It probably would take a very honest organization (church or otherwise) to accurately self-present it's history, ugly warts and all.
By the time the apologetic spin-doctors get through, Moose, you wouldn`t recognise it. I bet the massacres, torture and burnings get the red pencil. Even more likely to get the chop are the unanswered prayers of the faithful. Let`s take the three MAIN rat plagues.
540 A.D.+ Byzantium--10,000 died each day at the height of the plague in the capital, 100 million throughout the empire.
1348 A.D.+ The Black Death--more than 25 million in Europe, half the population of Italy alone.
1900+ (officially ended in 1949, though there were 100,000 cases reported worldwide in the decade up to 1974)--figures still being assessed though Western countries tended to escape the worst of it due to better rat/hygiene control.(More Cunning than Man--Robert Hendrickson)
There were many minor outbreaks including the one that decimated the fourth Crusade.
Wonder how many Christians sent up a prayer for help before they died in agony? Will this be part of the history of Christianity? Or will it concentrate on 'tickling the ears'?
