For 1500 years, 300-1800, most people knew nothing about Christ while the popes/patriarchs slaughtered any opposition to their power, venality and corruption. I think I know more history than 99.9% of the people. A lot of the attraction of Islam that made conquest easy in parts of the Byzantine empire was the constant slaughter of Christians by “Christians” over trivial differences because those differences were a threat to wealth and power.

You have no idea what you're talking about. If you read the ancient sources, particularly those from about AD 300 to AD 700, you'll see that even the average person of that era had an opinion about very complex aspects of Christian theology. They discussed it as much as average Americans today talk about sports. Christian theology was an all-consuming passion for many Romans of that era and many people knew large chunks of Sacred Scripture by heart.
