OF THEFT AND ROBBERY (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?

(6) Whether theft is a mortal sin?

(7) Whether it is lawful to thieve in a case of necessity?

(8) Whether every robbery is a mortal sin?

(9) Whether robbery is a more grievous sin than theft?
