Confusion of Realities

In Frye's chapter on the mountain, the first page states that the Christian "faith it calls for must be able to accept divergences from historical fact as one of its conditions" (Frye 144). When I read this, the first thoughts that came to mind were: true believers of this, unquestionably, have a confusion of realities. Lets take a present day student/believer...this student has been taught history, astronomy, biology, and literature by the time they have reached 16. All of these subjects teachings (assuming the student was at least some what conscious during class to take in this knowledge) would feel confused because of so many contradictions. That is, assuming this student is devout toward the calling of this faith. How can one truly accept the absence of historical events for the replacement of Biblical myths? Apparently one has to "accept the divergences". If I was a believer of this teaching, I would feel as if I was on a permanent acid trip...not knowing which reality; past or present was true. Delving into the Bible like this has allowed me to be satisfied and relieved with the fact that I was never raised on any Biblical or Christian precepts....See you in hell?
