 :thanks for the latest edits Roger, probably a very minor thing but I really don't like th phrase ""rolled back"", so I've changed that to ""drew back"", though i must admit I'm not 100% convinced by that either.  I think the article could also do with a first header somewhat higher up, we seem to have an incredibly long lead at the moment.  Perhaps something like ""Earlier attempts at liturgical change"" following the first paragraph would make the article a little more readable?   "
