The role of religion is to integrate the Cosmology and the Morality, to render the cosmological narrative so rich and compelling that it elicits our allegiance and our commitment to its emergent moral understandings. As each culture evolves, a unique Cosmos and Ethos appear in its co-evolving religion. For billions of us, back to the first humans, the stories, ceremonies, and art associated with our religions-of-origin are central to our matrix.
I stand in awe of these religions. I am deeply enmeshed in one of them myself. I have no need to take on the contradictions or immiscibilities between them, any more that I would quarrel with the fact that Scottish bagpipes coexist with Japanese tea ceremonies.
