On the contrary, It is written ( Rom. 1:32 ): "They who do such things are worthy of death, and not only they that do them, but also they that consent to them that do them." Therefore in like manner they that consent are bound to restitution.
I answer that, As stated above (A[6]), a person is bound to restitution not only on account of someone else's property which he has taken, but also on account of the injurious taking. Hence whoever is cause of an unjust taking is bound to restitution. This happens in two ways, directly and indirectly. Directly, when a man induces another to take, and this in three ways. First, on the part of the taking, by moving a man to take, either by express command, counsel, or consent, or by praising a man for his courage in thieving. Secondly, on the part of the taker, by giving him shelter or any other kind of assistance. Thirdly, on the part of the thing taken, by taking part in the theft or robbery, as a fellow evil-doer. Indirectly, when a man does not prevent another from evil-doing (provided he be able and bound to prevent him), either by omitting the command or counsel which would hinder him from thieving or robbing, or by omitting to do what would have hindered him, or by sheltering him after the deed. All these are expressed as follows:
"By command, by counsel, by consent, by flattery, by receiving, by participation, by silence, by not preventing, by not denouncing."
It must be observed, however, that in five of these cases the cooperator is always bound to restitution. First, in the case of command: because he that commands is the chief mover, wherefore he is bound to restitution principally. Secondly, in the case of consent; namely of one without whose consent the robbery cannot take place. Thirdly, in the case of receiving; when, to wit, a man is a receiver of thieves, and gives them assistance. Fourthly, in the case of participation; when a man takes part in the theft and in the booty. Fifthly, he who does not prevent the theft, whereas he is bound to do so; for instance, persons in authority who are bound to safeguard justice on earth, are bound to restitution, if by their neglect thieves prosper, because their salary is given to them in payment of their preserving justice here below.
In the other cases mentioned above, a man is not always bound to restitution: because counsel and flattery are not always the efficacious cause of robbery. Hence the counsellor or flatterer is bound to restitution, only when it may be judged with probability that the unjust taking resulted from such causes.
Reply to Objection 1: Not only is he bound to restitution who commits the sin, but also he who is in any way cause of the sin, whether by counselling, or by commanding, or in any other way whatever.
Reply to Objection 2: He is bound chiefly to restitution, who is the principal in the deed; first of all, the "commander"; secondly, the "executor," and in due sequence, the others: yet so that, if one of them make restitution, another is not bound to make restitution to the same person. Yet those who are principals in the deed, and who took possession of the thing, are bound to compensate those who have already made restitution. When a man commands an unjust taking that does not follow, no restitution has to be made, since its end is chiefly to restore the property of the person who has been unjustly injured.
Reply to Objection 3: He that fails to denounce a thief or does not withstand or reprehend him is not always bound to restitution, but only when he is obliged, in virtue of his office, to do so: as in the case of earthly princes who do not incur any great danger thereby; for they are invested with public authority, in order that they may maintain justice.
Whether a man is bound to immediate restitution, or may he put it off?
Objection 1: It would seem that a man is not bound to immediate restitution, and can lawfully delay to restore. For affirmative precepts do not bind for always. Now the necessity of making restitution is binding through an affirmative precept. Therefore a man is not bound to immediate restitution.
Objection 2: Further, no man is bound to do what is impossible. But it is sometimes impossible to make restitution at once. Therefore no man is bound to immediate restitution.
Objection 3: Further, restitution is an act of virtue, viz. of justice. Now time is one of the circumstances requisite for virtuous acts. Since then the other circumstances are not determinate for acts of virtue, but are determinable according to the dictate of prudence, it seems that neither in restitution is there any fixed time, so that a man be bound to restore at once.
On the contrary, All matters of restitution seem to come under one head. Now a man who hires the services of a wage-earner, must not delay compensation, as appears from Lev. 19:13, "The wages of him that hath been hired by thee shall not abide with thee until the morning." Therefore neither is it lawful, in other cases of restitution, to delay, and restitution should be made at once.
I answer that, Even as it is a sin against justice to take another's property, so also is it to withhold it, since, to withhold the property of another against the owner's will, is to deprive him of the use of what belongs to him, and to do him an injury. Now it is clear that it is wrong to remain in sin even for a short time; and one is bound to renounce one's sin at once, according to Ecclus. 21:2, "Flee from sin as from the face of a serpent." Consequently one is bound to immediate restitution, if possible, or to ask for a respite from the person who is empowered to grant the use of the thing.
Reply to Objection 1: Although the precept about the making of restitution is affirmative in form, it implies a negative precept forbidding us to withhold another's property.
Reply to Objection 2: When one is unable to restore at once, this very inability excuses one from immediate restitution: even as a person is altogether excused from making restitution if he is altogether unable to make it. He is, however, bound either himself or through another to ask the person to whom he owes compensation to grant him a remission or a respite.
Reply to Objection 3: Whenever the omission of a circumstance is contrary to virtue that circumstance must be looked upon as determinate, and we are bound to observe it: and since delay of restitution involves a sin of unjust detention which is opposed to just detention, it stands to reason that the time is determinate in the point of restitution being immediate.
