Scott reasonably asks why this matters. Remember that I'm basically defending myself against a claim that theology without Gen 3 is incoherent. I'm making no attacks on anyone else's theology.
But perhaps I should. In terms of theology, a traditional treatment of Gen 3 may be OK, but I think in a broader sense it may be dangerous. In order to maintain it, it has to reject mainstream science, history, and scholarship. Read postings by people who deny evolution and critical scholarship. They end up creating a kind of conspiracy theory, where scientists and mainstream scholars are predjudiced against faith. If this were limited to Genesis, it might not be a big problem. But in the last couple of decades this kind of conspiracy theory has started spreading. It now includes a rejection of global warming, current social science understanding of sexuality, and the value of vaccines, and even the usefulness of masks in controlling Covid. We've starting seeing a resurgence of the flat earth. Not every conservative rejects every one of these things, but I think once conspiracy theory starts in dealing with Genesis, it's hard to avoid having it spread.
