From Pope St. John Paul II’s encyclical Fides et Ratio (1984):
Sacred Scripture indicates with remarkably clear cues how deeply related are the knowledge conferred by faith and the knowledge conferred by reason; and it is in the Wisdom literature that this relationship is addressed most explicitly. What is striking about these biblical texts, if they are read without prejudice, is that they embody not only the faith of Israel, but also the treasury of cultures and civilizations which have long vanished. As if by special design, the voices of Egypt and Mesopotamia sound again and certain features common to the cultures of the ancient Near East come to life in these pages which are so singularly rich in deep intuition.
It is no accident that, when the sacred author comes to describe the wise man, he portrays him as one who loves and seeks the truth: “Happy the man who meditates on wisdom and reasons intelligently, who reflects in his heart on her ways and ponders her secrets. He pursues her like a hunter and lies in wait on her paths. He peers through her windows and listens at her doors. He camps near her house and fastens his tent-peg to her walls; he pitches his tent near her and so finds an excellent resting-place; he places his children under her protection and lodges under her boughs; by her he is sheltered from the heat and he dwells in the shade of her glory” (Sir 14:20-27).
For the inspired writer, as we see, the desire for knowledge is characteristic of all people. Intelligence enables everyone, believer and non-believer, to reach “the deep waters” of knowledge (cf. Prov 20:5). It is true that ancient Israel did not come to knowledge of the world and its phenomena by way of abstraction, as did the Greek philosopher or the Egyptian sage. Still less did the good Israelite understand knowledge in the way of the modern world which tends more to distinguish different kinds of knowing. Nonetheless, the biblical world has made its own distinctive contribution to the theory of knowledge.
What is distinctive in the biblical text is the conviction that there is a profound and indissoluble unity between the knowledge of reason and the knowledge of faith. The world and all that happens within it, including history and the fate of peoples, are realities to be observed, analysed and assessed with all the resources of reason, but without faith ever being foreign to the process. Faith intervenes not to abolish reason’s autonomy nor to reduce its scope for action, but solely to bring the human being to understand that in these events it is the God of Israel who acts. Thus the world and the events of history cannot be understood in depth without professing faith in the God who is at work in them. Faith sharpens the inner eye, opening the mind to discover in the flux of events the workings of Providence. Here the words of the Book of Proverbs are pertinent: “The human mind plans the way, but the Lord directs the steps” (16:9). This is to say that with the light of reason human beings can know which path to take, but they can follow that path to its end, quickly and unhindered, only if with a rightly tuned spirit they search for it within the horizon of faith. Therefore, reason and faith cannot be separated without diminishing the capacity of men and women to know themselves, the world and God in an appropriate way.
