Someone found this blog searching for the following question:
I'd be surprised if the searcher is ever going to see this post, but what would be the best way to answer that question? I was always taught to capitalize it, but I was also taught to capitalize pronouns for divine persons, and I've since concluded that that's not just unnecessary but a bad idea entirely. So should we capitalize the initial letter of 'Bible' or not?
I don't think the arguments against capitalizing divine pronouns apply here, since those arguments rely on the ambiguity of pronouns in terms of who they refer to. The issue is whether it's a proper name of the sort that we should capitalize. We capitalize proper names, which is why I mark it wrong when my students use the word 'god' with lowercase when they are referring to a divine being as if with a name. Some people think they shouldn't capitalize the word if they don't or aren't sure they believe in God or one god, but we capitalize the name 'Gandalf', and no one believes he exists.
But is it different with the expression 'the Bible'? After all, we're not capitalizing the first letter of 'the', and the presence of that definite article to begin with is unusual in a name. But then other names do begin with articles, e.g. the Superbowl, the Beatles, the Boston Celtics, the Kama Sutra. So there's no assumption that you really believe the Bible is holy. It's just treating the name as a proper name of the same kind as the rest of this list. My conclusion then (in the absence of any argument to the contrary or any considerations undermining the one consideration that I've given) is that we ought to capitalize the initial B in 'Bible' when using 'the Bible' as a proper name. This reasoning would not support capitalizing the adjectival form 'biblical'.
I guess this means I need to be making a note of this also in my students' papers. I'd been thinking this was the sort of thing people could disagree about in a way that isn't true of 'God'. But it appears that's not so. You get it wrong when you talk about the bible as opposed to the Bible (at least when you're talking about the Bible and not some TV show's backstory guide for the writers of the show, which is indeed a bible).
