Fides et Ratio §35

It is this duality alone which allows us to specify correctly the relationship between revealed truth and philosophical learning. First, then, let us consider the links between faith and philosophy in the course of history. From this, certain principles will emerge as useful reference-points in the attempt to establish the correct link between the two orders of knowledge.
