    • When Western Rome fell, there was a massive power vacuum, so the Pope in the Western Church acted like the Roman Emperor of the West because he was the only unifying force in the West until the reign of Charlemagne and start of the Holy Roman Empire

  • The linguistic divide between the Latin-speaking West and Greek-speaking East, and the political, philosophical, and ecclesiastical realities those languages shaped

    • The West eventually developed the belief that the Pope had supremacy over the other four patriarchs
