CATECHISM OF THE CATHOLIC CHURCH
SECOND EDITION

Paragraphs 2452–2456

2452 The goods of creation are destined for the entire human race. The right to private property does not abolish the universal destination of goods.
2453 The seventh commandment forbids theft. Theft is the usurpation of another's goods against the reasonable will of the owner.
2454 Every manner of taking and using another's property unjustly is contrary to the seventh commandment. The injustice committed requires reparation. Commutative justice requires the restitution of stolen goods.
2455 The moral law forbids acts which, for commercial or totalitarian purposes, lead to the enslavement of human beings, or to their being bought, sold or exchanged like merchandise.
2456 The dominion granted by the Creator over the mineral, vegetable, and animal resources of the universe cannot be separated from respect for moral obligations, including those toward generations to come.
