Within this larger human world the multiple spiritual and humanist traditions implicate each other, and evoke from each other higher developments of which each is capable. These traditions implicate each other for each has a universal mission to humanity. Each is pan-human in its significance.
None can be truly itself without the others.
Each has a distinctive contribution to human development that can be made only by itself. Each must therefore be kept distinctive even as it reaches a universal diffusion among all peoples. For any tradition to withhold itself from the other societies of humanity or for any to exclude the other traditions is to vitiate and stultify its own tradition and its own developments, to condemn itself to sterile isolation from the only forces that can in these times give it life and creativity. All human traditions are dimensions of each other. If as Christians we assert the Christian dimension of the entire world, we must not refuse to be a dimension of the Hindu world, of the Buddhist world, of the Islamic world.
