A "Christian Atheist" is a modern phenomenon, and our materialist culture is the heart of that perspective and one that's deeply misunderstood and flawed.

I'd argue St. Paul and other biblical era scholars would find a western atheist not only very Christian, but also having a very childish and ignorant understanding of reality.

When everything is a thing, we have no room to see the fractal nature of happenings through time and synchronicity up and down layers of abstraction. Reality is just as much an interactive story between narrative and conscious threads as it is space/time, matter/energy. We've lost the first personal perspective of that with our modern "atheism".
