The transmission of original sin

1. Original sin has two sides: (i) the condemnation of Adam's sin and (ii) moral corruption/spiritual inability. (i) seems unfair. I've discussed that on multiple occasions. In this post I'd like to focus in (ii).

2. One question is whether the Bible teaches original sin. Considered in isolation, Gen 3 doesn't seem to teach original sin. However, that's followed by a drastic escalation in evil, leading up to the flood. And it continues after the flood. OT history is a record of pervasive depravity, both in pagan cultures as well as Israel. The extent and intensity of human evil is hard to explain unless there's a predisposition to evil.

In the NT, two classic passages are Rom 5:12-21 & 1 Cor 15:21-22. The text in 1 Cor 15 is about death, while the text in Rom 5 is about condemnation as well as death. 

Over and above that are Pauline texts about the moral and spiritual blindness, hardness, and deadness of the lost. About their captivity to raw destructive passions. Again, it's hard to explain that if humans are born moral blank slates. 

Finally, a theme of John's Gospel and 1 John is how the mission of Christ exposes the preexisting animus towards God and good. That dovetails with the Pauline picture.

3. A difficult issue in Christian theology is the transmission of original sin. In terms of guilt and condemnation for Adam's sin, that gave rise to debates over immediate and immediate imputation in Reformed theology. I think proponents of immediate imputation have the better of the argument. Again, that raises questions of fairness, but I've addressed that elsewhere.

4. But what about the transmission of moral corruption? What's the metaphysics or mechanics of original sin in that respect? That's something else theologians struggle with. Different models are proposed. 

Let's take a comparison: from what I've read, feral children are psychological inhuman. For normal psychological maturation to occur, humans require socialization during their formative years. There's a narrow window of opportunity that closes. If humans don't receive the necessary socialization during that period, no amount of remedial socialization will fix the deficit. The tragedy of feral children is the fact that they already passed the threshold where it's possible for them to develop a normal psychological makeup. No matter how much affection and attention they receive, it's too late for them to become psychologically human. It would take a miracle (which God may provide in the afterlife.)

Nothing was done to them that directly caused that deficient. They weren't physically, verbally, and psychologically abused. Rather, their condition is the result of severe neglect.  Humans aren't like Jem'Hadar babies programed to automatically mature psychologically as soon as they pop out of the incubation chambers. Our psychological makeup isn't purely internal and self-contained, waiting to unfold like clockwork. To be psychologically complete and mature requires something from the outside.  

By analogy, the transmission of original sin needn't be caused by some positive factor or determinant, but by the absence of some external factor that's necessary to complete our moral formation. Something lost in the Fall.
