Though I’ve never understood how God could expect his creatures to pick the one true religion by faith — it strikes me as a sloppy way to run a universe.

In the "original uncut" edition (1960, published 1991), this is given as: "I've never been able to understand 'faith' myself, nor to see how a just God could expect his creatures to pick the one true religion out of an infinitude of false ones -- by faith alone. It strikes me as a sloppy way to run an organization, whether a universe or a smaller one."
I presume the more recent “original cut” edition is based on, if not identical to, the original 1960 manuscript, available on the Internet Archive site here: http://bit.ly/2lGCzyX. The Preface makes an interesting read. BTW, there’s a minor typo (I think) in your “original cut” version: “infinitude of false one” (singular) should be “infinitude of false ones” (plural).
