The "genealogy" thread made me think about the following:
One of the big problems in reading the Bible comes from its practice of simply juxtaposing different stories apparently relating to the same "events": the two creation accounts in the first pages of Genesis, the Flood narratives (although there is some redactional weaving there), Samuel-Kings // Chronicles, and of course the four Gospels.
Our theoretic (=> spatially-structured) mind tends to put the stories side by side (synopsis) to compare them: whether we use the comparison to criticise or to harmonise, we actually build a third (or fourth, or fifth) story of "what really happened" (even if it is close to nothing) and then look back to see how the alternate narratives developed from it.
I don't mean that this approach is wrong (we can't help it anyway), but I would suggest it does make us miss something, which we cannot get without some ability and willingness to forget (actually, pretend to) what we already know when we enter another story.
And that works not only from one book to another, but also within the same book. We cannot really get into Genesis 2:4bff without "forgetting" Genesis 1:1--2:4a, etc. Yes, they are different traditions, but they were juxtaposed without any sort of (chrono)logical connection, constraining the reader to forget the first one as s/he gets into the second one.
Another example (actually I started from this one) is the nativity stories. Luke begins with an enormous miracle making Jesus "Son of God" right from the start; but then he has us forget it to get into the childhood stories, where "his father and his mother" do not understand how come their child is different! And he has us forget it again to get into the revelation of Jesus as Son of God at baptism, at the transfiguration, and so on.
All of this makes sense in the ancient practice of community reading, when you came to the synagogue or church to hear one short story (parasha or pericope) and then think about it (or not) and let it fade before hearing another story the next saturday/sunday. There was no problem (or less) about different stories making a similar point (which point did not belong to history). The Bible texts were never designed to be read "from cover to cover". But they are.
