How would the modern barbarian defeat the mainstream conservative? The scourging and decapitation of Edmund the Martyr and enslavement of Findan would be unnecessary. All it would take is to call them a mean name to get them to surrender their country.
It is no accident that the Schism of 1054 was followed almost immediately by the Norman Conquest of 1066, on the heels of the death of the last Orthodox Sovereign of Angle-land. The Papal pretensions for world dominion, HAD to render the English subservient to the Pope, before such could happen. After the Schism, all of the major errors of the Medieval period followed in quick succession, that was the basis for Luther’s rebellion, 500 years later.
It was no coincidence.
