anything in him incompatible with prophecy, it is removed by the Divine power.
Reply to Objection 2: The considerations of science proceed from a natural cause, and nature cannot work without a previous disposition in matter. This cannot be said of God Who is the cause of prophecy.
Reply to Objection 3: A natural indisposition, if not removed, might be an obstacle to prophetic revelation, for instance if a man were altogether deprived of the natural senses. In the same way a man might be hindered from the act of prophesying by some very strong passion, whether of anger, or of concupiscence as in coition, or by any other passion. But such a natural indisposition as this is removed by the Divine power, which is the cause of prophecy.
Whether a good life is requisite for prophecy?
Objection 1: It would seem that a good life is requisite for prophecy. For it is written ( Wis. 7:27 ) that the wisdom of God "through nations conveyeth herself into holy souls," and "maketh the friends of God, and prophets." Now there can be no holiness without a good life and sanctifying grace. Therefore prophecy cannot be without a good life and sanctifying grace.
Objection 2: Further, secrets are not revealed save to a friend, according to Jn. 15:15, "But I have called you friends, because all things whatsoever I have heard of My Father, I have made known to you." Now God reveals His secrets to the prophets ( Amos 3:7 ). Therefore it would seem that the prophets are the friends of God; which is impossible without charity. Therefore seemingly prophecy cannot be without charity; and charity is impossible without sanctifying grace.
Objection 3: Further, it is written ( Mat. 7:15 ): "Beware of false prophets, who come to you in the clothing of sheep, but inwardly they are ravening wolves." Now all who are without grace are likened inwardly to a ravening wolf, and consequently all such are false prophets. Therefore no man is a true prophet except he be good by grace.
Objection 4: Further, the Philosopher says (De Somn. et Vigil. [*Cf. De Divinat. per Somn. i, which is annexed to the work quoted]) that "if interpretation of dreams is from God, it is unfitting for it to be bestowed on any but the best." Now it is evident that the gift of prophecy is from God. Therefore the gift of prophecy is vouchsafed only to the best men.
On the contrary, To those who had said, "Lord, have we not prophesied in Thy name?" this reply is made: "I never knew you" ( Matt. 7:22 , 23 ). Now "the Lord knoweth who are His" ( 2 Tim. 2:19 ). Therefore prophecy can be in those who are not God's by grace.
I answer that, A good life may be considered from two points of view. First, with regard to its inward root, which is sanctifying grace. Secondly, with regard to the inward passions of the soul and the outward actions. Now sanctifying grace is given chiefly in order that man's soul may be united to God by charity. Wherefore Augustine says (De Trin. xv, 18): "A man is not transferred from the left side to the right, unless he receive the Holy Ghost, by Whom he is made a lover of God and of his neighbor." Hence whatever can be without charity can be without sanctifying grace, and consequently without goodness of life. Now prophecy can be without charity; and this is clear on two counts. First, on account of their respective acts: for prophecy pertains to the intellect, whose act precedes the act of the will, which power is perfected by charity. For this reason the Apostle ( 1 Cor. 13 ) reckons prophecy with other things pertinent to the intellect, that can be had without charity. Secondly, on account of their respective ends. For prophecy like other gratuitous graces is given for the good of the Church, according to 1 Cor. 12:7, "The manifestation of the Spirit is given to every man unto profit"; and is not directly intended to unite man's affections to God, which is the purpose of charity. Therefore prophecy can be without a good life, as regards the first root of this goodness.
If, however, we consider a good life, with regard to the passions of the soul, and external actions, from this point of view an evil life is an obstacle to prophecy. For prophecy requires the mind to be raised very high in order to contemplate spiritual things, and this is hindered by strong passions, and the inordinate pursuit of external things. Hence we read of the sons of the prophets (4 Kings 4:38) that they "dwelt together with [Vulg.: 'before']" Eliseus, leading a solitary life, as it were, lest worldly employment should be a hindrance to the gift of prophecy.
Reply to Objection 1: Sometimes the gift of prophecy is given to a man both for the good of others, and in order to enlighten his own mind; and such are those whom Divine wisdom, "conveying itself" by sanctifying grace to their minds, "maketh the friends of God, and prophets." Others, however, receive the gift of prophecy merely for the good of others. Hence Jerome commenting on Mat. 7:22, says: "Sometimes prophesying, the working of miracles, and the casting out of demons are accorded not to the merit of those who do these things, but either to the invoking the name of Christ, or to the condemnation of those who invoke, and for the good of those who see and hear."
Reply to Objection 2: Gregory [*Hom. xxvii in Ev.] expounding this passage [*Jn. 15:15] says: "Since we love the lofty things of heaven as soon as we hear them, we know them as soon as we love them, for to love is to know. Accordingly He had made all things known to them, because having renounced earthly desires they were kindled by the torches of perfect love." In this way the Divine secrets are not always revealed to prophets.
Reply to Objection 3: Not all wicked men are ravening wolves, but only those whose purpose is to injure others. For Chrysostom says [*Opus Imperf. in Matth., Hom. xix, among the works of St. John Chrysostom, and falsely ascribed to him] that "Catholic teachers, though they be sinners, are called slaves of the flesh, but never ravening wolves, because they do not purpose the destruction of Christians." And since prophecy is directed to the good of others, it is manifest that such are false prophets, because they are not sent for this purpose by God.
