Summa Theologica by Saint Thomas Aquinas (whitelam books .TXT) 📕

QQ. 92, 94), superstition denotes undue divine worship. Now a thing pertains to the worship of God in two ways: in one way, it is something offered to God; as a sacrifice, an oblation, or something of the kind: in another way, it is something divine that is assumed, as stated above with regard to an oath (Q. 89, A. 4, ad 2). Wherefore superstition includes not only idolatrous sacrifices offered to demons, but also recourse to the help of the demons for the purpose of doing or knowing something. But all divination results from the demons' operation, either because the demons are expressly invoked that the future may be made known, or because the demons thrust themselves into futile searchings of the future, in order to entangle men's minds with vain conceits. Of this kind of vanity it is written (Ps. 39:5): "Who hath not regard to vanities and lying follies." Now it is vain to seek knowledge of the future, when one tries to get it from a source whence it cannot be foreknown. Therefore it is manifest that divination is a species of superstition.

Reply Obj. 1: Divination is a kind of curiosity with regard to the end in view, which is foreknowledge of the future; but it is a kind of superstition as regards the mode of operation.

Reply Obj. 2: This kind of divination pertains to the worship of the demons, inasmuch as one enters into a compact, tacit or express with the demons.

Reply Obj. 3: In the New Law man's mind is restrained from solicitude about temporal things: wherefore the New Law contains no institution for the foreknowledge of future events in temporal matters. On the other hand in the Old Law, which contained earthly promises, there were consultations about the future in connection with religious matters. Hence where it is written (Isa. 8:19): "And when they shall say to you: Seek of pythons and of diviners, who mutter in their enchantments," it is added by way of answer: "Should not the people seek of their God, a vision for the living and the dead? [*Vulg.: 'seek of their God, for the living of the dead?']"

In the New Testament, however, there were some possessed of the spirit of prophecy, who foretold many things about future events. _______________________

THIRD ARTICLE [II-II, Q. 95, Art. 3]

Whether We Ought to Distinguish Several Species of Divination?

Objection 1: It would seem that we should not distinguish several species of divination. Where the formality of sin is the same, there are not seemingly several species of sin. Now there is one formality of sin in all divinations, since they consist in entering into compact with the demons in order to know the future. Therefore there are not several species of divination.

Obj. 2: Further, a human act takes its species from its end, as stated above (I-II, Q. 1, A. 3; Q. 18, A. 6). But all divination is directed to one end, namely, the foretelling of the future. Therefore all divinations are of one species.

Obj. 3: Further, signs do not vary the species of a sin, for whether one detracts by word, writing or gestures, it is the same species of sin. Now divinations seem to differ merely according to the various signs whence the foreknowledge of the future is derived. Therefore there are not several species of divination.

On the contrary, Isidore enumerates various species of divination (Etym. viii, 9).

I answer that, As stated above (A. 2), all divinations seek to acquire foreknowledge of future events, by means of some counsel and help of a demon, who is either expressly called upon to give his help, or else thrusts himself in secretly, in order to foretell certain future things unknown to men, but known to him in such manners as have been explained in the First Part (Q. 57, A. 3). When demons are expressly invoked, they are wont to foretell the future in many ways. Sometimes they offer themselves to human sight and hearing by mock apparitions in order to foretell the future: and this species is called "prestigiation" because man's eyes are blindfolded (praestringuntur). Sometimes they make use of dreams, and this is called "divination by dreams": sometimes they employ apparitions or utterances of the dead, and this species is called "necromancy," for as Isidore observes (Etym. viii) in Greek, "nekron means dead, and manteia divination, because after certain incantations and the sprinkling of blood, the dead seem to come to life, to divine and to answer questions." Sometimes they foretell the future through living men, as in the case of those who are possessed: this is divination by "pythons," of whom Isidore says that "pythons are so called from Pythius Apollo, who was said to be the inventor of divination." Sometimes they foretell the future by means of shapes or signs which appear in inanimate beings. If these signs appear in some earthly body such as wood, iron or polished stone, it is called "geomancy," if in water "hydromancy," if in the air "aeromancy," if in fire "pyromancy," if in the entrails of animals sacrificed on the altars of demons, "aruspicy."

The divination which is practiced without express invocation of the demons is of two kinds. The first is when, with a view to obtain knowledge of the future, we take observations in the disposition of certain things. If one endeavor to know the future by observing the position and movements of the stars, this belongs to "astrologers," who are also called "genethliacs," because they take note of the days on which people are born. If one observe the movements and cries of birds or of any animals, or the sneezing of men, or the sudden movements of limbs, this belongs in general to "augury," which is so called from the chattering of birds (avium garritu), just as "auspice" is derived from watching birds (avium inspectione). These are chiefly wont to be observed in birds, the former by the ear, the latter by the eye. If, however, these observations have for their object men's words uttered unintentionally, which someone twist so as to apply to the future that he wishes to foreknow, then it is called an "omen": and as Valerius Maximus [*De Dict. Fact. Memor. i, 5] remarks, "the observing of omens has a touch of religion mingled with it, for it is believed to be founded not on a chance movement, but on divine providence. It was thus that when the Romans were deliberating whether they would change their position, a centurion happened to exclaim at the time: 'Standard-bearer, fix the banner, we had best stand here': and on hearing these words they took them as an omen, and abandoned their intention of advancing further." If, however, the observation regards the dispositions, that occur to the eye, of figures in certain bodies, there will be another species of divination: for the divination that is taken from observing the lines of the hand is called "chiromancy," i.e. divination of the hand (because cheir is the Greek for hand): while the divination which is taken from signs appearing in the shoulder-blades of an animal is called "spatulamancy."

To this second species of divination, which is without express invocation of the demons, belongs that which is practiced by observing certain things done seriously by men in the research of the occult, whether by drawing lots, which is called "geomancy"; or by observing the shapes resulting from molten lead poured into water; or by observing which of several sheets of paper, with or without writing upon them, a person may happen to draw; or by holding out several unequal sticks and noting who takes the greater or the lesser, or by throwing dice, and observing who throws the highest score; or by observing what catches the eye when one opens a book, all of which are named "sortilege."

Accordingly it is clear that there are three kinds of divination. The first is when the demons are invoked openly, this comes under the head of "necromancy"; the second is merely an observation of the disposition or movement of some other being, and this belongs to "augury"; while the third consists in doing something in order to discover the occult; and this belongs to "sortilege." Under each of these many others are contained, as explained above.

Reply Obj. 1: In all the aforesaid there is the same general, but not the same special, character of sin: for it is much more grievous to invoke the demons than to do things that deserve the demons' interference.

Reply Obj. 2: Knowledge of the future or of the occult is the ultimate end whence divination takes its general formality. But the various species are distinguished by their proper objects or matters, according as the knowledge of the occult is sought in various things.

Reply Obj. 3: The things observed by diviners are considered by them, not as signs expressing what they already know, as happens in detraction, but as principles of knowledge. Now it is evident that diversity of principles diversifies the species, even in demonstrative sciences. _______________________

FOURTH ARTICLE [II-II, Q. 95, Art. 4]

Whether Divination Practiced by Invoking the Demons Is Unlawful?

Objection 1: It would seem that divination practiced by invoking the demons is not unlawful. Christ did nothing unlawful, according to 1 Pet. 2:22, "Who did no sin." Yet our Lord asked the demon: "What is thy name?" and the latter replied: "My name is Legion, for we are many" (Mk. 5:9). Therefore it seems lawful to question the demons about the occult.

Obj. 2: Further, the souls of the saints do not encourage those who ask unlawfully. Yet Samuel appeared to Saul when the latter inquired of the woman that had a divining spirit, concerning the issue of the coming war (1 Kings 28:8, sqq.). Therefore the divination that consists in questioning demons is not unlawful.

Obj. 3: Further, it seems lawful to seek the truth from one who knows, if it be useful to know it. But it is sometimes useful to know what is hidden from us, and can be known through the demons, as in the discovery of thefts. Therefore divination by questioning demons is not unlawful.

On the contrary, It is written (Deut. 18:10, 11): "Neither let there there be found among you . . . anyone that consulteth soothsayers . . . nor . . . that consulteth pythonic spirits."

I answer that, All divination by invoking demons is unlawful for two reasons. The first is gathered from the principle of divination, which is a compact made expressly with a demon by the very fact of invoking him. This is altogether unlawful; wherefore it is written against certain persons (Isa. 28:15): "You have said: We have entered into a league with death, and we have made a covenant with hell." And still more grievous would it be if sacrifice were offered or reverence paid to the demon invoked. The second reason is gathered from the result. For the demon who intends man's perdition endeavors, by his answers, even though he sometimes tells the truth, to accustom men to believe him, and so to lead him on to something prejudicial to the salvation of mankind. Hence Athanasius, commenting on the words of Luke 4:35, "He rebuked him, saying: Hold thy peace," says: "Although the demon confessed the truth, Christ put a stop to his speech, lest together with the truth he should publish his wickedness and accustom us to care little for such things, however much he may seem to speak the truth. For it is wicked, while we have the divine Scriptures, to seek knowledge from the demons."

Reply Obj. 1: According to Bede's commentary on Luke 8:30, "Our Lord inquired, not through ignorance, but in order that the disease, which he tolerated, being made public, the power of the Healer might shine forth more graciously." Now it is one thing to question a demon who comes to us of his own accord (and it is lawful to do so at times for the good of others, especially when he can be compelled, by the power of God, to tell the truth) and another to invoke a demon in order to gain from him knowledge of things hidden from us.

Reply Obj. 2: According to Augustine (Ad Simplic. ii, 3), "there is nothing absurd in believing that the spirit of the just man, being about to smite the king with the divine sentence, was permitted to appear to him, not by the sway of magic art or power, but by some occult dispensation of which neither the witch nor Saul was aware. Or else the spirit of Samuel was not in reality aroused from his rest, but some phantom or mock apparition formed by the machinations of the devil, and styled by Scripture under the name of Samuel, just as the images of things are wont to be called by the names of those things."

Reply Obj. 3:
