I was reading an argument the other day that said the invention of cheap and effective birth control was the death of Christian sexual ethics. The point was that in earlier eras when sex led more often to conception the prohibition of out-of-wedlock sex was more socially acceptable.
The interesting thing about this argument is the way it reduces questions of sin to material consequences. It is as if sin is not a spiritual matter at all. Perhaps for many people it is not, and that is why biblical teachings fail to hold when physical harm from sinful behavior is eliminated. We don’t actually believe sin can harm our spirit.
That apple is rather nice looking. It is good to eat. What can be the harm? Go ahead. Take a bite.
