Bonus blog post, following up from earlier. So, it seems the 1908 and 1946 editions are close -- there's a preface missing the later edition -- indeed, so close that the arranged version of the customary Luke 2 passage, read at Christmas shares a page number. But what's the reading based on?
It's Luke 2:8-20, essentially the King James version, with bits of the American Standard Version to (gently) modernize the reading. Reminds me of Linus's discourse in the Charlie Brown special. Good stuff.
