Bartholomew Kuma is always seen holding this book (a bible)
What is this book?
EDIT
What type of bible is this? Just a regular bible, a bible from the One Piece world, or what? Is he some kind of priest? His shirt has same pattern as the bible.

It's clear from the pic that it's The Bible. And I believe that there is only one Bible (content-wise). About different versions - they're all translated from the original Bible. You can get a clearer view about the different versions of Bible here.
Kuma is an enormous man, (22'6" feet tall). He is the tallest remaining Shichibukai (being one inch shorter than former member Gekko Moriah) and is usually seen carrying a Bible.

Here's a pic depicting the name of the book much more clearly.
Assuming the Bible to Kuma is a religous text or historical account, the one he carries cannot rationally be any complete version of the Christian Bible that exists in our world without adding extreme plot elements that do not exist in universe yet or having the Bible be fiction in-universe. These changes are not merely a sudo-Christian faith which we can infer already exists somewhere in universe and is not (alone) a major change.
Any version of the Bible makes reference to specific places and historical details (such as the Roman empire) that are undeniably real. These places do not exist in the One Piece Universe. I can only come up with the following ways to have his version be an exact duplicate of a real version: a sea identical to our world, accessible parrellel universes, the book from another planet, or OP world is a post apocalyptic version of our own.
Any of these would be large changes to the One Piece universe and, therefore, should be considered unlikely at this point in time. The assumption should, therefore, be that Bartholomew Kuma's Bible is a version that does not exist in our universe. The core concepts of the Bible do not need to be changed.
As the cover mentions, it is a Bible
The Bible (from Koine Greek τὰ βιβλία, tà biblía, "the books") is a canonical collection of texts considered sacred in Judaism and Christianity. There is no single "Bible" and many Bibles with varying contents exist.1 The term Bible is shared between Judaism and Christianity, although the contents of each of their collections of canonical texts is not the same. Different religious groups include different books within their Biblical canons, in different orders, and sometimes divide or combine books, or incorporate additional material into canonical books.
