[Avodah] Taking Midrashim Literally

[Richard Wolberg]

> ...certainly one who refuses ever to believe the literal meaning of a medrash is a kofer in the whole torah.
    Upon what source do you base this statement?

Certainly you are aware there are rationalist meforshim who interpret the incident of Bilaam's talking donkey 
in a NON-LITERAL manner. Rambam sees it occurring in a dream. The Ramchal suggests that the donkey
brayed plaintively and Bilaam intuited what it was trying to convey. And this is not a medrah; this is from the
Torah. Are they also kofrim? In addition, the Midrash lists Bilaam's donkey as one of the 10 miracles created 
by God in the last hours of Creation. So does that make Rambam a kofer because he didn't take it literally?
