Actually, the Throne of the Caesars was claimed by the Byzantines and then by the Carolongians. The papacy had no authority beyond the pale of the city of Rome, in fact less than that as Northern Italy was overrun by Lombards, Spains by Arian Visigoths, Gaul by Franks, Britain by Frisians and Angles and Saxons, while Southern Italy was still held by the Byzantines.
I cannot take time now to answer your posts as I must go to work. Perhaps tonight..but any are certainly free to dispute what they will...and usually do in order to somehow make out the Inquisition was not that bad. It was and the Internet has volumes of information for any to seek the answers...People who denied the Holocausts also attempted to defend what happened...but it happened none the less and just as we know the evidence is plentiful.
