III. The Characteristics of Faith

From The Catechism of the Catholic Church

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”.²⁸ 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.”²⁹ 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”.³⁰
