The Book of Divine Worship, the edition of the BCP approved by Rome for Anglican-use Catholics, is far inferior to some of the Anglo-Catholic adaptations of the BCP, such as the St. Augustine's Prayer book or the Anglican Service Book.
It makes use 1 of the 1979 BCP, plus it apes the Novus Ordo's Eucharistic prayers. "for all" in the consecration instead of "for many." Not to mention the inclusive-language Psalter.
But if it's a choice between clunky English and good theology, I know which way I'm headed.
(and it looks like the infamous "for many" is about to change.)
