So what was the real sin here, and who was telling the story?
A parable such as this one carries a great message. As it moved through time, I have long felt that the message has been lost and reclaimed by the mantra of organized religion, and that is unfortunate.
If you think about it, the story reads as if it were written by the victims of a great atrocity, not the 3rd person omniscient God that kicked mankind out of the garden of Eden. It is a sad description of a change in mankind that changed his relationship with the world, not a simple story of a disobedient act being punished.
When I heard this story in church at a young age, I always though that original sin was man's flaws and something to do with how we are all bad people in need of the church to save us. All I needed to do was follow the program. Sing, sit, stand, love thy neighbor. I'm good as gold. I no longer believe this. I no longer really believe in the whole concept of salvation as a species, to be honest.
What was it that Adam got from the apple?
When man moved from being tribal nomadic beings to tribal settlers, there was a fundamental technology that took over the focus of these tribes. Farming.
Where men used to live as all other animals did, they began to take control of their environments. Man grew food where he needed it. Man penned up animals. Man built up social groups of like-minded people, and settled larger tracts of land and began to store food. Man's population did what any animal's population does in times of bounty, it grew quickly. With an increase of population came an increase in the need for farming, and system grew bigger. In terms of evolution, it didn't take long until the farmers began to infringe on the nomadic lifestyle. With farming comes the inevitable ownership of lands, which flies directly in the face of the way man had lived to that point.
Man had survived as a species for quite a long time without the concept of ownership. He lived in tribal families, yes, but he lived in a way that didn't upset the balance needed to find food. He couldn't afford to waste his food options. He moved with great herds. He predicted his supply and lived in harmony with the system that the earth provided him.
Farming provided something very different. It gave tribes bounty at times, and allowed tribes to work on the technologies themselves rather than follow the system as it moved around their habitat.
With farming also came another more sinister aspect: The elimination of competition. Anything that competes with a farmer's food supply is eliminated. This was as true five thousand years ago as it is today. A farmer is the most dangerous predator this world has ever seen. He has the knowledge to make food grow. He makes animals reproduce. He has the knowledge to know what must live and what must die in order to protect his food supply. He locks up his food. He eliminates anything in competition with him.
It as almost as if he has the knowledge of the Gods.
If you were to reread the parable of Adam and Eve with this type of lens, you might come to the conclusion that the story was not written by modern man. It was "written", or told, by the tribal nomads that were destroyed by the agricultural revolution. The knowledge of the Gods that Adam attained was the way he chose to live, and his removal from the garden of Eden was that he chose to live an intensely laborious lifestyle in which he lived not as all other animals did. He lived with the blood of the earth upon his hands, ruling over his domain, killing any species and any rival that competed with his food supply.
And, he still lives this way.
The difference in hearing the story from the perspective of the conquered nomads is that you can feel the loss they must have felt as the world changed around them. Our nearest comparison would be how native peoples here in North America were conquered, and how their way of life was taken from them by these same farming peoples. Buffalo all but extinct. Lands protected where they once hunted for food. Now penned into reservations, and the law of the land is the machine we call society. Population dictates more and more food production, and more food production dictates more population. A true native culture no longer exists, being replaced by the system with nothing but old stories and legends left to the culture.
Through all of this, we have forgotten how to hunt and fish. We work a more laborious lifestyle to feed ourselves than any generation of species on earth that has ever existed.
We are truly out of Eden, and no amount of ritual will "save" us. Because we don't truly want to be saved from the original sin. We want that salvation to come from uttering words, genuflecting, singing the hymns, showing up on Sunday, having sex properly, not getting tattoos, and dipping our babies' heads in water.
As a species, we don't really know what that original sin was, do we? And we will never know, so long as we continue to think that Eden is a place we go when we die.
