Revelation 22:19  KJV

>And if any man shall take away from the words of the book of this prophecy, God shall take away his part out of the book of life, and out of the holy city, and from the things which are written in this book. 

When I first began to study the Bible in earnest I became intrigued by the Apocrypha, and when I spoke to my pastor about it he ignored my questions. Some other sources however indicated that those books had been rejected because they conflicted with that particular verse.

Through further study it became apparent that argument had no real backing. Since all of the books of the Bible were not written by the same person and over a very long time, and were not even compiled or even authorized until some years later.
