In the early years of Christianity, if those who did not believe in Christ's divinity had prevailed over those that did, and they had therefore dominated and controlled Christianity before [let's say] the C5th and then through history and carried it forward to the present day, what would the C21st world be like in religious terms and what tangible differences would there be?
"Ebionites is a patristic term referring to a Jewish Christian movement that existed during the early centuries of the Christian Era. They regarded Jesus of Nazareth as the Messiah while rejecting his divinity and insisted on the necessity of following Jewish law and rites. The Ebionites used only one of the Jewish Gospels, revered James the Just and rejected Paul the Apostle as an apostate from the Law." wiki.
