Hildebrand's Overthrow of the West

The video linked below addresses more documentary evidence of how the monk Hildebrand (future Gregory VII) overthrew the See of Rome, and eventually the entire western Church, by illegal means:  Peter Crassus’ Defense of Henry, and Bishop Guido of Ferrara’s “On Hildebrand's Schism”.  It also shows that the western mind-set was very much Orthodox at the time of the East-West Schism, such as symphonia between the Emperors and Patriarchs, the ability for Popes to be deposed, and the general rejection of Gregory VII.
