Yes she has explicitly rejected it, when she made the statement I quoted, about 1.5 years ago.
She recently acknowledged there is no evidence against de novo creation, but has not stated it is an acceptable position for evolutionary creation. The BioLogos Statement on Adam and Eve does not acknowledge de novo creation as a viable position.
There has been much discussion about changing this statement, but now, 2.5 years later, no change.
Well, I show in my book that this is not the case. I show several examples of traditional understandings of Genesis that have people outside the garden. The actual traditional position is mystery outside the garden.
Of course, you can disagree with me, but that is my point. It is established with evidence from historical theology. I’m not supposing a contemporary populist view, but the historical tradition.
