Because most of the bible was written in ancient hebrew (similar to hieroglyphics) no one can truly translate the text correctly. Ancient Hebrew is a dead language so no one really follows the bible. Sorry to disappoint.
The problem is JESUS brought us this beautiful thing (CHRISTianity) and them for more than 2000 years humans have proceeded turn it onto something based on what humans want it to be. This is why I am a devoted CHRISTian who does not attend church.
Presuming you are asking about the overall message of the 66 books of the Protestant Canon, theologically, Jehovah's Witnesses seem to come pretty close, but like all heterodox sects they have some far fetched ideas. Practically, by far Mormons, though the Mennonite Church comes close.
Do any of you understand that there is more than one bible? Almost every single religion has a version of the bible. There is a Catholic, Christian, Mormon, Jewish, Islam, etc. And each religion has its own branches, and a bible to go along with them.
I can't imagine anything spiritual being connected to the bible. To follow everything in the bible is a sure way to getting arrested quickly. it's impossible to follow it word by word and live by it, you have to use your own mind, you were given that gift of choice...so follow your local laws before acting upon things written so long ago by multiple people. This is a really vague answer but there are so many bibles to people.
