"I believe it is physical, but extends to his nature as well. It has nothing to do with genes, which are a vehicle for communication between the Creator and his creation."
I find this statement confusing. You say that the physical image of God that was imparted to man has nothing to do with genes, but then state that genes are a vehicle for communication between God and man (at least). Could you please clarify?
"'Do you believe God is a supernatural, omniscient, omnipotent human being?' Of course *not*."
Then if God is not a flesh-and-blood human being who simply happens to supernatural, omniscient and omnipotent, how could we be made in the physical image of God?
