Mike Beidler posted this as his status update on Facebook and I asked for permission to quote him:
To say that if any part of the Bible is of the myth genre, so goes the rest, is to present a blatantly false dichotomy. Disregarding the fact that Genesis contains etiological literature (i.e., origins myth) is actually a “low view” of Scripture. It disrespects the text(s), outright censors the ancient voices that produced the text(s), disregards authorial intent, and is guilty of the worst forms of theological ventriloquism.
