Just read chapter 10: The Worlds of Christendom. Reading the different types of Christianity, their traditions, and their beliefs of Jesus. How they built their churches, where they built them, and why they named them. Also learned about the Byzantine state, and Justinian's conquests of the old Western Roman Empire from the the Ostrogoths, Visigoths, and the Vandals, and their traditions of christianity. This was a very interesting read.
