Quote from : The Illusion of "Truth": The Real Jesus Behind the Grand Myth Book

Understand that religion, at least western versions of it, rests on a type of thinking called Revelation. This mode holds that truths concerning the workings of reality are hidden, masked by, through or behind a deity such that only a few privileged souls are able to see through the veil and “reveal” those truths. . . But (around 1600) revelation as a means of understanding began to be challenged by two other methods of differentiating truth from fallacy: Reason and Empiricism.
