Of Theft and Robbery

God has sovereign dominion over all things: and He, according to His providence, directed certain things to the sustenance of man's body. For this reason man has a natural dominion over things, as regards the power to make use of them.

The rich man is reproved for deeming external things to belong to him principally, as though he had not received them from another, namely from God.

This argument considers the dominion over external things as regards their nature. Such a dominion belongs to God alone, as stated above.

Community of goods is ascribed to the natural law, not that the natural law dictates that all things should be possessed in common and that nothing should be possessed as one's own: but because the division of possessions is not according to the natural law, but rather arose from human agreement which belongs to positive law, as stated above (Q. 57, AA. 2, 3). Hence the ownership of possessions is not contrary to the natural law, but an addition thereto devised by human reason.

A man would not act unlawfully if by going beforehand to the play he prepared the way for others: but he acts unlawfully if by so doing he hinders others from going. In like manner a rich man does not act unlawfully if he anticipates someone in taking possession of something which at first was common property, and gives others a share: but he sins if he excludes others indiscriminately from using it. Hence Basil says (Hom. in Luc. xii, 18): "Why are you rich while another is poor, unless it be that you may have the merit of a good stewardship, and he the reward of patience?"

When Ambrose says: "Let no man call his own that which is common," he is speaking of ownership as regards use, wherefore he adds: "He who spends too much is a robber."

Secrecy is sometimes a cause of sin, as when a man employs secrecy in order to commit a sin, for instance in fraud and guile. In this way it does not diminish sin, but constitutes a species of sin: and thus it is in theft. In another way secrecy is merely a circumstance of sin, and thus it diminishes sin, both because it is a sign of shame, and because it removes scandal.

To keep back what is due to another, inflicts the same kind of injury as taking a thing unjustly: wherefore an unjust detention is included in an unjust taking.

Nothing prevents that which belongs to one person simply, from belonging to another in some respect: thus a deposit belongs simply to the depositor, but with regard to its custody it is the depositary's, and the thing stolen is the thief's, not simply, but as regards its custody.

In the other kinds of sin the sinful nature is not derived from something involuntary, as in the sins opposed to justice: and so where there is a different kind of involuntary, there is a different species of sin.

The remote end of robbery and theft is the same. But this is not enough for identity of species, because there is a difference of proximate ends, since the robber wishes to take a thing by his own power, but the thief, by cunning.

The robbery of a woman cannot be secret on the part of the woman who is taken: wherefore even if it be secret as regards the others from whom she is taken, the nature of robbery remains on the part of the woman to whom violence is done.

It is no theft for a man to take another's property either secretly or openly by order of a judge who has commanded him to do so, because it becomes his due by the very fact that it is adjudicated to him by the sentence of the court. Hence still less was it a theft for the Israelites to take away the spoils of the Egyptians at the command of the Lord, Who ordered this to be done on account of the ill-treatment accorded to them by the Egyptians without any cause: wherefore it is written significantly (Wis. 10:19): "The just took the spoils of the wicked."

With regard to treasure-trove a distinction must be made. For some there are that were never in anyone's possession, for instance precious stones and jewels, found on the seashore, and such the finder is allowed to keep [Dig. I, viii, De divis. rerum: Inst. II, i, De rerum divis.]. The same applies to treasure hidden underground long since and belonging to no man, except that according to civil law the finder is bound to give half to the owner of the land, if the treasure trove be in the land of another person [Inst. II, i, 39: Cod. X, xv, De Thesauris]. Hence in the parable of the Gospel (Matt. 13:44) it is said of the finder of the treasure hidden in a field that he bought the field, as though he purposed thus to acquire the right of possessing the whole treasure. On the other Land the treasure-trove may be nearly in someone's possession: and then if anyone take it with the intention, not of keeping it but of returning it to the owner who does not look upon such things as unappropriated, he is not guilty of theft. In like manner if the thing found appears to be unappropriated, and if the finder believes it to be so, although he keep it, he does not commit a theft [Inst. II, i, 47]. In any other case the sin of theft is committed [Dig. XLI, i, De acquirend. rerum dominio, 9: Inst. II, i, 48]: wherefore Augustine says in a homily (Serm. clxxviii; De Verb. Apost.): "If thou hast found a thing and not returned it, thou hast stolen it" (Dig. xiv, 5, can. Si quid invenisti).

He who by stealth takes his own property which is deposited with another man burdens the depositary, who is bound either to restitution, or to prove himself innocent. Hence he is clearly guilty of sin, and is bound to ease the depositary of his burden. On the other hand he who, by stealth, takes his own property, if this be unjustly detained by another, he sins indeed; yet not because he burdens the retainer, and so he is not bound to restitution or compensation: but he sins against general justice by disregarding the order of justice and usurping judgment concerning his own property. Hence he must make satisfaction to God and endeavor to allay whatever scandal he may have given his neighbor by acting this way.

The statement that theft is not a great fault is in view of two cases. First, when a person is led to thieve through necessity. This necessity diminishes or entirely removes sin, as we shall show further on (A. 7). Hence the text continues: "For he stealeth to fill his hungry soul." Secondly, theft is stated not to be a great fault in comparison with the guilt of adultery, which is punished with death. Hence the text goes on to say of the thief that "if he be taken, he shall restore sevenfold . . . but he that is an adulterer . . . shall destroy his own soul."

The punishments of this life are medicinal rather than retributive. For retribution is reserved to the Divine judgment which is pronounced against sinners "according to truth" (Rom. 2:2). Wherefore, according to the judgment of the present life the death punishment is inflicted, not for every mortal sin, but only for such as inflict an irreparable harm, or again for such as contain some horrible deformity. Hence according to the present judgment the pain of death is not inflicted for theft which does not inflict an irreparable harm, except when it is aggravated by some grave circumstance, as in the case of sacrilege which is the theft of a sacred thing, of peculation, which is theft of common property, as Augustine states (Tract. 1, Super Joan.), and of kidnaping which is stealing a man, for which the pain of death is inflicted (Ex. 21:16).

Reason accounts as nothing that which is little: so that a man does not consider himself injured in very little matters: and the person who takes such things can presume that this is not against the will of the owner. And if a person take such like very little things, he may be proportionately excused from mortal sin. Yet if his intention is to rob and injure his neighbor, there may be a mortal sin even in these very little things, even as there may be through consent in a mere thought.

This decretal considers cases where there is no urgent need.

It is not theft, properly speaking, to take secretly and use another's property in a case of extreme need: because that which he takes for the support of his life becomes his own property by reason of that need.

In a case of a like need a man may also take secretly another's property in order to succor his neighbor in need.

A distinction must be made in the matter of spoils. For if they who take spoils from the enemy, are waging a just war, such things as they seize in the war become their own property. This is no robbery, so that they are not bound to restitution. Nevertheless even they who are engaged in a just war may sin in taking spoils through cupidity arising from an evil intention, if, to wit, they fight chiefly not for justice but for spoil. For Augustine says (De Verb. Dom. xix; Serm. lxxxii) that "it is a sin to fight for booty." If, however, those who take the spoil, are waging an unjust war, they are guilty of robbery, and are bound to restitution.

Unbelievers possess their goods unjustly in so far as they are ordered by the laws of earthly princes to forfeit those goods. Hence these may be taken violently from them, not by private but by public authority.

It is no robbery if princes exact from their subjects that which is due to them for the safe-guarding of the common good, even if they use violence in so doing: but if they extort something unduly by means of violence, it is robbery even as burglary is. Hence Augustine says (De Civ. Dei iv, 4): "If justice be disregarded, what is a king but a mighty robber? since what is a robber but a little king?" And it is written (Ezech. 22:27): "Her princes in the midst of her, are like wolves ravening the prey." Wherefore they are bound to restitution, just as robbers are, and by so much do they sin more grievously than robbers, as their actions are fraught with greater and more universal danger to public justice whose wardens they are.

—

Men who adhere to sensible things think more of external strength which is evidenced in robbery, than of internal virtue which is forfeit through sin: wherefore they are less ashamed of robbery than of theft.

Although more persons may be injured by theft than by robbery, yet more grievous injuries may be inflicted by robbery than by theft: for which reason also robbery is more odious.
