The article shows the interaction which exists between the practice of interreligious dialogue and a theology of religious pluralism. A first part develops the theological foundation of the dialogue: the common origin and destiny in God of all people; the universal presence of the Holy Spirit in the members of other religious traditions and in the traditions themselves; the universality of the Reign of God established in Jesus-Christ, of which the others are comembers with Christians and called to be cobuilders with them. The second part explains the challenge of dialogue: it requires from believers on both sides a personal commitment to one's own faith and an openness to the religious experience of the other; but the dialogue also bears common fruits, consisting in a mutual enrichment of the partners. Its aim is not the conversion of one to the faith of the other, but a deeper conversion of both towards God.
