In a post titled "Request for Information on "Ad Experimentum" Rite at OLW" Christian notes:
Earlier today, the following message was posted to the Anglican Use Mailing List:
There was quite a surprise at OLW this morning: a new Order of Mass. I'll highlight changes that I recall. Hopefully others will chime in & comment...
This new Order of Mass, which Christian terms, rightly I think, ad experimentum, is being used in a handful of parishes in the US, Canada and England (and perhaps Australia, although I have seen no confirmation of that). There are restorations of traditional Anglican prayer formulae, but re-ordering of the service to bring it more in line with the Roman Rite.
To read a bit more about this, visit the Anglo-Catholic blog, and sign up for the Anglican Use newsgroup on Yahoo (there's a link in the sidebar to the left).
