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. “The child belongs to the father,” and is, as it were, the continuation of the father’s personality; and speaking strictly, the child takes its place in civil society, not of its own right, but in its quality as member of the family in which it is born. And for the very reason that “the child belongs to the father” it is, as St. Thomas Aquinas says, “before it attains the use of free will, under the power and the charge of its parents.” The socialists, therefore, in setting aside the parent and setting up a State supervision, act against natural justice, and destroy the structure of the home.
And in addition to injustice, it is only too evident what an upset and disturbance there would be in all classes, and to how intolerable and hateful a slavery citizens would be subjected. The door would be thrown open to envy, to mutual invective, and to discord; the sources of wealth themselves would run dry, for no one would have any interest in exerting his talents or his industry; and that ideal equality about which they entertain pleasant dreams would be in reality the levelling down of all to a like condition of misery and degradation. Hence, it is clear that the main tenet of socialism, community of goods, must be utterly rejected, since it only injures those whom it would seem meant to benefit, is directly contrary to the natural rights of mankind, and would introduce confusion and disorder into the commonweal. The first and most fundamental principle, therefore, if one would undertake to alleviate the condition of the masses, must be the inviolability of private property. This being established, we proceed to show where the remedy sought for must be found. — from Rerum Novarum (1891)
