After an initial poll with a number of choices, there is now a shortlist of three:
- Extraordinary form/use
- Traditional Latin Mass or TLM
- Tridentine Mass
Of those, I'd vote for TLM. But I'm sticking obstinately to "Classical Roman Rite". The word "classical" does not have to refer to the Greek and Roman classics: we speak of "classical music" after all. I'm going with definition 3 of the COD:
"3 a in or following the restrained style of classical antiquity. (cf. ROMANTIC).
b. in or relating to a long-established style."
