This is an interesting contribution to discussion surrounding the fall and its effects. And I am sympathetic to some of what is being said. But despite that there are some things that bother me.
First there is heavy reliance on what the account doesn’t say, and at the same time perhaps a too detailed analysis of word choices in what it does say. For example, Eve says that God commanded them not to touch the fruit, whereas when God is quoted directly by the author the part about not touching isn’t there. Did Eve embellish or not? No way of knowing, the fact that the earlier account doesn’t mention it doesn’t mean that it wasn’t said. That Eve is embellishing is a very common interpretation, but I think it has to be pure speculation. God probably said a lot more to Adam than the few words captured here. With a word picture we have to be careful not to fall into the trap of over literalizing which YEC is so prone to. Even if the account were strictly literal we couldn’t assume Eve isn’t telling the truth.
But the bigger issue is that the interpretation fails to deal with the interpretation presented in the New Testament. Isolating a study of the fall to just the symbolic account in Genesis doesn’t yield much fruit that we can hang our hat on. Genesis isn’t a full theological explanation of the fall any more than it is a strictly literal historical account. We have to turn to the full range of New Testament interpretation for that. Any defense of a particular interpretation of the fall must take the whole of what the Bible says into account. All views of creation and the fall seem to center too much on Genesis 1-3 and mining the details for what may or may not be there.
I am not directly arguing against the theory presented. Just that it cannot be convincing without a more Biblically comprehensive analysis.
