Q: Whether Idolatry Is the Gravest of Sins?

A: On the contrary,
A gloss on the saying of Lev. 15:25, about the uncleanness of a woman suffering from an issue of blood, says: "Every sin is an uncleanness of the soul, but especially idolatry."

I answer that,
The gravity of a sin may be considered in two ways. First, on the part of the sin itself, and thus idolatry is the most grievous sin. For just as the most heinous crime in an earthly commonwealth would seem to be for a man to give royal honor to another than the true king, since, so far as he is concerned, he disturbs the whole order of the commonwealth, so, in sins that are committed against God, which indeed are the greater sins, the greatest of all seems to be for a man to give God's honor to a creature, since, so far as he is concerned, he sets up another God in the world, and lessens the divine sovereignty. Secondly, the gravity of a sin may be considered on the part of the sinner. Thus the sin of one that sins knowingly is said to be graver than the sin of one that sins through ignorance: and in this way nothing hinders heretics, if they knowingly corrupt the faith which they have received, from sinning more grievously than idolaters who sin through ignorance. Furthermore other sins may be more grievous on account of greater contempt on the part of the sinner.

Reply Obj. 1: Idolatry presupposes internal unbelief, and to this it adds undue worship. But in a case of external idolatry without internal unbelief, there is an additional sin of falsehood, as stated above (A. 2).

Reply Obj. 2: Idolatry includes a grievous blasphemy, inasmuch as it deprives God of the singleness of His dominion and denies the faith by deeds.

Reply Obj. 3: Since it is essential to punishment that it be against the will, a sin whereby another sin is punished needs to be more manifest, in order that it may make the man more hateful to himself and to others; but it need not be a more grievous sin: and in this way the sin against nature is less grievous than the sin of idolatry. But since it is more manifest, it is assigned as a fitting punishment of the sin of idolatry, in order that, as by idolatry man abuses the order of the divine honor, so by the sin against nature he may suffer confusion from the abuse of his own nature.

Reply Obj. 4: Even as to the genus of the sin, the Manichean heresy is more grievous than the sin of other idolaters, because it is more derogatory to the divine honor, since they set up two gods in opposition to one another, and hold many vain and fabulous fancies about God. It is different with other heretics, who confess their belief in one God and worship Him alone.

Reply Obj. 5: The observance of the Law during the time of grace is not quite equal to idolatry as to the genus of the sin, but almost equal, because both are species of pestiferous superstition.
Q: Objection 1: It would seem that idolatry is not the gravest of sins. The worst is opposed to the best (Ethic. viii, 10). But interior worship, which consists of faith, hope and charity, is better than external worship. Therefore unbelief, despair and hatred of God, which are opposed to internal worship, are graver sins than idolatry, which is opposed to external worship.

Obj. 2: Further, the more a sin is against God the more grievous it is. Now, seemingly, a man acts more directly against God by blaspheming, or denying the faith, than by giving God's worship to another, which pertains to idolatry. Therefore blasphemy and denial of the faith are more grievous sins than idolatry.

Obj. 3: Further, it seems that lesser evils are punished with greater evils. But the sin of idolatry was punished with the sin against nature, as stated in Rom. 1:26. Therefore the sin against nature is a graver sin than idolatry.

Obj. 4: Further, Augustine says (Contra Faust. xx, 5): "Neither do we say that you," viz. the Manichees, "are pagans, or a sect of pagans, but that you bear a certain likeness to them since you worship many gods: and yet you are much worse than they are, for they worship things that exist, but should not be worshiped as gods, whereas you worship things that exist not at all." Therefore the vice of heretical depravity is more grievous than idolatry.

Obj. 5: Further, a gloss of Jerome on Gal. 4:9, "How turn you again to the weak and needy elements?" says: "The observance of the Law, to which they were then addicted, was a sin almost equal to the worship of idols, to which they had been given before their conversion." Therefore idolatry is not the most grievous sin.
Q: Objection 1: It would seem that the cause of idolatry was not on the part of man. In man there is nothing but either nature, virtue, or guilt. But the cause of idolatry could not be on the part of man's nature, since rather does man's natural reason dictate that there is one God, and that divine worship should not be paid to the dead or to inanimate beings. Likewise, neither could idolatry have its cause in man on the part of virtue, since "a good tree cannot bring forth evil fruit," according to Matt. 7:18: nor again could it be on the part of guilt, because, according to Wis. 14:27, "the worship of abominable idols is the cause and the beginning and end of all evil." Therefore idolatry has no cause on the part of man.

Obj. 2: Further, those things which have a cause in man are found among men at all times. Now idolatry was not always, but is stated [*Peter Comestor, Hist. Genes. xxxvii, xl] to have been originated either by Nimrod, who is related to have forced men to worship fire, or by Ninus, who caused the statue of his father Bel to be worshiped. Among the Greeks, as related by Isidore (Etym. viii, 11), Prometheus was the first to set up statues of men: and the Jews say that Ismael was the first to make idols of clay. Moreover, idolatry ceased to a great extent in the sixth age. Therefore idolatry had no cause on the part of man.

Obj. 3: Further, Augustine says (De Civ. Dei xxi, 6): "It was not possible to learn, for the first time, except from their" (i.e. the demons') "teaching, what each of them desired or disliked, and by what name to invite or compel him: so as to give birth to the magic arts and their professors": and the same observation seems to apply to idolatry. Therefore idolatry had no cause on the part of man.
Q: Objection 1: It would seem that divination is not a sin. Divination is derived from something
divine:
and things that are divine pertain to holiness rather than to sin. Therefore it seems that divination is not a sin.

Obj. 2: Further, Augustine says (De Lib. Arb. i, 1): "Who dares to say that learning is an evil?" and again: "I could nowise admit that intelligence can be an evil." But some arts are divinatory, as the Philosopher states (De Memor. i): and divination itself would seem to pertain to a certain intelligence of the truth. Therefore it seems that divination is not a sin.

Obj. 3: Further, there is no natural inclination to evil; because nature inclines only to its like. But men by natural inclination seek to foreknow future events; and this belongs to divination. Therefore divination is not a sin.
Q: Whether Divination Is a Species of Superstition?

A: On the contrary,
Origen says in his Peri Archon [*The quotation is from his sixteenth homily on the Book of Numbers]: "There is an operation of the demons in the administering of foreknowledge, comprised, seemingly, under the head of certain arts exercised by those who have enslaved themselves to the demons, by means of lots, omens, or the observance of shadows. I doubt not that all these things are done by the operation of the demons." Now, according to Augustine (De Doctr. Christ. ii, 20, 23), "whatever results from fellowship between demons and men is superstitious." Therefore divination is a species of superstition.

I answer that,
As stated above (A. 1; 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.
Q: Objection 1: It would seem that divination is not a species of superstition. The same thing cannot be a species of diverse genera. Now divination is apparently a species of curiosity, according to Augustine (De Vera Relig. xxxviii) [*Cf. De Doctr. Christ. ii, 23, 24; De Divin. Daem. 3]. Therefore it is not, seemingly, a species of superstition.

Obj. 2: Further, just as religion is due worship, so is superstition undue worship. But divination does not seem to pertain to undue worship. Therefore it does not pertain to superstition.

Obj. 3: Further, superstition is opposed to religion. But in true religion nothing is to be found corresponding as a contrary to divination. Therefore divination is not a species of superstition.
Q: 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.
Q: Whether Divination Practiced by Invoking the Demons Is Unlawful?

A: 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: No temporal utility can compare with the harm to spiritual health that results from the research of the unknown by invoking the demon.
Q: 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.
Q: Objection 1: It would seem that divination by the stars is not unlawful. It is lawful to foretell effects by observing their causes: thus a physician foretells death from the disposition of the disease. Now the heavenly bodies are the cause of what takes place in the world, according to Dionysius (Div. Nom. iv). Therefore divination by the stars is not unlawful.

Obj. 2: Further, human science originates from experiments, according to the Philosopher (Metaph. i, 1). Now it has been discovered through many experiments that the observation of the stars is a means whereby some future events may be known beforehand. Therefore it would seem not unlawful to make use of this kind of divination.

Obj. 3: Further, divination is declared to be unlawful in so far as it is based on a compact made with the demons. But divination by the stars contains nothing of the kind, but merely an observation of God's creatures. Therefore it would seem that this species of divination is not unlawful.
Q: Objection 1: It would seem that divination by dreams is not unlawful. It is not unlawful to make use of divine instruction. Now men are instructed by God in dreams, for it is written (Job 33:15, 16): "By a dream in a vision by night, when deep sleep falleth upon men, and they are sleeping in their beds, then He," God to wit, "openeth the ears of men, and teaching instructeth them in what they are to learn." Therefore it is not unlawful to make use of divination by dreams.

Obj. 2: Further, those who interpret dreams, properly speaking, make use of divination by dreams. Now we read of holy men interpreting dreams: thus Joseph interpreted the dreams of Pharaoh's butler and of his chief baker (Gen. 40), and Daniel interpreted the dream of the king of Babylon (Dan. 2, 4). Therefore divination by dreams is not unlawful.

Obj. 3: Further, it is unreasonable to deny the common experiences of men. Now it is the experience of all that dreams are significative of the future. Therefore it is useless to deny the efficacy of dreams for the purpose of divination, and it is lawful to listen to them.
Q: Objection 1: It would seem that divination by auguries, omens, and by like observations of external things is not unlawful. If it were unlawful holy men would not make use thereof. Now we read of Joseph that he paid attention to auguries, for it is related (Gen. 44:5) that Joseph's steward said: "The cup which you have stolen is that in which my lord drinketh and in which he is wont to divine (
augurari
)": and he himself afterwards said to his brethren (Gen. 44:15): "Know you not that there is no one like me in the science of divining?" Therefore it is not unlawful to make use of this kind of divination.

Obj. 2: Further, birds naturally know certain things regarding future occurrences of the seasons, according to Jer. 8:7, "The kite in the air hath known her time; the turtle, the swallow, and the stork have observed the time of their coming." Now natural knowledge is infallible and comes from God. Therefore it seems not unlawful to make use of the birds' knowledge in order to know the future, and this is divination by augury.

Obj. 3: Further, Gedeon is numbered among the saints (Heb. 11:32). Yet Gedeon made use of an omen, when he listened to the relation and interpreting of a dream (Judges 7:15): and Eliezer, Abraham's servant, acted in like manner (Gen. 24). Therefore it seems that this kind of divination is not unlawful.
Q: Objection 1: It would seem that divination by drawing lots is not unlawful, because a gloss of Augustine on Ps. 30:16, "My lots are in Thy hands," says: "It is not wrong to cast lots, for it is a means of ascertaining the divine will when a man is in doubt."

Obj. 2: There is, seemingly, nothing unlawful in the observances which the Scriptures relate as being practiced by holy men. Now both in the Old and in the New Testament we find holy men practicing the casting of lots. For it is related (Jos. 7:14, sqq.) that Josue, at the Lord's command, pronounced sentence by lot on Achan who had stolen of the anathema. Again Saul, by drawing lots, found that his son Jonathan had eaten honey (1 Kings 14:58, sqq.): Jonas, when fleeing from the face of the Lord, was discovered and thrown into the sea (Jonah 1:7, sqq.): Zacharias was chosen by lot to offer incense (Luke 1:9): and the apostles by drawing lots elected Matthias to the apostleship (Acts 1:26). Therefore it would seem that divination by lots is not unlawful.

Obj. 3: Further, fighting with the fists, or "monomachy," i.e. single combat as it is called, and trial by fire and water, which are called "popular" trials, seem to come under the head of sortilege, because something unknown is sought by their means. Yet these practices seem to be lawful, because David is related to have engaged in single combat with the Philistine (1 Kings 17:32, sqq.). Therefore it would seem that divination by lot is not unlawful.
Q: Objection 1: It would seem that it is not unlawful to practice the observances of the magic art. A thing is said to be unlawful in two ways. First, by reason of the genus of the deed, as murder and theft: secondly, through being directed to an evil end, as when a person gives an alms for the sake of vainglory. Now the observances of the magic art are not evil as to the genus of the deed, for they consist in certain fasts and prayers to God; moreover, they are directed to a good end, namely, the acquisition of science. Therefore it is not unlawful to practice these observances.

Obj. 2: Further, it is written (Dan. 1:17) that "to the children" who abstained, "God gave knowledge, and understanding in every book, and wisdom." Now the observances of the magic art consist in certain fasts and abstinences. Therefore it seems that this art achieves its results through God: and consequently it is not unlawful to practice it.

Obj. 3: Further, seemingly, as stated above (A. 1), the reason why it is wrong to inquire of the demons concerning the future is because they have no knowledge of it, this knowledge being proper to God. Yet the demons know scientific truths: because sciences are about things necessary and invariable, and such things are subject to human knowledge, and much more to the knowledge of demons, who are of keener intellect, as Augustine says [*Gen. ad lit. ii, 17; De Divin. Daemon. 3, 4]. Therefore it seems to be no sin to practice the magic art, even though it achieve its result through the demons.
Q: Objection 1: It would seem that observances directed to the alteration of bodies, as for the purpose of acquiring health, or the like, are lawful. It is lawful to make use of the natural forces of bodies in order to produce their proper effects. Now in the physical order things have certain occult forces, the reason of which man is unable to assign; for instance that the magnet attracts iron, and many like instances, all of which Augustine enumerates (De Civ. Dei xxi, 5, 7). Therefore it would seem lawful to employ such like forces for the alteration of bodies.

Obj. 2: Further, artificial bodies are subject to the heavenly bodies, just as natural bodies are. Now natural bodies acquire certain occult forces resulting from their species through the influence of the heavenly bodies. Therefore artificial bodies, e.g. images, also acquire from the heavenly bodies a certain occult force for the production of certain effects. Therefore it is not unlawful to make use of them and of such like things.

Obj. 3: Further, the demons too are able to alter bodies in many ways, as Augustine states (De Trin. iii, 8, 9). But their power is from God. Therefore it is lawful to make use of their power for the purpose of producing these alterations.
