Sorry for the late reply. I like your choice of words, proto-philosophy. I think of religions of the past as proto-philosophy and proto-science (the world is flat and at the center of the universe, Heaven is structured so and so, ...). But you're right, my framework does not fully reflect the complexity of modern faith. Unlike trained priests, the overwhelming majority of believers don't learn philosophy to challenge their own beliefs.

imho too many people consume religion like painkillers for the big questions. Without a critical eye, faith becomes anti-philosophy.
