Just one more thought or question here, Andrew.
Can you tell me how you would see a non divine Jesus as being able to atone for the sins of all of mankind? To be, “the lamb of God that takes away the sin of the world,” as stated by John the Baptist in John 1:29.
The orthodox view is that it is the entrance of sin into the world and it’s ongoing existence here that is at the root of all of mankind’s problems. It would seem then that nothing would be of greater missional import then dealing with the sin issue. Anything less would be rather like putting a band aid on a gangrenous compound fractrue or a a cancer.
