Centesimus Annus: On the Hundredth Anniversary of Rerum Novarum
30 In Rerum novarum, Leo XIII strongly affirmed the natural character of the right to private property, using various arguments against the socialism of his time. This right, which is fundamental for the autonomy and development of the person, has always been defended by the Church up to our own day. At the same time, the Church teaches that the possession of material goods is not an absolute right, and that its limits are inscribed in its very nature as a human right. While the Pope proclaimed the right to private ownership, he affirmed with equal clarity that the "use" of goods, while marked by freedom, is subordinated to their original common destination as created goods, as well as to the will of Jesus Christ as expressed in the Gospel. Pope Leo wrote: "those whom fortune favours are admonished ... that they should tremble at the warnings of Jesus Christ ... and that a most strict account must be given to the Supreme Judge for the use of all they possess"; and quoting Saint Thomas Aquinas, he added: "But if the question be asked, how must one's possessions be used? the Church replies without hesitation that man should not consider his material possessions as his own, but as common to all...", because "above the laws and judgments of men stands the law, the judgment of Christ". The Successors of Leo XIII have repeated this twofold affirmation: the necessity and therefore the legitimacy of private ownership, as well as the limits which are imposed on it. The Second Vatican Council likewise clearly restated the traditional doctrine in words which bear repeating: "In making use of the exterior things we lawfully possess, we ought to regard them not just as our own but also as common, in the sense that they can profit not only the owners but others too"; and a little later we read: "Private property or some ownership of external goods affords each person the scope needed for personal and family autonomy, and should be regarded as an extension of human freedom ... Of its nature private property also has a social function which is based on the law of the common purpose of goods ". I have returned to this same doctrine, first in my address to the Third Conference of the Latin American Bishops at Puebla, and later in the Encyclicals Laborem exercens and Sollicitudo rei socialis.
