The conclusion reads:
The gnostic Mithraists and Jewish Ebionites formed the very first Christians of the first century, with practices and beliefs based respectively on Gnostic and Judaistic rituals, symbols and practices. Pauline Christians dispensed with the difficult Jewish laws and became popular amongst gentiles, soon out-numbering the Jewish Christians, causing them to be secluded and eventually suppressed. Increasing literalism amongst roman converts then led the Pauline Christians to become obsessed with enforcing their literal interpretation of Christianities original stories, causing another huge rift with older gnostic-style Christians. With Roman power behind their printing press and the favour of Emperors, the Pauline-Nicene Christians wiped out the gnostics, annihilated the Arians after long bloody campaigns, and murdered and burnt the Marcionites and many other small sects, to leave themselves as the sole Christians within the Roman Empire, free to edit their own books to 'prove' how all their predecessors had been wrong. The three Cappadocian scholars promoted the Holy Spirit to the godhead to create a Trinity, which was codified strictly in to the Nicene Creed of 381, which went to careful lengths to disclaim against 'heresy'. Emperor Theodosius published a series of forceful edicts intolerant of all non-Nicene sects. This state of affairs persisted in the West for over a thousand years from the 5th century.
Despite the number of denominations that now exist, Christian diversity has never again regained the richness it had in the first few centuries. Christianity has remained, in the West, the Pauline, Cappadocian, Nicene victor that emerged from the ashes of Christian groups within the Roman Empire and Judea. It is a shame that it appears the most worldly, least spiritual, most power-hungry, least tolerant, most violent and least honest form of Christianity is the one that survived those brutal battles of the first few centuries.
