I find it difficult to discuss this topic without first addressing the scope of your question.
I would think that in any discussion of christianity, reference to the bible would be not only acceptable, but necessary. In a discussion of the languages that the bible was originally written in, the writings are some evidence of the usage at the time it was written. In a discussion of 17th century english, the KJ translation is some evidence of usage from that time.
In a science discussion, the bible is worthless.
Thus, the answer to the question "Is the Bible acceptable in discussion?" depends entirely on the topic of the discussion.
