You see some truly ignorant people,and some bigots (and I'm not sure which Julian Assange is), think that medieval people were ignorant of the Latin Mass, their Faith in general and kept obsequious by the priestly overlords.
Now let's skip the fact that these people grew up as Catholics and went to Mass weekly, if not daily, and partook in many Feast Days (hence 'Merrie England').
There is little doubt they would have been imbued in their Faith from the cradle to the grave.
And the priestly overlords? Well in a society that was strictly hierarchical, just as the Lords kept the power of the King in check from below, as the Pope kept the power of the Kings in check from above, the priests could speak out for the sheep in their flock against possible abuses by Lords, as Bishops could speak out from above.
As Cobbett also made clear the "power" of the monasteries was also to provide succour to the impoverished, elderly, farm tenants and more.
After the "Reformation" the greedy Lords grabbed the land, enclosed it and created more poverty which ultimately led to the slums if the industrial revolution.
But above all else if we're to believe the lies of the stupid or the evil, i.e. that the "priestly class" lorded it over serfs whom they kept ignorant, can we ask why churches (which in medieval times were full of murals) had depictions of priests (and bishops) going to heaven - and hell!
If the priests wanted the faithful to all but worship them and regard them as all powerful, why would they remind the people that hell has its fair share of priests & bishops too?
That would make no sense, Mr Assange. But then neither would the Seal of Confession...
Oh. It's all starting to unravel isn't it?
