In the 1970s, Karl Menniger published "Whatever Happened to Sin?" The book pointed out the ways in which culture had abandoned the notion of "sin" as an important category for thinking about what's wrong and why things go wrong, and replaced it with terms derived from the realm of psychotherapy.
I wonder if we're not in a similar cultural moment, one in which our conception of the "location" of "evil" is shifting. In classical Protestant terms, sin/evil is located in each and every one of our rebellious hearts; we need a Savior. The therapeutic revolution moves the locus of evil to maladjustment, bad parenting, low self-esteem, etc.; we need a therapist. Various other social movements will locate or "explain" evil in terms of large corporations, centralized authority structures, or authoritarian ideologies; we need a raised, revolutionary "new consciousness."
Information technologies offer a fresh "take" on the human dilemma. Sin/evil is caused by twinned lacks: of connectedness and of information. More than a few voices in the emerging church movement are calling into question our "standard" categories of sin/sinner, being "lost," and formulations of judgment and the possibility of eternal punishment. Several are advocating wholesale denial of the doctrine of "penal substitution," the idea that Christ bore the punishment for our sin; this, at least in a few quarters, is seen as "cosmic child abuse." A modified universalism--while no one is saved apart from Christ's sacrificial death, many (all?) are saved without knowing that their salvation has come through Christ--is gaining a fresh hearing. The idea of drawing lines that separate those "inside" from those "outside," the understanding that people who "don't know Jesus" are "lost," are being viewed as outmoded, unhelpful and possibly even evil.
So: do we have an opportunity to rethink and reformulate our understanding of sin, what it means to be a sinner, and what it means that Jesus is Savior? How might we respond to the cyber-optimistic contention that people are inherently good and desire to make a positive contribution to a community (the ideology behind craigslist or eBay or Wikipedia)? What are our emergent brethren onto that we (those of us who might not be sure that the emergent label looks good on us) ought to pay attention to in regards to sin and salvation?
