If the take is religion is itself the weapon and the depiction given is mere evidence of that, OK, that's at least avoids the ending being totally awful. HOWEVER

The book spends much of its time saying the transcendent cannot even be represented, to people, to us the read -- then just represents it, and in a tawdry christian way.

I think the violation of that norm, as well as the ending being played straight -- with literally a long paragraph explaining with ideaspace is... that's a fourth-wall break into christianity imv

Which makes the whole book read as, "the issue with humans is our physical bodies in a fallen world which are limited. just die, go to heaven, then you can know/represent/understand everything. Yay! Death!"

OK. Just kinda naff.

It reads as a religious person who accidentally wrote a good sci-fi book then hurridly, at the end, reminds us all that its really a parable with a Noble Message that in Death all things are trascended.
