The discussion of salvation leads naturally to the question of one of the most puzzling doctrines of Christianity: Original Sin.

Simply stated, the idea of Original Sin is that because Adam and Eve sinned by eating of the Tree of Knowledge (interesting that God commanded them to stay ignorant), they plunged the whole human race into a state of sinfulness. Recall that Matthew Henry wrote that “in a graceless soul, [. . . ] is empty of all good, for it is without God; [. . . and] this is our condition by nature, till Almighty grace works a change in us.” How could this have come about, though? By what mechanism could Original Sin enter the entire human race?

What exactly did Adam and Eve do? Two things: a physical act, and more seriously, a psychological act. They physical act, of course, was eating the fruit, whatever that might have been. The psychological act was going against the will of God – disobeying, in other words. Yet for something to affect the entire human race, it would have to be passed on genetically. How could either eating a piece of fruit or disobeying a command naturally affect a human’s genetic makeup? Of course, it can’t affect us at all naturally, but we’re dealing also with a supernatural element in the story of the Fall and Original Sin, so perhaps God somehow altered Adam and Eve’s genetic composition to pass on an Original Sin gene.

Yet this is starting to get ridiculous. “Sin” is a psychological and even spiritual condition. Despite various notions of “physical sin” and other twists, sin is not physical but spiritual and psychological. How then could it be passed on genetically? If it were, it would be discoverable. Imagine the headline:

Scientists Discover the Genetic-Theological Source of All Our Woes!

If it’s not passed on genetically, we are left with the unsettling conclusion that perhaps Original Sin doesn’t really affect us as much as it affects how God views us. Original Sin is a condition we’re placed in by God, thanks to Adam and Eve’s rebellion. Perhaps it could be explained by saying that God withdrew himself from Adam and Eve after the Fall, making it impossible for them to have access to the godliness they needed to live a life free from Original Sin, and that that gap is what Jesus’ sacrifice was intended to overcome.
