1. Charity in truth, to which Jesus Christ bore witness by his earthly life and especially by his death and resurrection, is the principal driving force behind the authentic development of every person and of all humanity. Love — caritas — is an extraordinary force which leads people to opt for courageous and generous engagement in the field of justice and peace. It is a force that has its origin in God, Eternal Love and Absolute Truth. Each person finds his good by adherence to God's plan for him, in order to realize it fully: in this plan, he finds his truth, and through adherence to this truth he becomes free (cf. Jn 8:22). To defend the truth, to articulate it with humility and conviction, and to bear witness to it in life are therefore exacting and indispensable forms of charity. Charity, in fact, “rejoices in the truth” (1 Cor 13:6). All people feel the interior impulse to love authentically: love and truth never abandon them completely, because these are the vocation planted by God in the heart and mind of every human person. The search for love and truth is purified and liberated by Jesus Christ from the impoverishment that our humanity brings to it, and he reveals to us in all its fullness the initiative of love and the plan for true life that God has prepared for us. In Christ, charity in truth becomes the Face of his Person, a vocation for us to love our brothers and sisters in the truth of his plan. Indeed, he himself is the Truth (cf. Jn 14:6).
2. Charity is at the heart of the Church's social doctrine. Every responsibility and every commitment spelt out by that doctrine is derived from charity which, according to the teaching of Jesus, is the synthesis of the entire Law (cf. Mt 22:36- 40). It gives real substance to the personal relationship with God and with neighbour; it is the principle not only of micro-relationships (with friends, with family members or within small groups) but also of macro-relationships (social, economic and political ones). For the Church, instructed by the Gospel, charity is everything because, as Saint John teaches (cf. 1 Jn 4:8, 16) and as I recalled in my first Encyclical Letter, “God is love” (Deus Caritas Est): everything has its origin in God's love, everything is shaped by it, everything is directed towards it. Love is God's greatest gift to humanity, it is his promise and our hope.
I am aware of the ways in which charity has been and continues to be misconstrued and emptied of meaning, with the consequent risk of being misinterpreted, detached from ethical living and, in any event, undervalued. In the social, juridical, cultural, political and economic fields — the contexts, in other words, that are most exposed to this danger — it is easily dismissed as irrelevant for interpreting and giving direction to moral responsibility. Hence the need to link charity with truth not only in the sequence, pointed out by Saint Paul, of veritas in caritate (Eph 4:15), but also in the inverse and complementary sequence of caritas in veritate. Truth needs to be sought, found and expressed within the “economy” of charity, but charity in its turn needs to be understood, confirmed and practised in the light of truth. In this way, not only do we do a service to charity enlightened by truth, but we also help give credibility to truth, demonstrating its persuasive and authenticating power in the practical setting of social living. This is a matter of no small account today, in a social and cultural context which relativizes truth, often paying little heed to it and showing increasing reluctance to acknowledge its existence.
3. Through this close link with truth, charity can be recognized as an authentic expression of humanity and as an element of fundamental importance in human relations, including those of a public nature. Only in truth does charity shine forth, only in truth can charity be authentically lived. Truth is the light that gives meaning and value to charity. That light is both the light of reason and the light of faith, through which the intellect attains to the natural and supernatural truth of charity: it grasps its meaning as gift, acceptance, and communion. Without truth, charity degenerates into sentimentality. Love becomes an empty shell, to be filled in an arbitrary way. In a culture without truth, this is the fatal risk facing love. It falls prey to contingent subjective emotions and opinions, the word “love” is abused and distorted, to the point where it comes to mean the opposite. Truth frees charity from the constraints of an emotionalism that deprives it of relational and social content, and of a fideism that deprives it of human and universal breathing-space. In the truth, charity reflects the personal yet public dimension of faith in the God of the Bible, who is both Agápe and Lógos: Charity and Truth, Love and Word.
4. Because it is filled with truth, charity can be understood in the abundance of its values, it can be shared and communicated. Truth, in fact, is lógos which creates diá-logos, and hence communication and communion. Truth, by enabling men and women to let go of their subjective opinions and impressions, allows them to move beyond cultural and historical limitations and to come together in the assessment of the value and substance of things. Truth opens and unites our minds in the lógos of love: this is the Christian proclamation and testimony of charity. In the present social and cultural context, where there is a widespread tendency to relativize truth, practising charity in truth helps people to understand that adhering to the values of Christianity is not merely useful but essential for building a good society and for true integral human development. A Christianity of charity without truth would be more or less interchangeable with a pool of good sentiments, helpful for social cohesion, but of little relevance. [I like to call this phenonomenon the reduction of Christianity to just another "Peace Corps."] In other words, there would no longer be any real place for God in the world. Without truth, charity is confined to a narrow field devoid of relations. It is excluded from the plans and processes of promoting human development of universal range, in dialogue between knowledge and praxis.
5. Charity is love received and given. It is “grace” (cháris). Its source is the wellspring of the Father's love for the Son, in the Holy Spirit. Love comes down to us from the Son. It is creative love, through which we have our being; it is redemptive love, through which we are recreated. Love is revealed and made present by Christ (cf. Jn 13:1) and “poured into our hearts through the Holy Spirit” (Rom 5:5). [Here is the charismatic dimension that is unavoidable in all complete Christian proclamation.] As the objects of God's love, men and women become subjects of charity, they are called to make themselves instruments of grace, so as to pour forth God's charity and to weave networks of charity.
This dynamic of charity received and given is what gives rise to the Church's social teaching, which is caritas in veritate in re sociali: the proclamation of the truth of Christ's love in society. This doctrine is a service to charity, but its locus is truth. Truth preserves and expresses charity's power to liberate in the ever-changing events of history. It is at the same time the truth of faith and of reason, both in the distinction and also in the convergence of those two cognitive fields. Development, social well-being, the search for a satisfactory solution to the grave socio-economic problems besetting humanity, all need this truth. What they need even more is that this truth should be loved and demonstrated. Without truth, without trust and love for what is true, there is no social conscience and responsibility, and social action ends up serving private interests and the logic of power, resulting in social fragmentation, especially in a globalized society at difficult times like the present.
6. “Caritas in veritate” is the principle around which the Church's social doctrine turns, a principle that takes on practical form in the criteria that govern moral action. I would like to consider two of these in particular, of special relevance to the commitment to development in an increasingly globalized society: justice and the common good.
First of all, justice. Ubi societas, ibi ius: every society draws up its own system of justice. Charity goes beyond justice, because to love is to give, to offer what is “mine” to the other; but it never lacks justice, which prompts us to give the other what is “his”, what is due to him by reason of his being or his acting. I cannot “give” what is mine to the other, without first giving him what pertains to him in justice. If we love others with charity, then first of all we are just towards them. Not only is justice not extraneous to charity, not only is it not an alternative or parallel path to charity: justice is inseparable from charity, and intrinsic to it. Justice is the primary way of charity or, in Paul VI's words, “the minimum measure” of it, an integral part of the love “in deed and in truth” (1 Jn 3:18), to which Saint John exhorts us. On the one hand, charity demands justice: recognition and respect for the legitimate rights of individuals and peoples. It strives to build the earthly city according to law and justice. On the other hand, charity transcends justice and completes it in the logic of giving and forgiving. The earthly city is promoted not merely by relationships of rights and duties, but to an even greater and more fundamental extent by relationships of gratuitousness, mercy and communion. Charity always manifests God's love in human relationships as well, it gives theological and salvific value to all commitment for justice in the world.
7. Another important consideration is the common good. To love someone is to desire that person's good and to take effective steps to secure it. Besides the good of the individual, there is a good that is linked to living in society: the common good. It is the good of “all of us”, made up of individuals, families and intermediate groups who together constitute society. It is a good that is sought not for its own sake, but for the people who belong to the social community and who can only really and effectively pursue their good within it. To desire the common good and strive towards it is a requirement of justice and charity. To take a stand for the common good is on the one hand to be solicitous for, and on the other hand to avail oneself of, that complex of institutions that give structure to the life of society, juridically, civilly, politically and culturally, making it the pólis, or “city”. The more we strive to secure a common good corresponding to the real needs of our neighbours, the more effectively we love them. Every Christian is called to practise this charity, in a manner corresponding to his vocation and according to the degree of influence he wields in the pólis. This is the institutional path — we might also call it the political path — of charity, no less excellent and effective than the kind of charity which encounters the neighbour directly, outside the institutional mediation of the pólis. When animated by charity, commitment to the common good has greater worth than a merely secular and political stand would have. Like all commitment to justice, it has a place within the testimony of divine charity that paves the way for eternity through temporal action. Man's earthly activity, when inspired and sustained by charity, contributes to the building of the universal city of God, which is the goal of the history of the human family. In an increasingly globalized society, the common good and the effort to obtain it cannot fail to assume the dimensions of the whole human family, that is to say, the community of peoples and nations, in such a way as to shape the earthly city in unity and peace, rendering it to some degree an anticipation and a prefiguration of the undivided city of God.
8. In 1967, when he issued the Encyclical Populorum Progressio, my venerable predecessor Pope Paul VI illuminated the great theme of the development of peoples with the splendour of truth and the gentle light of Christ's charity. He taught that life in Christ is the first and principal factor of development and he entrusted us with the task of travelling the path of development with all our heart and all our intelligence, that is to say with the ardour of charity and the wisdom of truth. It is the primordial truth of God's love, grace bestowed upon us, that opens our lives to gift and makes it possible to hope for a “development of the whole man and of all men”, to hope for progress “from less human conditions to those which are more human”, obtained by overcoming the difficulties that are inevitably encountered along the way.
At a distance of over forty years from the Encyclical's publication, I intend to pay tribute and to honour the memory of the great Pope Paul VI, revisiting his teachings on integral human development and taking my place within the path that they marked out, so as to apply them to the present moment. This continual application to contemporary circumstances began with the Encyclical Sollicitudo Rei Socialis, with which the Servant of God Pope John Paul II chose to mark the twentieth anniversary of the publication of Populorum Progressio. Until that time, only Rerum Novarum had been commemorated in this way. Now that a further twenty years have passed, I express my conviction that Populorum Progressio deserves to be considered “the Rerum Novarum of the present age”, shedding light upon humanity's journey towards unity.
[These words are an enthusiastic tribute to Pope Paul VI. How ironic that you sometimes hear those who consider themselves quite orthodox take potshots at Paul VI.]9. Love in truth — caritas in veritate — is a great challenge for the Church in a world that is becoming progressively and pervasively globalized. The risk for our time is that the de facto interdependence of people and nations is not matched by ethical interaction of consciences and minds that would give rise to truly human development. Only in charity, illumined by the light of reason and faith, is it possible to pursue development goals that possess a more humane and humanizing value. The sharing of goods and resources, from which authentic development proceeds, is not guaranteed by merely technical progress and relationships of utility, but by the potential of love that overcomes evil with good (cf. Rom 12:21), opening up the path towards reciprocity of consciences and liberties.
The Church does not have technical solutions to offer and does not claim “to interfere in any way in the politics of States.” She does, however, have a mission of truth to accomplish, in every time and circumstance, for a society that is attuned to man, to his dignity, to his vocation. Without truth, it is easy to fall into an empiricist and sceptical view of life, incapable of rising to the level of praxis because of a lack of interest in grasping the values — sometimes even the meanings — with which to judge and direct it. Fidelity to man requires fidelity to the truth, which alone is the guarantee of freedom (cf. Jn 8:32) and of the possibility of integral human development. For this reason the Church searches for truth, proclaims it tirelessly and recognizes it wherever it is manifested. This mission of truth is something that the Church can never renounce. Her social doctrine is a particular dimension of this proclamation: it is a service to the truth which sets us free. Open to the truth, from whichever branch of knowledge it comes, the Church's social doctrine receives it, assembles into a unity the fragments in which it is often found, and mediates it within the constantly changing life-patterns of the society of peoples and nations.
