Christians can't agree on pretty much anything in the Bible, which is why there are thousands of different sects, and a Wikipedia entry for "schisms in Christianity" that is dozens of entries long.
I don't think that's a fair statement. For example, a large majority of denominations (I'd say >80%) agree on something like the Apostle's Creed [1]. But yes, for less core doctrines, there are sometimes dozens of flavors.
