From Pope St. John Paul II’s encyclical Fides et Ratio (1984):
Inseparable as they are from people and their history, cultures share the dynamics which the human experience of life reveals. They change and advance because people meet in new ways and share with each other their ways of life. Cultures are fed by the communication of values, and they survive and flourish insofar as they remain open to assimilating new experiences. How are we to explain these dynamics? All people are part of a culture, depend upon it and shape it. Human beings are both child and parent of the culture in which they are immersed. To everything they do, they bring something which sets them apart from the rest of creation: their unfailing openness to mystery and their boundless desire for knowledge. Lying deep in every culture, there appears this impulse towards a fulfilment. We may say, then, that culture itself has an intrinsic capacity to receive divine Revelation.
Cultural context permeates the living of Christian faith, which contributes in turn little by little to shaping that context. To every culture Christians bring the unchanging truth of God, which he reveals in the history and culture of a people. Time and again, therefore, in the course of the centuries we have seen repeated the event witnessed by the pilgrims in Jerusalem on the day of Pentecost. Hearing the Apostles, they asked one another: “Are not all these who are speaking Galileans? And how is it that we hear, each of us in his own native language? Parthians and Medes and Elamites and residents of Mesopotamia, Judea and Cappadocia, Pontus and Asia, Phrygia and Pamphylia, Egypt and the parts of Libya belonging to Cyrene, and visitors from Rome, both Jews and proselytes, Cretans and Arabians, we hear them telling in our own tongues the mighty works of God” (Acts 2:7-11). While it demands of all who hear it the adherence of faith, the proclamation of the Gospel in different cultures allows people to preserve their own cultural identity. This in no way creates division, because the community of the baptized is marked by a universality which can embrace every culture and help to foster whatever is implicit in them to the point where it will be fully explicit in the light of truth.
This means that no one culture can ever become the criterion of judgment, much less the ultimate criterion of truth with regard to God’s Revelation. The Gospel is not opposed to any culture, as if in engaging a culture the Gospel would seek to strip it of its native riches and force it to adopt forms which are alien to it. On the contrary, the message which believers bring to the world and to cultures is a genuine liberation from all the disorders caused by sin and is, at the same time, a call to the fullness of truth. Cultures are not only not diminished by this encounter; rather, they are prompted to open themselves to the newness of the Gospel’s truth and to be stirred by this truth to develop in new ways.
