Thanks for starting the new thread! 
Heresiarch, there is absolutely no need to be that agnostic about the contexts of the Bible. We live in an age in which we have more information on the Bible's contexts that any other people have had at any other time in history.
We have the Dea Sea Scrolls, the Nag Hammadi library, the Mishnah, Talmuds, the Jewish historians, we have early Christian documents like the Didache and all the other letters like those of Clement of Rome, we have martyr texts, we have a load of patristic texts which help us to know what the 'Bible' actually consisted of and how it was understood in the early years / centuries of Christianity, we have all sorts of documents from the ancient near east (like Ugaritic, Canaanite, Babylonian and Egyptian texts of all sorts), and a huge weight of Greco-Roman literature....just go and wander round the British Museum for a while if you want to start to apreciate the absolute wealth we now have of texts and artefacts that help us to understand the Bible.
You could choose to ignore all that say 'Well, this is what it means to me...', but that's somewhat anti-intellectual and, well, obtuse, really. If you'e not interested, fair enough - but the argument that the contexts of the Bible are unknowable and therefore subject to the whims of the each person is just wrong.
