Because I happen to be conversant with the older forms of English where "thou/thee" and "mine eyes" were normal, I think I am bothered more by (a) texts that randomly (as far as I can tell anyhow) switch back and forth, calling God "Thou" in one line or stanza and "You" in the next or vice versa, or (b) texts that read "My eyes have seen the glory" or "We give Thee but Thy own", than I am by competent and thorough modernizations. (Most hymnals that have tried to modernize "Dear Lord and Father of Mankind" have gone far beyond the pronouns, though. At least in the US "mankind" is nowadays frequently "humankind" ("Dear Lord embracing humankind" is the incipit of one published version I've seen), and some (especially UCC, the quondam Congregationalists) seem to feel there's something deleteriously patriarchal about calling God LORD.) When I switch from "thou/thee" to "ye/you" or back it's intentional and grammatically motivated, as in verse six of "In Bethlem Town", where the "thine" addresses Joseph alone, while the "your"'s encompass Mary and Jesus as well. But most modern English speakers, even literate and well educated ones, don't have a command of these niceties of Elizabethan usage.

6.God said to Joseph and his wife:
To Egypt go, to save your li-ee-ife.
Thine ancient namesake as a slave
To Egypt came your folk to save.

Too-loo-ree-lask, too-loo-ree-lun,

A sim'lar task awaits your son.

As you can tell, I'm back from the retreat of the last couple days. I wrote a little ditty on a wood louse, "The Potato Bug Hymn", to O Tannenbaum, while on retreat. See my forthcoming thread "Entomographical Hymnody: The Potato Bug Hymn".
