The Christian understanding of creation, original sin and our first parents is very controversial. Peter Enns has been at the center of the controversy for the past couple of years. Brian LePort has a short review of Enn’s recent book The Evolution of Adam. But he also links to a long series of posts that LePort has written about the historicity of Adam. If you are interested in this subject this is a good place to start.
This book is written by a biblical scholar who is convinced that the theory of evolution is the best explanation for human origins. Peter Enns is a Christian. He affirms the Bible to be authoritative to his life. For many these three sentences are contradictory: How can one affirm evolution, find the Bible to be authoritative to their life, and claim to be a Christian?
