From Pope St. John Paul II’s encyclical Fides et Ratio (1984):
To see this is to glimpse the solution of another problem: the problem of the enduring validity of the conceptual language used in Conciliar definitions. This is a question which my revered predecessor Pius XII addressed in his Encyclical Letter Humani Generis.112
This is a complex theme to ponder, since one must reckon seriously with the meaning which words assume in different times and cultures. Nonetheless, the history of thought shows that across the range of cultures and their development certain basic concepts retain their universal epistemological value and thus retain the truth of the propositions in which they are expressed. 113 Were this not the case, philosophy and the sciences could not communicate with each other, nor could they find a place in cultures different from those in which they were conceived and developed. The hermeneutical problem exists, to be sure; but it is not insoluble. Moreover, the objective value of many concepts does not exclude that their meaning is often imperfect. This is where philosophical speculation can be very helpful. We may hope, then, that philosophy will be especially concerned to deepen the understanding of the relationship between conceptual language and truth, and to propose ways which will lead to a right understanding of that relationship.
112 “It is clear that the Church cannot be tied to any and every passing philosophical system. Nevertheless, those notions and terms which have been developed though common effort by Catholic teachers over the course of the centuries to bring about some understanding of dogma are certainly not based on any such weak foundation. They are based on principles and notions deduced from a true knowledge of created things. In the process of deduction, this knowledge, like a star, gave enlightenment to the human mind through the Church. Hence it is not astonishing that some of these notions have not only been employed by the Ecumenical Councils, but even sanctioned by them, so that it is wrong to depart from them”: Encyclical Letter Humani Generis (12 August 1950): Acta Apostolicæ Sedis [AAS] 42 (1950), 566-567; cf. International Theological Commission, Document Interpretationis Problema (October 1989): Enchiridion Vaticanum 11, 2717-2811.
113 “As for the meaning of dogmatic formulas, this remains ever true and constant in the Church, even when it is expressed with greater clarity or more developed. The faithful therefore must shun the opinion, first, that dogmatic formulas (or some category of them) cannot signify the truth in a determinate way, but can only offer changeable approximations to it, which to a certain extent distort or alter it”: Sacred Congregation for the Doctrine of the Faith, Declaration in Defence of the Catholic Doctrine on the Church Mysterium Ecclesiae (24 June 1973), 5: AAS 65 (1973), 403.
