INTRODUCTION

1. The Lord Jesus, before ascending into heaven, commanded his disciples to proclaim the Gospel to the whole world and to baptize all nations: "Go into the whole world and proclaim the Gospel to every creature. He who believes and is baptized will be saved; he who does not believe will be condemned" (Mk 16:15-16); "All power in heaven and on earth has been given to me. Go therefore and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Spirit, teaching them to observe all that I have commanded you. And behold, I am with you always, until the end of the world" (Mt 28:18-20; cf. Lk 24:46-48; Jn 17:18,20,21; Acts 1:8).

The Church's universal mission is born from the command of Jesus Christ and is fulfilled in the course of the centuries in the proclamation of the mystery of God, Father, Son, and Holy Spirit, and the mystery of the incarnation of the Son, as saving event for all humanity. The fundamental contents of the profession of the Christian faith are expressed thus: "I believe in one God, the Father, Almighty, maker of heaven and earth, of all that is, seen and unseen. I believe in one Lord, Jesus Christ, the only Son of God, eternally begotten of the Father, God from God, Light from Light, true God from true God, begotten, not made, of one being with the Father. Through him all things were made. For us men and for our salvation, he came down from heaven: by the power of the Holy Spirit he became incarnate of the Virgin Mary, and became man. For our sake he was crucified under Pontius Pilate; he suffered death and was buried. On the third day he rose again in accordance with the Scriptures; he ascended into heaven and is seated at the right hand of the Father. He will come again in glory to judge the living and the dead, and his kingdom will have no end. I believe in the Holy Spirit, the Lord, the giver of life, who proceeds from the Father. With the Father and the Son he is worshipped and glorified. He has spoken through the prophets. I believe in one holy catholic and apostolic Church. I acknowledge one baptism for the forgiveness of sins. I look for the resurrection of the dead, and the life of the world to come".¹

2. In the course of the centuries, the Church has proclaimed and witnessed with fidelity to the Gospel of Jesus. At the close of the second millennium, however, this mission is still far from complete.² For that reason, Saint Paul's words are now more relevant than ever: "Preaching the Gospel is not a reason for me to boast; it is a necessity laid on me: woe to me if I do not preach the Gospel!" (1 Cor 9:16). This explains the Magisterium's particular attention to giving reasons for and supporting the evangelizing mission of the Church, above all in connection with the religious traditions of the world.³

In considering the values which these religions witness to and offer humanity, with an open and positive approach, the Second Vatican Council's Declaration on the relation of the Church to non-Christian religions states: "The Catholic Church rejects nothing of what is true and holy in these religions. She has a high regard for the manner of life and conduct, the precepts and teachings, which, although differing in many ways from her own teaching, nonetheless often reflect a ray of that truth which enlightens all men".⁴ Continuing in this line of thought, the Church's proclamation of Jesus Christ, "the way, the truth, and the life" (Jn 14:6), today also makes use of the practice of inter-religious dialogue. Such dialogue certainly does not replace, but rather accompanies the missio ad gentes, directed toward that "mystery of unity", from which "it follows that all men and women who are saved share, though differently, in the same mystery of salvation in Jesus Christ through his Spirit".⁵ Inter-religious dialogue, which is part of the Church's evangelizing mission,⁶ requires an attitude of understanding and a relationship of mutual knowledge and reciprocal enrichment, in obedience to the truth and with respect for freedom.⁷

3. In the practice of dialogue between the Christian faith and other religious traditions, as well as in seeking to understand its theoretical basis more deeply, new questions arise that need to be addressed through pursuing new paths of research, advancing proposals, and suggesting ways of acting that call for attentive discernment. In this task, the present Declaration seeks to recall to Bishops, theologians, and all the Catholic faithful, certain indispensable elements of Christian doctrine, which may help theological reflection in developing solutions consistent with the contents of the faith and responsive to the pressing needs of contemporary culture.

The expository language of the Declaration corresponds to its purpose, which is not to treat in a systematic manner the question of the unicity and salvific universality of the mystery of Jesus Christ and the Church, nor to propose solutions to questions that are matters of free theological debate, but rather to set forth again the doctrine of the Catholic faith in these areas, pointing out some fundamental questions that remain open to further development, and refuting specific positions that are erroneous or ambiguous. For this reason, the Declaration takes up what has been taught in previous Magisterial documents, in order to reiterate certain truths that are part of the Church's faith.

4. The Church's constant missionary proclamation is endangered today by relativistic theories which seek to justify religious pluralism, not only de facto but also de iure (or in principle). As a consequence, it is held that certain truths have been superseded; for example, the definitive and complete character of the revelation of Jesus Christ, the nature of Christian faith as compared with that of belief in other religions, the inspired nature of the books of Sacred Scripture, the personal unity between the Eternal Word and Jesus of Nazareth, the unity of the economy of the Incarnate Word and the Holy Spirit, the unicity and salvific universality of the mystery of Jesus Christ, the universal salvific mediation of the Church, the inseparability — while recognizing the distinction — of the kingdom of God, the kingdom of Christ, and the Church, and the subsistence of the one Church of Christ in the Catholic Church.

The roots of these problems are to be found in certain presuppositions of both a philosophical and theological nature, which hinder the understanding and acceptance of the revealed truth. Some of these can be mentioned: the conviction of the elusiveness and inexpressibility of divine truth, even by Christian revelation; relativistic attitudes toward truth itself, according to which what is true for some would not be true for others; the radical opposition posited between the logical mentality of the West and the symbolic mentality of the East; the subjectivism which, by regarding reason as the only source of knowledge, becomes incapable of raising its "gaze to the heights, not daring to rise to the truth of being";⁸ the difficulty in understanding and accepting the presence of definitive and eschatological events in history; the metaphysical emptying of the historical incarnation of the Eternal Logos, reduced to a mere appearing of God in history; the eclecticism of those who, in theological research, uncritically absorb ideas from a variety of philosophical and theological contexts without regard for consistency, systematic connection, or compatibility with Christian truth; finally, the tendency to read and to interpret Sacred Scripture outside the Tradition and Magisterium of the Church.

On the basis of such presuppositions, which may evince different nuances, certain theological proposals are developed — at times presented as assertions, and at times as hypotheses — in which Christian revelation and the mystery of Jesus Christ and the Church lose their character of absolute truth and salvific universality, or at least shadows of doubt and uncertainty are cast upon them.
