Reply Obj. 3: The fact that the wife voluntarily consents to the adultery, lessens the sin and injury, so far as the woman is concerned, for it would be more grievous, if the adulterer oppressed her by violence. But this does not remove the injury as affecting her husband, since "the wife hath not power of her own body; but the husband" (1 Cor. 7:4). The same applies to similar cases. Of adultery, however, as it is opposed not only to justice but also to chastity, we shall speak in the treatise on Temperance (Q. 154, A. 8). _______________________
QUESTION 66
OF THEFT AND ROBBERY
(In Nine Articles)
We must now consider the sins opposed to justice, whereby a man injures his neighbor in his belongings; namely theft and robbery.
Under this head there are nine points of inquiry:
(1) Whether it is natural to man to possess external things?
(2) Whether it is lawful for a man to possess something as his own?
(3) Whether theft is the secret taking of another's property?
(4) Whether robbery is a species of sin distinct from theft?
(5) Whether every theft is a sin?
