This Commandment forbids taking or keeping other people's goods unlawfully or for procuring loss to our neighbor in his possessions in any other way.
Stealing is taking away other people's belongings against the will of the owner, that is to say, when he has every reason and right to be unwilling to be deprived of them. Stealing is against justice, and it wrongs our neighbor by taking away from him and retaining, against his own good right and wish, what is his. Our neighbor's possessions are whatever belongs to him, and that of which he has the property or use, or which he holds on deposit.
The Seventh Commandment may be broken in two ways: by theft, or by robbery. Theft is taking what belongs to others secretly; robbery is taking it with violence and openly.
Things belonging to another may be taken if the owner is not opposed to it, or if his opposition is unjust, as might happen in the case of someone in extreme necessity, provided that he were to take only as much as was strictly indispensable to suffice for his urgent and extreme necessity. Furthermore, anyone may be injured in his belongings not only by theft and robbery, but also by means of fraud or usury, or of any other unjust procedure with regard to his property. Fraud occurs when anyone is cheated in business by false weights, measures or money, or by bad goods, by forging writings or documents; finally, by practicing deceit in purchasing or selling, and in any other sort of contract, and also by being unwilling to give what is just or what has been agreed upon. Usury occurs when unlawful interest is exacted without any legitimate claim for any loan, taking advantage of the need or ignorance of another.
Other kinds of injustice to anyone in respect of his property are: making him lose unjustly what is his, doing him injury in his possessions, not working as one ought, maliciously withholding payment of debts or commercial obligations, striking or killing any of his animals, dissipating what is held in trust for him, interfering with his obtaining any just gain, abetting thieves by receiving, concealing or selling stolen goods.
Stealing is a grave sin against justice when any serious matter is involved, for it is of much importance to respect the right of the owner to his property, and this is for the good of individuals, of families and of society. The matter is grave when something considerable is taken, or even when something of little worth, if it occasions serious loss to the owner.
The Seventh Commandment orders us to respect other people's property, to give fair pay to workmen, and to observe what is just in all that concerns the belongings of others. If anyone commits a sin against the Seventh Commandment, it is not enough to confess the sin, but it is necessary to do what is possible to restore what has been stolen, and to make good the loss. The making good of the loss is the compensation which must be given to the owner of the goods or gains lost through the theft or other injustice committed to his disadvantage. This compensation must be made either to the owner or to his heirs. If he be dead, and if this be really impossible, the value must be given to the poor or made up by pious works.
Supposing something of considerable value is found, the finder is bound to use the utmost diligence to find the owner, and to give it back to him.
