a. Origin and meaning
171. Among the numerous implications of the common good, immediate significance is taken on by the principle of the universal destination of goods: “God destined the earth and all it contains for all men and all peoples so that all created things would be shared fairly by all mankind under the guidance of justice tempered by charity”. This principle is based on the fact that “the original source of all that is good is the very act of God, who created both the earth and man, and who gave the earth to man so that he might have dominion over it by his work and enjoy its fruits (Gen 1:28-29). God gave the earth to the whole human race for the sustenance of all its members, without excluding or favouring anyone.
This is the foundation of the universal destination of the earth's goods. The earth, by reason of its fruitfulness and its capacity to satisfy human needs, is God's first gift for the sustenance of human life”. The human person cannot do without the material goods that correspond to his primary needs and constitute the basic conditions for his existence; these goods are absolutely indispensable if he is to feed himself, grow, communicate, associate with others, and attain the highest purposes to which he is called.
172. The universal right to use the goods of the earth is based on the principle of the universal destination of goods. Each person must have access to the level of well-being necessary for his full development. The right to the common use of goods is the “first principle of the whole ethical and social order”  and “the characteristic principle of Christian social doctrine”. For this reason the Church feels bound in duty to specify the nature and characteristics of this principle. It is first of all a natural right, inscribed in human nature and not merely a positive right connected with changing historical circumstances; moreover it is an “inherent”  right. It is innate in individual persons, in every person, and has priority with regard to any human intervention concerning goods, to any legal system concerning the same, to any economic or social system or method: “All other rights, whatever they are, including property rights and the right of free trade must be subordinated to this norm [the universal destination of goods]; they must not hinder it, but must rather expedite its application. It must be considered a serious and urgent social obligation to refer these rights to their original purpose”.
173. Putting the principal of the universal destination of goods into concrete practice, according to the different cultural and social contexts, means that methods, limits and objects must be precisely defined. Universal destination and utilization of goods do not mean that everything is at the disposal of each person or of all people, or that the same object may be useful or belong to each person or all people. If it is true that everyone is born with the right to use the goods of the earth, it is likewise true that, in order to ensure that this right is exercised in an equitable and orderly fashion, regulated interventions are necessary, interventions that are the result of national and international agreements, and a juridical order that adjudicates and specifies the exercise of this right.
174. The principle of the universal destination of goods is an invitation to develop an economic vision inspired by moral values that permit people not to lose sight of the origin or purpose of these goods, so as to bring about a world of fairness and solidarity, in which the creation of wealth can take on a positive function. Wealth, in effect, presents this possibility in the many different forms in which it can find expression as the result of a process of production that works with the available technological and economic resources, both natural and derived. This result is guided by resourcefulness, planning and labour, and used as a means for promoting the well-being of all men and all peoples and for preventing their exclusion and exploitation.
175. The universal destination of goods requires a common effort to obtain for every person and for all peoples the conditions necessary for integral development, so that everyone can contribute to making a more humane world, “in which each individual can give and receive, and in which the progress of some will no longer be an obstacle to the development of others, nor a pretext for their enslavement”. This principle corresponds to the call made unceasingly by the Gospel to people and societies of all times, tempted as they always are by the desire to possess, temptations which the Lord Jesus chose to undergo (cf. Mk 1:12-13; Mt4:1-11; Lk 4:1-13) in order to teach us how to overcome them with his grace.
b. The universal destination of goods and private property
176. By means of work and making use of the gift of intelligence, people are able to exercise dominion over the earth and make it a fitting home: “In this way, he makes part of the earth his own, precisely the part which he has acquired through work; this is the origin of individual property”. Private property and other forms of private ownership of goods “assure a person a highly necessary sphere for the exercise of his personal and family autonomy and ought to be considered as an extension of human freedom ... stimulating exercise of responsibility, it constitutes one of the conditions for civil liberty”. Private property is an essential element of an authentically social and democratic economic policy, and it is the guarantee of a correct social order. The Church's social doctrine requires that ownership of goods be equally accessible to all, so that all may become, at least in some measure, owners, and it excludes recourse to forms of “common and promiscuous dominion”.
177. Christian tradition has never recognized the right to private property as absolute and untouchable: “On the contrary, it has always understood this right within the broader context of the right common to all to use the goods of the whole of creation: the right to private property is subordinated to the right to common use, to the fact that goods are meant for everyone”. The principle of the universal destination of goods is an affirmation both of God's full and perennial lordship over every reality and of the requirement that the goods of creation remain ever destined to the development of the whole person and of all humanity. This principle is not opposed to the right to private property but indicates the need to regulate it. Private property, in fact, regardless of the concrete forms of the regulations and juridical norms relative to it, is in its essence only an instrument for respecting the principle of the universal destination of goods; in the final analysis, therefore, it is not an end but a means.
178. The Church's social teaching moreover calls for recognition of the social function of any form of private ownership  that clearly refers to its necessary relation to the common good. Man “should regard the external things that he legitimately possesses not only as his own but also as common in the sense that they should be able to benefit not only him but also others”. The universal destination of goods entails obligations on how goods are to be used by their legitimate owners. Individual persons may not use their resources without considering the effects that this use will have, rather they must act in a way that benefits not only themselves and their family but also the common good. From this there arises the duty on the part of owners not to let the goods in their possession go idle and to channel them to productive activity, even entrusting them to others who are desirous and capable of putting them to use in production.
179. The present historical period has placed at the disposal of society new goods that were completely unknown until recent times. This calls for a fresh reading of the principle of the universal destination of the goods of the earth and makes it necessary to extend this principle so that it includes the latest developments brought about by economic and technological progress. The ownership of these new goods — the results of knowledge, technology and know-how — becomes ever more decisive, because “the wealth of the industrialized nations is based much more on this kind of ownership than on natural resources”.
New technological and scientific knowledge must be placed at the service of mankind's primary needs, gradually increasing humanity's common patrimony. Putting the principle of the universal destination of goods into full effect therefore requires action at the international level and planned programmes on the part of all countries. “It is necessary to break down the barriers and monopolies which leave so many countries on the margins of development, and to provide all individuals and nations with the basic conditions which will enable them to share in development”.
180. If forms of property unknown in the past take on significant importance in the process of economic and social development, nonetheless, traditional forms of property must not be forgotten. Individual property is not the only legitimate form of ownership. The ancient form of community property also has a particular importance; though it can be found in economically advanced countries, it is particularly characteristic of the social structure of many indigenous peoples. This is a form of property that has such a profound impact on the economic, cultural and political life of those peoples that it constitutes a fundamental element of their survival and well-being. The defence and appreciation of community property must not exclude, however, an awareness of the fact that this type of property also is destined to evolve. If actions were taken only to preserve its present form, there would be the risk of tying it to the past and in this way compromising it.
An equitable distribution of land remains ever critical, especially in developing countries and in countries that have recently changed from systems based on collectivities or colonization. In rural areas, the possibility of acquiring land through opportunities offered by labour and credit markets is a necessary condition for access to other goods and services. Besides constituting an effective means for safeguarding the environment, this possibility represents a system of social security that can be put in place also in those countries with a weak administrative structure.
181. To the subjects, whether individuals or communities, that exercise ownership of various types of property accrue a series of objective advantages: better living conditions, security for the future, and a greater number of options from which to choose. On the other hand, property may also bring a series of deceptive promises that are a source of temptation. Those people and societies that go so far as to absolutize the role of property end up experiencing the bitterest type of slavery. In fact, there is no category of possession that can be considered indifferent with regard to the influence that it may have both on individuals and on institutions. Owners who heedlessly idolize their goods (cf. Mt 6:24, 19:21-26; Lk 16:13) become owned and enslaved by them. Only by recognizing that these goods are dependent on God the Creator and then directing their use to the common good, is it possible to give material goods their proper function as useful tools for the growth of individuals and peoples.
c. The universal destination of goods and the preferential option for the poor
182. The principle of the universal destination of goods requires that the poor, the marginalized and in all cases those whose living conditions interfere with their proper growth should be the focus of particular concern. To this end, the preferential option for the poor should be reaffirmed in all its force. “This is an option, or a special form of primacy in the exercise of Christian charity, to which the whole tradition of the Church bears witness. It affects the life of each Christian inasmuch as he or she seeks to imitate the life of Christ, but it applies equally to our social responsibilities and hence to our manner of living, and to the logical decisions to be made concerning the ownership and use of goods. Today, furthermore, given the worldwide dimension which the social question has assumed, this love of preference for the poor, and the decisions which it inspires in us, cannot but embrace the immense multitudes of the hungry, the needy, the homeless, those without health care and, above all, those without hope of a better future”.
183. Human misery is a clear sign of man's natural condition of frailty and of his need for salvation. Christ the Saviour showed compassion in this regard, identifying himself with the “least” among men (cf. Mt 25:40,45). “It is by what they have done for the poor that Jesus Christ will recognize his chosen ones. When ‘the poor have the good news preached to them' (Mt 11:5), it is a sign of Christ's presence”.
Jesus says: “You always have the poor with you, but you will not always have me” (Mt 26:11; cf. Mk 14:7; Jn 12:8). He makes this statement not to contrast the attention due to him with service of the poor. Christian realism, while appreciating on the one hand the praiseworthy efforts being made to defeat poverty, is cautious on the other hand regarding ideological positions and Messianistic beliefs that sustain the illusion that it is possible to eliminate the problem of poverty completely from this world. This will happen only upon Christ's return, when he will be with us once more, for ever. In the meantime, the poor remain entrusted to us and it is this responsibility upon which we shall be judged at the end of time (cf. Mt 25:31-46): “Our Lord warns us that we shall be separated from him if we fail to meet the serious needs of the poor and the little ones who are his brethren”.
184. The Church's love for the poor is inspired by the Gospel of the Beatitudes, by the poverty of Jesus and by his attention to the poor. This love concerns material poverty and also the numerous forms of cultural and religious poverty. The Church, “since her origin and in spite of the failing of many of her members, has not ceased to work for their relief, defence and liberation through numerous works of charity which remain indispensable always and everywhere”. Prompted by the Gospel injunction, “You have received without paying, give without pay” (Mt 10:8), the Church teaches that one should assist one's fellow man in his various needs and fills the human community with countless works of corporal and spiritual mercy. “Among all these, giving alms to the poor is one of the chief witnesses to fraternal charity: it is also a work of justice pleasing to God”, even if the practice of charity is not limited to alms-giving but implies addressing the social and political dimensions of the problem of poverty. In her teaching the Church constantly returns to this relationship between charity and justice: “When we attend to the needs of those in want, we give them what is theirs, not ours. More than performing works of mercy, we are paying a debt of justice”. The Council Fathers strongly recommended that this duty be fulfilled correctly, remembering that “what is already due in justice is not to be offered as a gift of charity”. Love for the poor is certainly “incompatible with immoderate love of riches or their selfish use”  (cf. Jas 5:1-6).
