A person who thievishly appropriates small sums, but whose pilferings have no moral reference to each other, will find himself a mortal offender the moment his accumulated injustices reach the amount we have qualified as notable, provided he be at that moment aware of the fact, or even if he only have a doubt about the matter. And this is true whether the stolen sums be taken from one or from several persons. Even in the latter case, although no one person suffers serious damage or prejudice, justice however is seriously violated and the intention of the guilty party is really to perpetrate grave injustice.
However, such thefts as these which in the end become accumulative, must of their nature be successive and joined together by some bond of moral union, otherwise they could never be considered a. whole. By this is meant that there must not exist between the different single thefts an interruption or space of time such as to make it impossible to consider reasonably the several deeds as forming one general action. The time generally looked upon as sufficient to prevent a moral union of this kind is two months. In the absence therefore of a specific intention to arrive at a large amount by successive thefts, it must be said that such thefts as are separated by an intervening space of two months can never be accounted as parts of one grave injustice, and a mortal sin can never be committed by one whose venial offenses are of this nature. Of course if there be an evil purpose, that alone is sufficient to establish a moral union between single acts of theft however considerable the interval that separates them.
Several persons may conspire to purloin each a limited amount. The circumstance of conspiracy, connivance or collusion makes each co-operator in the deed responsible for the whole damage done; and if the amount thus defrauded be notable, each is guilty of mortal sin.
We might here add in favor of children who take small things from their parents and of wives who sometimes relieve their husbands of small change, that it is natural that a man be less reluctant to being defrauded in small matters by his own than by total Strangers. It is only reasonable therefore that more latitude be allowed such delinquents when there is question of computing the amount to be considered notable; perhaps the amount might be doubled in their favor. The same might be said in favor of those whose petty thefts are directed against several victims instead of one, since the injury sustained individually is less.
The best plan is to leave what does not belong to one severely alone. In other sins there may be something gained in the long run, but here no such illusion can be entertained, for the spectre of restitution, as we shall see, follows every injustice as a shadow follows its object, and its business is to see that no man profit by his ill-gotten goods.
