Stewart Lee had a good bit about this:

Racism always tends towards the silly, of course, but British ethnic nationalism particularly so, given the history. What’s ’British’, anyway?
I don't find this to be true. Even at high mass ('bells & smells' type communion) you get more modern versions. To my recollection NIV would be most common. Obviously not a representative survey. Also, it might be at traditional/formal services you get [N]KJV as I've been to less of those.
Amongst very old people you see strong support for KJV because that's what they learnt 70 years ago. It sounds very archaic to modern ears. I'd say KJV hasn't been favoured this side of the millennium.
Just my impression.
NIV is the preferred translation for the low-church side, the evangelicals, so definitely won't be used by the bells-and-smells high church crowd. KJV is preferred by a niche who also prefers the Book of Common Prayer liturgy over Common Worship. Usually this is either an older population, a certain ethnic subgroup with calcified traditions, or old-school low church folks (so not modern evangelicals) who prefer the old ways and even the Thirty-Nine Articles.
My understanding is that Old English vocabulary mostly predates Viking invasion, but even then the colonizers would have a large shared vocabulary with (non-Celtic) British natives, who would be the descendants of Anglo-Saxon settlers a couple of centuries earlier.
Latin influences English as a learned tongue, used by clerics and academics. Other than that most of it comes via French, when the Normans brought it.
Recent research, namely an article by Lars Nooij & Peter Schrijver [0], suggests that a population speaking Latin/Romance may have remained present in Britain until the late first millennium. Granted, the effect of this local Latin would have been on Welsh more than English.
