I understand where your coming from but the bible has actually taken on its own connotation beyond that of its religious one. It really has two important meanings in the English language (even though its not originally an English word.) Let me see what happens when I dictionary.com it...
1. The sacred book of Christianity, a collection of ancient writings including the books of both the Old Testament and the New Testament.
The Hebrew Scriptures, the sacred book of Judaism.
A particular copy of a Bible: the old family Bible.
A book or collection of writings constituting the sacred text of a religion.
2. A book considered authoritative in its field: the bible of French cooking.
