For this series we're going to focus on how to think about the fall of Adam and Eve, what some call "original sin," and how that relates to evolution.
Now, I've explored some ideas on this subject before, linking the evolution of consciousness (the onset of our "knowledge of good and evil") to the start of our moral biography with God. I've also tied this view to the existential crisis death creates for finite, mortal creatures (death as enemy and curse).
But in this series we're going to explore a different perspective, a view that comes from the Catholic tradition.
To start, most of us think about the story of creation and humanity as story going from past to present. We try to puzzle out a chain of cause and effect. So, we set down two timelines, the story in Genesis 1-3 against the timeline given to us by the cosmological and biological sciences. The Big Bang. Stars igniting. Planets coalescing. The emergence of life. The Cambrian explosion. The dinosaurs. The evolution of Homo sapiens. How does that timeline align with Genesis?
We tend to tell this story prospectively, from origins to the present day. But there's a different way to tell the story. We can come to see the story of the past in a different light. Sin, death and the fall only come into view retrospectively, in the wake of our experience of Jesus Christ. Phrased differently, sin, death and the fall are less events in a timeline than apocalyptic revelations as to the meaning of prior history.
From the Catechism of the Catholic Church:
The point here is that we don't really need to get the timelines of Genesis and science sorted out and synchronized. We're free to let the "facts" of prior history be told and revealed by science. But the meaning of that history only comes into view with the life, death, burial, resurrection and ascension of Jesus Christ. When we come to know the source of grace, Jesus Christ, we at the same time come to understand Adam as the source of sin.Only the light of divine Revelation clarifies the reality of sin and particularly of the sin committed at mankind's origins. Without the knowledge Revelation gives of God we cannot recognize sin clearly and are tempted to explain it as merely a developmental flaw, a psychological weakness, a mistake, or the necessary consequence of an inadequate social structure, etc. Only in the knowledge of God's plan for man can we grasp that sin is an abuse of the freedom that God gives to created persons so that they are capable of loving him and loving one another.
With the progress of Revelation, the reality of sin is also illuminated. Although to some extent the People of God in the Old Testament had tried to understand the pathos of the human condition in the light of the history of the fall narrated in Genesis, they could not grasp this story's ultimate meaning, which is revealed only in the light of the death and Resurrection of Jesus Christ. We must know Christ as the source of grace in order to know Adam as the source of sin.
