Christians

[Zenith]

Our arguments are generally intelligent, thought provoking, and not based on a book.

To answer your question, I find it unbelievable that people of the same religion cannot agree on a single book, how hard can it be. It matters because where I live (Uk) Christians are still are fighting other christians.(northern Ireland)

This is an old post of this thread, but I thought about answering it:
First off, consider that there are a lot of denominations of christianity, where people of each denomination blindly believe its doctrine and its pastors and are eager to show how others are wrong and themselves are right, i.e. they (95%+) are not interested in seeing how things actually are, they are only loyal to their own religious parties.

So, to answer the question "how hard can it be?": if - as it actually happens - people are not open-minded (i.e. they don't want to listen what others have to say), then it is... impossible.

There is obviously also the issue with indoctrination (you put an idea in 1000 people's heads and they'd die for that idea) and with the study (i.e. most christians never read their bibles - I mean, the whole bible). So how can they agree on a book they never read??
