Hebrews 11:3

Faith needs a generous and vigorous soul, and one rising above all things of sense, and passing beyond the weakness of human reasonings. For it is not possible to become a believer, otherwise than by raising one's self above the common customs of the world.

What then does Paul do? He encourages them by the fathers; and before that by the common notions of mankind. For tell me, he says, since Faith is calumniated as being a thing without demonstration and rather a matter of deceit, therefore he shows that the greatest things are attained through faith and not through reasonings. And how does he show this, tell me? It is manifest, he saith, that God made the things which are, out of things which are not, things which appear, out of things which appear not, things which subsist, out of things which subsist not. But whence is it shown that He did this even "by a Word"? For reason suggests nothing of this kind; but on the contrary, that the things which appear are formed out of things which appear.

Therefore the philosophers expressly say that "nothing comes out of things that are not" being "sensual" (Jude 19), and trusting nothing to Faith. And yet these same men, when they happen to say anything great and noble, are caught entrusting it to Faith. For instance, that "God is without beginning, and unborn"; for reason does not suggest this, but the contrary. And consider, I beseech you, their great folly. They say that God is without beginning; and yet this is far more wonderful than the creation out of things that are not. For to say, that He is without beginning, that He is unborn, neither begotten by Himself nor by another is more full of difficulties, than to say that God made the things which are, out of things which are not.

Whence does it appear, he would say, that God made these things? Reason does not suggest it; no one was present when it was done. Whence is it shown? It is plainly the result of faith. "Through faith we understand that the worlds were made." Why "through faith"? Because "the things that are seen were not made of things which do appear." For this is Faith. Having thus stated the general principle, he afterwards tests it by individuals. For a man of note is equivalent to the world.
