Interesting comments, and I mostly agree, but would say that my impression is that Biologos is a “big tent” organization, and I have seen many here express opinions and have read many articles that embrace a historical Adam as well as accept evolutionary beginnings, though not all of course. Walton is often quoted in his “Lost World” books, and he affirms a historical Adam, as well as many others.
There are often areas of common ground, and those are what are celebrated, though in an organization like this, there are also areas of disagreement.
