Toward this visionary paradigm, the ecclesiological basis has a crucial task. As sacrament the Church is the sign and instrument for the coming unity of humankind. In this respect, an adequate ecclesiology has to present the Church as the Church for others. The Church's existence must reveal the Kingdom of God, not only as the fulfillment of the Church but also as the future of the world. This vision is not so far above; if theology is considered as a science through which God becomes comprehensible and accessible to people of all cultural and religious backgrounds. Thus, the author creates a new paradigm for Christian Mission which could be stated in the words of Pope Benedict, As Christians we should never limit ourselves to asking how I can save myself. We should also ask: what can I do in order that the others may be saved and that for them too the star of hope may rise? Then I shall have done my utmost for my personal salvation as well3. This paradigm applies not merely to an individual Christian but to all churches that are engrossed in preserving their identity and their 'narrow' missions
