Your friend seems not to be well acquainted with Biblical scholarship. According to the framework view, Genesis 1:1 depicts the earth as already existing in a chaotic state when God begins 6 days of setting things in order. According to the functional view championed by John Walton among others, Genesis 1:1 depicts a world without function. God brings function into the world with 6 days of work and makes it a place for his “rest,” which is not the opposite of work.
In my opinion, arguing that the concordist interpretation is the only game in town is an argument based on ignorance. If you want to argue that it is a better interpretation than ones based on cultural context and literary forms, feel free to make that argument and I will listen respectfully. But to claim it wins by default is just … an argument from lack of scholarly study.
I do want to thank you for working so hard on summarizing Behe’s argument. Very effective writing! Behe’s argument that the frequency of protein fold mutations is identical to the frequency of the regulatory gene mutations involved in CR seems suspicious to me. Since I am not a biologist, though, I do not trust my feelings on the matter. I will have to read Behe’s book alongside critiques by other qualified biologists to see what emerges. I have no time to do so for several weeks, if not months, so I will have to bow out of the conversation for a while.
May this Advent season prepare you and yours to proclaim the coming of our Messiah!
