There’s a lot riding on that statement, and depending on what you mean by it, you might have already answered your question (albeit in a way that might be unsatisfying to you).
Do you mean to suggest that the PBC asserted that
all of Genesis 1-3 is strictly historical? That’s not what they said. Let’s look at the assertions in that document that are relevant to your claim:
Notice that this question doesn’t say that Genesis 1-3 is
entirely a literal, historical narrative. Rather, it only says that it is not possible to
completely exclude a literal historical meaning to these chapters. In other words, as long as there is (minimally)
one literal historical truth in Genesis 1-3, the answer in question #1 holds up.
But, what could “literal historical” mean here? Is the question more nuanced than a surface reading reveals? Let’s look at the next question:
This doesn’t help your case much. No, it cannot be taught that there are no ‘actual events’ that are described in Genesis 1-3; that is, that these are merely ‘fables’ that have been scrubbed of error or that there is no ‘foundation in objective reality’ to be found there. But… what is meant by ‘actual events’?
(There’s another interesting discussion to be had regarding the second part of the question – the part about ‘legends in part historical and in part fictitious’ – but I’ll defer for the moment.)
The ‘actual events’ are addressed in the next question:
Here’s where the rubber meets the road, IMHO. The ‘actual events’ that the PBC are defending are: * The creation of all things by God in the beginning of time
- the special creation of man
- the formation of the first woman from the first man
- the unity of the human race
- the original felicity of our first parents
- etc, etc
None of these is contradicted by, for instance, the theory that Feser puts forward (which has been noted in this thread). Of special interest is the notion of “the formation of the first woman from the first man”, for a few reasons (!), but nevertheless, none of these assertions precludes the kinds of suggestions that Feser makes, or requires a more literalistic interpretation of the creation accounts.
So – and perhaps I’m misconstruing your question – it seems that you’re taking these assertions of the PBC document and attempting to make it say something that it’s not saying at all…
Wait – you mean the historicity of a first man ‘from the red earth’ and a ‘mother of all the living’ (which is, in fact, what the Genesis accounts assert)? Yeah… that’s asserted doctrinally, and is all good. However, I think that you are asserting far more than that, right?
