From Pope St. John Paul II’s encyclical Fides et Ratio (1984):
Insisting on the importance and true range of philosophical thought, the Church promotes both the defence of human dignity and the proclamation of the Gospel message. There is today no more urgent preparation for the performance of these tasks than this: to lead people to discover both their capacity to know the truth124 and their yearning for the ultimate and definitive meaning of life. In the light of these profound needs, inscribed by God in human nature, the human and humanizing meaning of God’s word also emerges more clearly. Through the mediation of a philosophy which is also true wisdom, people today will come to realize that their humanity is all the more affirmed the more they entrust themselves to the Gospel and open themselves to Christ.
Philosophy moreover is the mirror which reflects the culture of a people. A philosophy which responds to the challenge of theology’s demands and evolves in harmony with faith is part of that “evangelization of culture” which Paul VI proposed as one of the fundamental goals of evangelization.125 I have unstintingly recalled the pressing need for a new evangelization; and I appeal now to philosophers to explore more comprehensively the dimensions of the true, the good and the beautiful to which the word of God gives access. This task becomes all the more urgent if we consider the challenges which the new millennium seems to entail, and which affect in a particular way regions and cultures which have a long-standing Christian tradition. This attention to philosophy too should be seen as a fundamental and original contribution in service of the new evangelization.
