Zondervan has killed all its links for the Christian Writer's Manual of Style, as has (virtually?) everyone else. However, you can still get it. If you are interested, you should follow these directions AND save it ASAP.
You can get it using the Internet archive, Wayback Machine. Go to

Jan is right that the best course of action is this: “if you're writing for a particular publication, try to find out their preference.”
I also agree that the Zondervan/Christian Writer's Manual of Style is influential. However, it has its idiosyncrasies, as does every style manual. (And I say that as someone who has had his material published by Zondervan. (Not to overstate, I authored the first draft of about a page or so of someone else’s book, which was published by Zondervan in 1992, for which I received attribution.) I will not hijack the thread by noting all my disagreements with this Manual—it suffices to say that it is BOTH influential (and thus worth saving to your computer) AND not perfect.
However, interestingly, the Christian Writer's Manual of Style exhibits one of those idiosyncrasies with regard to the very question addressed by this thread AND (in an extremely low key manner) introduces a problem with capitalizing deity pronouns: It says EVEN IF one opts to capitalize deity pronouns, one should not capitalize “who,” “whom,” and “whose.” Really??? Apparently, these are the ONLY pronouns that should not be capitalized. While some of these words can—in different contexts—function as different types of pronouns, I assume the Manual advocates non-capitalization when they serve as relative pronouns. Yet the Manual gives NO reasons for not capitalizing this subset of relative pronouns while allowing (presumably) the capitalization of other relative pronouns and (by clear implication) all demonstrative, personal, (objective, subjective, possessive), indefinite, interrogative, reciprocal, and reflexive pronouns (as well as other categories if we split the hairs more finely).
As I mentioned, the Manual’s advice highlights a problem. Many writers—including Christian writers who might have an instinctive or principled reason for capitalizing deity pronouns—don’t understand English grammar at a technical level and therefore don’t even recognize all pronouns that ought to be capitalized (again, assuming that one has chosen to capitalize deity pronouns).
By the way, I don’t find this link’s (
http://www.markandlauraward.com/blog/20 ... -to-deity/) advocacy against full-on deity pronoun capitalization persuasive. (It either posits silly non-existent ambiguities or addresses issues that are actually translation issues). BUT, the link is still useful for other reasons. (Thanks, Jan.)
