I have to agree with biblical scholar Peter Enns, for instance, that Young Earth Creationism, especially when it argues that a Christian cannot accept evolution, is both “wrong and harmful.” The truth is: our minds and our hearts and souls all together can rejoice in the truth and redemption that are delivered by Jesus Christ. But this kind of attitude creates a false Either/Or for many young Christians: either they must accept what seems compelling to their minds, or they must accept what their parents are passing down to them. Many youngsters raised in the church, given this false and completely unnecessary Either/Or, will choose to leave their faith. Anything less, they’ll feel, would be intellectually dishonest.
So the entire post is worth the read. And what’s more, there is actual data to suggest that people are leaving Christianity because of the either/or false dichotomy presented to them.
