Fides et Ratio §8

⁸ Restating almost to the letter the teaching of the First Vatican Council's Constitution Dei Filius , and taking into account the principles set out by the Council of Trent, the Second Vatican Council's Constitution Dei Verbum pursued the age-old journey of understanding faith , reflecting on Revelation in the light of the teaching of Scripture and of the entire Patristic tradition. At the First Vatican Council, the Fathers had stressed the supernatural character of God's Revelation. On the basis of mistaken and very widespread assertions, the rationalist critique of the time attacked faith and denied the possibility of any knowledge which was not the fruit of reason's natural capacities. This obliged the Council to reaffirm emphatically that there exists a knowledge which is peculiar to faith, surpassing the knowledge proper to human reason, which nevertheless by its nature can discover the Creator. This knowledge expresses a truth based upon the very fact of God who reveals himself, a truth which is most certain, since God neither deceives nor wishes to deceive.
