Neo-orthodox theologian Reinhold Niebuhr once famously said that original sin is “the only empirically verifiable doctrine of the Christian faith.” But what was once “empirically verifiable” is now questioned, and even science is being enlisted as its primary foe.
As the story goes, modern science indicates that it is impossible for the breadth of humanity today to have been derived from a single human pair. If there was no single human pair, there was no Adam and Eve, as the fountainhead of all of humanity. If there was no Adam and Eve, there was no cosmic Fall. Without a cosmic Fall, there was no original sin.1
The conclusion? If the core element of Christian teaching is that Jesus saves us from our sin, then without original sin, the entire Christian story regarding salvation falls flat. Therefore, science has made original sin obsolete. … To continue holding to an obsolete doctrine means that the Bible can not be trusted… The Christian story of sin and salvation implodes…. POOF!!
This is a narrative that has become increasingly popular in the West, as seen from different angles. Many former Christians and other agnostics/atheists point to this as one of the primary reasons why Christian faith must be rejected. Liberal-minded Christians will tend to look the other way and ignore such difficulties. Others from a Christian background will use this objection as a means of rewriting the whole of Christian theology to build a completely different worldview.
