Like most intellectual things, the bible is for you to interpret to yourself, and like most things, if you do not believe in God he will not exist to You. You won't understand complicated things like the bible to the fullest if you only know what others say it to be. Fact(or fiction) is naught if you cannot understand it to its fullest. As long as the essential message is true to the translations of the bible, it is not a true re-write.
Because there are many common ideas among interpretations of the bible, there are many subgroups and denominations within christianity(and other religions that reference the bible) which emphisize or ignore certain aspects of the bible, the Gospels, Acts, the Epistles, and Revelation, Such as the Pentacost.
Though this causes slight divisions within the christian church, as long as they don't Explicitly conflict christianity wont split into its own "religions." Examples of a explicit conflict is between Catholicism and Christianity, the Most notable is the "godification" of the virgin mary. Although christians believe mary to have been the holy mother of jesus christ, she is nothing more to christians. Catholics, however, seemingly worship the virgin mary as a near equality to Jesus Christ himself.
Then there are the Divisions of the bible concerning Islam and Judaism.
...But i don't think this thread is about the bible or diferences within reliegions concerning bible material, is it?
