72 In language as clear as it is authoritative, the First Vatican Council condemned this error, affirming on the one hand that “as regards this faith..., the Catholic Church professes that it is a supernatural virtue by means of which, under divine inspiration and with the help of grace, we believe to be true the things revealed by God, not because of the intrinsic truth of the things perceived by the natural light of reason, but because of the authority of God himself, who reveals them and who can neither deceive nor be deceived”: Dogmatic Constitution Dei Filius, III: DS 3008, and Canon 3, 2: DS 3032. On the other hand, the Council declared that reason is never “able to penetrate [these mysteries] as it does the truths which are its proper object”: ibid., IV: DS 3016. It then drew a practical conclusion: “The Christian faithful not only have no right to defend as legitimate scientific conclusions opinions which are contrary to the doctrine of the faith, particularly if condemned by the Church, but they are strictly obliged to regard them as errors which have no more than a fraudulent semblance of truth”: ibid., IV: DS 3018.

106 In the same sense I commented in my first Encyclical Letter on the expression in the Gospel of Saint John, “You will know the truth, and the truth will set you free” (8:32): “These words contain both a fundamental requirement and a warning: the requirement of an honest relationship with regard to truth as a condition for authentic freedom, and the warning to avoid every kind of illusory freedom, every superficial unilateral freedom, every freedom that fails to enter into the whole truth about man and the world. Today also, even after two thousand years, we see Christ as the one who brings man freedom based on truth, frees man from what curtails, diminishes and as it were breaks off this freedom at its root, in man's soul, his heart and his conscience”: Encyclical Letter Redemptor Hominis (4 March 1979), 12: AAS 71 (1979), 280-281.

109 In the Encyclical Letter Dominum et Vivificantem, commenting on Jn 16:12-13, I wrote: “Jesus presents the Comforter, the Spirit of truth, as the one who 'will teach' and 'bring to remembrance', as the one who 'will bear witness' to him. Now he says: 'he will guide you into all the truth'. This 'guiding into all the truth', referring to what the Apostles 'cannot bear now', is necessarily connected with Christ's self-emptying through his Passion and Death on the Cross, which, when he spoke these words, was just about to happen. Later however it becomes clear that this 'guiding into all the truth' is connected not only with the scandalum Crucis, but also with everything that Christ 'did and taught' ( Acts 1:1). For the mysterium Christi taken as a whole demands faith, since it is faith that adequately introduces man into the reality of the revealed mystery. The 'guiding into all the truth' is therefore achieved in faith and through faith: and this is the work of the Spirit of truth and the result of his action in man. Here the Holy Spirit is to be man's supreme guide and the light of the human spirit”: No. 6: AAS 78 (1986), 815-816.

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 through 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): 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.
