“Professor Dave” misstates the genuine religious position. It is, for example, an “infallible teaching” of the Catholic Church that (and we quote), “absolutely speaking, human reason by its own natural force and light can arrive at a true and certain knowledge of the one personal God, Who by His providence watches over and governs the world, and also of the natural law, which the Creator has written in our hearts” (Humani Generis, § 2).
