I'm sorry, but with my (admittedly broad and _shallow_) view of religious history, trying to see human relations through the filter of religion seems at least as fluid and relative as politics.

So much individual human mucking about with what could be basic universal principles. On one end, people who say that "this version of this written word is God's literal truth" when their version has a known history of edits, blatant rewrites, and translation errors. On the other end, recently started religions (Jainism is the first but not by far the only) that are at least as valid in their core principles but have their own dogma and assumptions.

Throw in Quakers etc who believe in a direct personal relationship with their God, and I can't see any consistency except "believe in us, and convince your friends! Their soul is in peril if they aren't with us!"
