]No, you have not. Which questions about Christianity would not need us to first prove the existence of God? Do I have to prove the existence of God to explain why the Orthodox Church and Roman Catholic Church split? Presumably not. Do I have to prove the existence of God to explain why Arminians have a different understanding of predestination to Calvinists? If not, why do I have to prove the existence of God to answer the OP? Does not the OP assume, for the sake of the OP, that God exists?
All based on one kind of god belief or another, no one has been able to establish whether the god thing at the root of all you're referring to exsists or not; what is the point having any kind of dispute, fall out or argument unless there is some kind of confirmation about this god thing you keep referring to is an actual part of reality, in the unlikely event you were able nail this god idea as a going concern, well there might well be some point to further discussion, without the said confirmation, why bother?

You miss the point yet again. Alan refers to the Great Schism - the split between the Catholic and the Orthodox church - in his post. Now, I freely admit that the cause of this great division in Christendom was based on the most laughably pedantic mystic mumbo-jumbo, as well as the more immediate socio-religious consequences of whether the Roman Pontiff had ultimate authority.
It does not matter whether all this pother had any roots in ultimate religious truth or not. But the Great Schism remains an event of immense significance in European history and religion, whose repercussions had reverberations down the ages.
For historians, such phenomena remain a rich source for discussion, and most of them
do not spend their time arguing about whether the mystic imponderables involved are ultimately true or not. They observe that such things have occurred, and attempt to unravel their implications.
You seem to wish to completely dissociate yourself from European history, and believe that we could all make a new world if only everything could be reduced to "Belief in God is bollocks - next question".
Belief in God may indeed may be a load of bollocks, but in matters of history, religion and politics, nothing is ever quite that simplistic.
