Redemptoris Missio: On the Permanent Validity of the Church's Missionary Mandate
56 Dialogue does not originate from tactical concerns or self-interest, but is an activity with its own guiding principles, requirements and dignity. It is demanded by deep respect for everything that has been brought about in human beings by the Spirit who blows where he wills. Through dialogue, the Church seeks to uncover the "seeds of the Word," a "ray of that truth which enlightens all men''; these are found in individuals and in the religious traditions of mankind. Dialogue is based on hope and love, and will bear fruit in the Spirit. Other religions constitute a positive challenge for the Church: they stimulate her both to discover and acknowledge the signs of Christ's presence and of the working of the Spirit, as well as to examine more deeply her own identity and to bear witness to the fullness of Revelation which she has received for the good of all. This gives rise to the spirit which must enliven dialogue in the context of mission. Those engaged in this dialogue must be consistent with their own religious traditions and convictions, and be open to understanding those of the other party without pretense or close-mindedness, but with truth, humility and frankness, knowing that dialogue can enrich each side. There must be no abandonment of principles nor false irenicism, but instead a witness given and received for mutual advancement on the road of religious inquiry and experience, and at the same time for the elimination of prejudice, intolerance and misunderstandings. Dialogue leads to inner purification and conversion which, if pursued with docility to the Holy Spirit, will be spiritually fruitful.
