The Bible has not been "interpreted" many times or "rewritten". What it has been is translated to many different languages. That does not mean the message has changed. For example, I am 100% Romanian and speak it fluently. In my language, good night is "nuopte buna". Literally translated it is "night good". Did that change the meaning? I think not. The Bible as a "book" holds so much of a "purpose" these days not because of the ink on the pages; but rather the Divine inspiration. As Jesus said, " Heaven and earth shall pass, but my words shall not pass". It is the Divine message and influence of God that brought Christianity Fromm 600 million in 1910 to 2.3 billion in 2012.
