Chapter 3
On faith
1. Since human beings are totally dependent on God as their creator and lord, and created reason is completely subject to uncreated truth, we are obliged to yield to God the revealer full submission of intellect and will by faith.
2. This faith, which is the beginning of human salvation, the Catholic Church professes to be a supernatural virtue, by means of which, with the grace of God inspiring and assisting us, we believe to be true what He has revealed, not because we perceive its intrinsic truth by the natural light of reason, but because of the authority of God himself, who makes the revelation and can neither deceive nor be deceived.
3. Faith, declares the Apostle, is the assurance of things hoped for, the conviction of things not seen.
4. Nevertheless, in order that the submission of our faith should be in accordance with reason, it was God's will that there should be linked to the internal assistance of the Holy Spirit external indications of his revelation, that is to say divine acts, and first and foremost miracles and prophecies, which clearly demonstrating as they do the omnipotence and infinite knowledge of God, are the most certain signs of revelation and are suited to the understanding of all.
