101 A survey of the history of thought, especially in the West, shows clearly that the encounter between philosophy and theology and the exchange of their respective insights have contributed richly to the progress of humanity. Endowed as it is with an openness and originality which allow it to stand as the science of faith, theology has certainly challenged reason to remain open to the radical newness found in God's Revelation; and this has been an undoubted boon for philosophy which has thus glimpsed new vistas of further meanings which reason is summoned to penetrate. Precisely in the light of this consideration, and just as I have reaffirmed theology's duty to recover its true relationship with philosophy, I feel equally bound to stress how right it is that, for the benefit and development of human thought, philosophy too should recover its relationship with theology. In theology, philosophy will find not the thinking of a single person which, however rich and profound, still entails the limited perspective of an individual, but the wealth of a communal reflection. For by its very nature, theology is sustained in the search for truth by its ecclesial context and by the tradition of the People of God, with its harmony of many different fields of learning and culture within the unity of faith.
