This gets back to jarhyn's larger point about the reader, knowledge and purpose. Does a person's bible have a purpose? For some people it's the recipe for making a god and so it's inerrant. For another person it's an object of curiosity. It can be literally anything on wishes depending upon what purpose - or purposes - one assigns.
Yes, I think so. Although assigns implies that a purpose for reading is pre-assigned, which I guess it often isn't. I doubt it's necessarily post-assigned either. I would rather say merely that it can be read (or listened to) for a number of reasons (including curiosity but also because one is taught or instructed or encouraged to read or listen to it) and that one can get different things from it, if one is permitted free choice to do that, and even if one isn't.
Possibly after the first reading, certain meanings and purposes are sometimes assigned thereafter, yes, but probably not always, by all readers. Some (possibly many) may be at least somewhat continually looking for new understandings, or at least new nuances, and be open to them.
I sometimes think of it as a self-help book (with the NT in particular having Jesus as a sort of life coach). Though it's a tad more confused than most modern books of that type, probably because it was as I said written by several people not necessarily all working together, even if riffing off one another.
I think it's fair to say that it is a sort of fetish book in western or western-influenced culture. In other words, I think it has undue influence (here we are talking about it, yet again, on a secular/atheist forum, for example, and giving it at least the time of day). Atheists especially might easily consider it largely a load of very old, superstitious bollocks. Other non-believers may see that even if that were true in one way (which I think it is) it still contains interesting and useful human ideas (some less outdated than others and some not much outdated at all), which imo it definitely does. But as a guide to life? I'd say, take away the bits you like, but read lots of other stuff too.
