When it comes to the doctrine of the origin of sin, does orthodoxy teach that we inherited our sinful nature from Adam?
Howdy RVincent!
Perhaps the best analogy I've heard to describe the Orthodox teaching on original sin and the Fall of Man goes something like this:
Think Adam and Eve as residents in a huge house where everyday they get to sit by the fireplace and be warm. They know that as long as they stay in the house that all of their needs will be met; they also know that if they leave the house they cannot come back in. Yet, one day they decide to venture out of the house. Once outside they realize that it is cold and hostile and, as they were warned, they cannot get back into the house. When they start to have children, those children are born outside of the house because that is where the parents are; they do not share any personal guilt for leaving the house, but they share in the consequences.
One of the more commonly misunderstood aspects of this story is that banishment from Paradise was not a punishment that God inflicted on mankind. The Original Sin did not put mankind in a position where God's sense of righteousness needed to be satiated (as some theories of Atonement propose). In fact, God gives (first) Adam and (then) Eve the opportunity to take responsibility for their sin, but both pass the buck, breaking communion with God.
Human beings were created for Paradise, and it is believed that once our forebears had reached a level of maturity where they would be able to handle the Knowledge of Good & Evil, they would have been granted to eat from that tree. As it was, Adam and Eve sinned by disobeying God and then refusing to repent, so God sent them out of Paradise before they could eat of the second tree from which they had been forbidden: the Tree of Life. Had they consumed that fruit while in a state of broken communion, they would have been eternally sinful.
If you are a parent, perhaps you understand the analogy of telling a child not to touch a hot stove because it will burn them. When the child touches the stove, you don't go and then hold their hand against it, but the child understands then that being burned is the consequence of touching a hot stove. Likewise, God didn't say if you eat of the tree of the Knowledge of Good & Evil I'm going to kill you, He said we would be subject to Death. When Adam & Eve sinned, they invited Death into the world and were made subject to him. Christ's Incarnation made possible our created intent, our reunion with God, and when He died he entered Hades and destroyed Death, freeing us from that curse.
So, to wrap this up...when God sent Adam & Eve out of Paradise, he sent the rest of creation with us because it is our life support system. When Christ was Incarnated, He transformed reality and restores not only us, but all of creation to its created intent. When we participate in that transformed reality and Christ's greace through the sacraments (transformed creation: have both a spiritual and physical component) that is living the Kingdom of God.
