Jay:  The"religion content of Christianity" has historic and cultural dimensions:
Is the Roman Catholic Church the last surviving relic of the great Roman Empire?
Is the Roman Catholic Church the primary preserver and sustainer of medieval and renaissance  fantasies, traditions, and fables?
Is the Roman Catholic Church  the logical future home for a science-based theology of Christogenesis as the cosmos evolves toward its full realization at Omega, a point which coincides with the fully realized Christ, envisioned by Teilhard de Chardin?
