Well put! I am, too.
I appreciated Enns’ “Evolution of Adam” discussion of the Hebrew and Christian understandings of Adam and Eve, and their importance to the NT.
In my gut, I have a significant difficulty with any idea of God carrying responsibility from a progenitor (or any ancestor) on to current descendants; that is an ancient Near Eastern motif of corporate responsibility, and I don’t think translates to not just a Western, but a true, sense of responsibility. So, I don’t find GAE or even the Calvinist understanding of Adam congruent with a righteous God. Beverly Gaventa and Enns believe that Romans’ purpose is to rebuke Judaizers from giving restrictions to Gentiles, not to communicate a transference of responsibility. Also, Jesus referred to Jonah as a real person–and I am not sure that He opted to work outside the realm of what one would expect to know, or communicate, in his time. I’m not sure that his alluding to Jonah or Adam verifies their existence any more than their mention in the OT does.
Thanks for your reflections.
