Hebrews 2

(Heb 2, 1-4) God added his testimony by signs, wonders

[1] Therefore, we must attend all the more to what we have heard, so that we may not be carried away. [2] For if the word announced through angels proved firm, and every transgression and disobedience received its just recompense, [3] how shall we escape if we ignore so great a salvation? Announced originally through the Lord, it was confirmed for us by those who had heard. [4] God added his testimony by signs, wonders, various acts of power, and distribution of the gifts of the holy Spirit according to his will.

(CCC 156) What moves us to believe is not the fact that revealed truths appear as true and intelligible in the light of our natural reason: we believe "because of the authority of God himself who reveals them, who can neither deceive nor be deceived" (Dei Filius 3: DS 3008). So "that the submission of our faith might nevertheless be in accordance with reason, God willed that external proofs of his Revelation should be joined to the internal helps of the Holy Spirit” (Dei Filius 3: DS 3009). Thus the miracles of Christ and the saints, prophecies, the Church's growth and holiness, and her fruitfulness and stability "are the most certain signs of divine Revelation, adapted to the intelligence of all"; they are "motives of credibility" (motiva credibilitatis), which show that the assent of faith is "by no means a blind impulse of the mind" (Dei Filius 3: DS 3008-3010; cf. Mk 16 20; Heb 2:4). (CCC 157) Faith is certain. It is more certain than all human knowledge because it is founded on the very word of God who cannot lie. To be sure, revealed truths can seem obscure to human reason and experience, but "the certainty that the divine light gives is greater than that which the light of natural reason gives" (St. Thomas Aquinas, STh II-II 171, 5, obj. 3). "Ten thousand difficulties do not make one doubt" (John Henry Cardinal Newman, Apologia pro vita sua (London: Longman, 1878) 239).
