How many different liturgical Rites (e.g. Roman) does the Latin Catholic Church sui iuris have?
What Uses does each of these Rites have? (E.g. I believe the Roman Rite has at least three Uses: Ordinary Form, Extraordinary Form, and Anglican Use.)
Which of these Rites/Uses are extant, only used on certain occasions, or now not used at all?
Were all Latin Catholic Church sui iuris Rites/Uses revised following Vatican II or do some only exist in their pre-Vatican II form?
Do changes to all Rites/Uses have to be approved by the Holy See, or, for example, could the Archbishop of Milan approve changes to the Ambrosian Rite?
As I’m in UK I’m interested to know if Aberdeen, Bangor, Durham, Hereford, Lincoln, Sarum, York (and any others that may have existed) were Rites in the true sense of the word of if they were Uses of the Roman Rite?
What is the current status of Sarum Rite/Use? I know Most Rev’d Mario Conti (Archbishop of Glasgow) celebrated a Sarum Mass in 2005.
If you can cite references/sources in your answers I’d be most grateful.
P.S. Are there definitions for Rite and Use (or is it Usage?)?
