The Apocrypha is a topic that Roman Catholics and Christians debate over.
I have heard many different reasons why it is omitted from the Bible including:
1.)Not one of the apocryphal books is written in the Hebrew language (the Old Testament was written in Hebrew). All Apocryphal books are in Greek, except one which is extant only in Latin.
2.)It teaches immoral practices, such as lying, suicide, assasination and magical incantation
3.) Apocrypha includes doctrines in variance with the Bible
4.)Apocrypha contains fabulous statements which not only contradict the "canonical" scriptures but themselves
5.) I was told once that many wise men decided it to not be apart of the Bible
... but I am curious to hear why you say.
I don't know enough about the Apocrypha to know what language it was originally written in, so that's more of a question than a statement.
And because I am not well versed with the Apocrypha, I can not state with certainty that 2-4 are accurate.
The fifth reason I'm certainly not sold on. I find much wisdom comes from the moment that you've been foolish before, so how can I trust men to impart wise decisions onto a book that is God breathed?
