My friend was having trouble reconciling the fact that I am both a scientist whom she respects and someone who calls himself a Christian. How do I tell my friend that being a Christian has not always been foundationally defined on belief, but a transformative way of newly living, a faith?
As much as we like to speak of a mystical union with Christ and as much as many of us continue, week after week, to affirm it, this mystery of our partaking of Christ's person is not a mystery that we consistently embody or appreciate.
The born again experience doesn't require a specific set of beliefs, but rather a specific social/emotional process; dogmas or explanations are secondary. It's not an experience unique to Christianity.
