Well, to start with, this isn’t how they defined it in the past: The BioLogos Statement on Adam and Eve. They’ve been progressively (and non-transparently) narrowing the definition of “traditional”, primarily so they can claim traditional readings have to be ruled out. That is aligned closely with their “revisionist” roots, and perhaps also a desire to obscure their history of positions.
So it has been “interesting” to see this picked up by RTB, ENV, and now AIG, most of them (except RTB) oblivious to the actual history of that quote.
