That right to property, therefore, which has been proved to belong naturally to individual persons, must in like wise belong to a man in his capacity of head of a family; nay, that right is all the stronger in proportion as the human person receives a wider extension in the family group. It is a most sacred law of nature that a father should provide food and all necessaries for those whom he has begotten; and, similarly, it is natural that he should wish that his children, who carry on, so to speak, and continue his personality, should be by him provided with all that is needful to enable them to keep themselves decently from want and misery amid the uncertainties of this mortal life. Now, in no other way can a father effect this except by the ownership of productive property, which he can transmit to his children by inheritance. A family, no less than a State, is, as We have said, a true society, governed by an authority peculiar to itself, that is to say, by the authority of the father. Provided, therefore, the limits which are prescribed by the very purposes for which it exists be not transgressed, the family has at least equal rights with the State in the choice and pursuit of the things needful to its preservation and its just liberty. We say, “at least equal rights”; for, inasmuch as the domestic household is antecedent, as well in idea as in fact, to the gathering of men into a community, the family must necessarily have rights and duties which are prior to those of the community, and founded more immediately in nature. If the citizens, if the families on entering into association and fellowship, were to experience hindrance in a commonwealth instead of help, and were to find their rights attacked instead of being upheld, society would rightly be an object of detestation rather than of desire.

The contention, then, that the civil government should at its option intrude into and exercise intimate control over the family and the household is a great and pernicious error. True, if a family finds itself in exceeding distress, utterly deprived of the counsel of friends, and without any prospect of extricating itself, it is right that extreme necessity be met by public aid, since each family is a part of the commonwealth. In like manner, if within the precincts of the household there occur grave disturbance of mutual rights, public authority should intervene to force each party to yield to the other its proper due; for this is not to deprive citizens of their rights, but justly and properly to safeguard and strengthen them.** But the rulers of the commonwealth must go no further; here, nature bids them stop. Paternal authority can be neither abolished nor absorbed by the State; for it has the same source as human life itself.**

But if the question be asked: How must one’s possessions be used? - the Church replies without hesitation in the words of the same holy Doctor: “Man should not consider his material possessions as his own, but as common to all, so as to share them without hesitation when others are in need. Whence the Apostle with, ‘Command the rich of this world… to offer with no stint, to apportion largely.’” True, no one is commanded to distribute to others that which is required for his own needs and those of his household; nor even to give away what is reasonably required to keep up becomingly his condition in life, “for no one ought to live other than becomingly.” But, when what necessity demands has been supplied, and one’s standing fairly taken thought for, it becomes a duty to give to the indigent out of what remains over. “Of that which remaineth, give alms.” It is a duty, not of justice (save in extreme cases), but of Christian charity - a duty not enforced by human law.
…
The foremost duty, therefore, of the rulers of the State should be to make sure that the laws and institutions, the general character and administration of the commonwealth, shall be such as of themselves to realize public well-being and private prosperity. This is the proper scope of wise statesmanship and is the work of the rulers. Now a State chiefly prospers and thrives through moral rule, well-regulated family life, respect for religion and justice, the moderation and fair imposing of public taxes, the progress of the arts and of trade, the abundant yield of the land-through everything, in fact, which makes the citizens better and happier. Hereby, then, it lies in the power of a ruler to benefit every class in the State, and amongst the rest to promote to the utmost the interests of the poor; and this in virtue of his office, and without being open to suspicion of undue interference - since it is the province of the commonwealth to serve the common good. And the more that is done for the benefit of the working classes by the general laws of the country, the less need will there be to seek for special means to relieve them.
