Rome is the descendant of Egypt which is the descendant of Sumer/Babylon.

Christianity is the product of Saul/Paul and Rome, then first refined by Constantine.

Christ, Christianity, Church, and Christians are separate concepts that share information.

Egypt probably got the idea of writing from Sumer, but that doesn't mean that one culture is a descendant of the other - they grew up largely independently, at around the same time in history, around fertile river valleys. They do both give us a glimpse into a valuable point in the human spiritual awakening, a time 2000 years or more before the Nation of Israel was violently cleaved from its Canaanite counterpart.
