Postscript

Just as a postscript to Rick's post: Professor Enns must have changed his mind  on the historical Adam since leaving WTS as I have in my possession as Dean a letter from him, dated early 2008, which unequivocally expresses his belief in the historical Adam and its importance for Reformed theology. I guess he must have discovered some piece of evidence to change his mind since then, though I note that the videos don't actually cite such.
