Nothing could be further from the truth. Any translation of the traditional Christian canon will have the same 66 books (39 in the Old Testament and 27 in the New Testament), and any accurate translation will feature all of the major doctrines associated with Christianity.
Why, then, are there so many translations? The books of the Bible were originally written in ancient Hebrew, Aramaic, and Greek. Hence, any team of translators with a background in Hebrew, Aramaic, and Greek (and some serious time on their hands) can put out a new Bible version.
In the following video, Ed Gravely discusses whether having numerous Bible translations is a problem for Christians.
