In the periodic table of the elements, the "periodic" part refers to the columns, here it seems to be the lines somehow.
All right, I'm in nerd mode now - it would be fun to have "weight" numbers in terms of number of verses...
And personally, I'd put all the apocalyptic prophecy books into some kind of "transuranian" category - the plutonium equivalent of scriptures. Hazardous material, handle with care.
The non-canonical Gospels would be some analogue to isotopes? Decayed, short half life?
Where to put the Book of Enoch, and other books that are not universally accepted as canon?
This certainly sparked my imagination. Thanks, @wil!
