How about you celebrate your Eastern liturgy in LATIN. Do you like that idea?
Actually I have been interested in that possibility. It has already been done but I am unaware of any recordings of it.
I am sure the Divine Liturgy of Saint John Chrysostom would be stunningly beautiful in Latin. My guess is that it can be done at Grottaferratta, according to some of their older books.
As Ham1 stated accurately above, we do not have any real justification for applying Latin to the liturgy because there are no populations that speak it on the street or at table. There is also no nostalgia for it in the population, which is more attached to Greek and Slavonic.
The Greeks use an archaic form (of Greek) as a liturgical language, but it was once the common tongue. There are many who would like to see that updated to modern Greek and other modern vernacular languages in the diaspora.
The Slavs used Slavonic originally because everyone understood it in the ninth century, the only differences were dialects at the time. It is retained as a liturgical language by 2/3rds of the Slavic Orthodox around the world, something like Latin was for centuries. We have no problem with liturgical language but formally we agree the vernacular is perferred and accepted. We know applying the vernacular to worship was significant in the growth and spread of the church. It is historical fact.
The parish I belong to was established by Russians over 100 years ago. Today some of their descendants are still with us but we have moved on from Slavonic to English for most of the Liturgy since the 1970ās, I believe. My pastor does not actually speak Russian, but he can pray the Slavonic with no problem, if necessary, as can most of the clergy.
I like Latin. I have no preference of Greek or Slavonic over Latin, to me they are all the same. But I pray and worship in the language I know and use and prefer that. One can learn everything about what we believe just by following our liturgy and calendar, we pray our beliefs and for that reason catechesis is highly effective, even without a formal catechism available. This is why the vernacular has such an importance to us, especially in mission work.
