But it hasn't remained unchanged at all. Just look at how many different versions of the Bible there are, and how many different sects of Christianity.

It's really more like "different translations" than the bible actually changing. If you can read multiple languages, you can read the untranslated texts easily enough.

As for the different sects of Christianity, that's more a difference in how cultures and individuals react to the bible than a change in the bible itself.
