Family life is too intimate to be preserved by the spirit of justice. It can only be sustained by a spirit of love which goes beyond justice. Justice requires that we carefully weigh rights and privileges and assure that each member of a community receives his due share. Love does not weigh rights and privileges too carefully because it prompts each to bear the burden of the other.
Inasmuch as the domestic household is antecedent, as well as in idea as in fact, the family must necessarily have rights and duties which are prior than those of the Community and founded more immediately in nature.
Private property is a natural fruit of labor, a product of intense activity of man, acquired through his energetic determination to ensure and develop with his own strength his own existence and that of his family, and to create for himself and his own an existence of just freedom, not only economic, but also political, cultural and religious.
