I believe we had theocracy in Europe from something like the 6th to 17th centuries--does that sound about right to you?
There have been many social changes in 'Christendom' and the world at large in the last couple of centuries and dramatically more in the last century in our eyes.
During that time Christian mobs raged across Europe, slaughtering Jews, Muslims and other Christians, in the crusades; the church/state executed hundreds of thousands of "witches," and hundreds of thousands of Jews and others accused of heresy,
Yes, there has been much suffering, but can we paint today's Christian world as the one of dark eras?
all in the name of God, and all inspired by their belief in the Bible.
I think its more complicated than that. can we single out Christianity as the sole motivator for such atrocities? the religious passions behind much of the atrocities could have been one aspect of a more complex social reality. modern history has more than enough examples of genocide and strife in societies in which Christianity is not a factor.
I'm not downplaying the dark history of Christianity as it came to be a state religion, its simply that I believe that history has many layers.
can we point the finger at one point in history and say, 'if this religion would not be what society adhered to, history would have resulted in an outburst of enlightenment leaving all its negative baggage behind'?
Arthur C. Clarke thought so, and it might be a source for interesting alt history ideas.
