I think you're shoehorning the metaphysics (is that the right term here?) of afterlife and divinity into group 3. While "transcendence" is a good catch-all term for, let's say, claims about the non-empirical world (which I guess would be, by default, non-falsifiable), the ideas of life after death and who's calling all the shots are further apart than, say, moral precepts and faith-based precepts, imho, and they have separate groups. Afterlife deals with the very personal nature of the soul, whereas divinity is more about an idea of the world at large and how it runs. I'd be tempted to make 3 solely about soul-based metaphysics (is there a soul, what happens to it after death, and are we in fact more connected with the world than just regular physics allows), and nudge divinity somewhere between 3 and 4 (since it's empirical and, without getting too squabbly about it, non-falsifiable).

Also: where would you stick eschatology? Group 4?

Also also: I like your system, but I feel like there are probably non-Western religions out there - or hell, even some Western ones - that probably break the mold. Good tests waiting to be discovered. :)
