I'm not "criticizing" it--I'm trying to understand why they are so fixated on it.
Background---I was brought up as a relatively "high-church" Episcopalian in south Louisiana in an area that was overwhelmingly Catholic. I often attended "traditional Latin Masses" with my Catholic friends when I would have "stay over" visits with them on weekends, and also when I was "courting" my very devout "cradle Catholic" spouse (which was about the time the Church was changing from the Latin mass to the Englich mass). From this background, I KNOW that the "reverence" level of a mass in English CAN match (and sometimes surpass, for native English speakers) that of any Latin mass. Add to that that I am a recent convert to Catholicisim (this Easter).
Now, I'll be the first to say that the current English-language Mass is NOT as reverent as those old Episcopal "Holy Eucharist" services, but that's because whoever did the translation from Latin to English had no "poetry in his soul". As a single example---read the Catholic version of the 23rd Psalm in English, and then read the same Psalm in the King James bible. Which of those two is the more reverent??
The "Latin Mass traditionalists" seem to think that simply changing the language of the Mass service will somehow correct all the negatives that have crept into the Catholic Church due to the excesses of liberals post-Vatican II. Here's a clue---it's NOT GONNA HAPPEN. The only thing that will cause that situation to change is to find out what the Church's teachings REALLY ARE, and stick to those (and yes, Virginia, as part of my deciding to join the Catholic Church, I "did" read all 800+ pages of the Catechism--on my own hook, as it was NOT taught in my RCIA class--which is indicative of the REAL reason for those "post Vatican II" problems).
But, my own particular take on the subject is that every Catholic church I know of (except for very small mission churches), has more than one Mass on weekends. So, do one of those masses in Latin, and the other in English, and let the chips fall where they may.
The truth be told, Latin being the language of the liturgy is only a side issue. The real issue is the reverence and fidelity to church teachings. Most people attend the Latin Mass mainly because they are sick of hetrodoxy from the pulpit, they are sick of no reverence what so over during the mass, they are sick of altar girls, they are sick of Lay Eucharistic Ministers, they are sick of the banal music, they are sick that they looked down upon for recieveing opur lord on their knees and so on. This is the reason why people go to the Latin Mass.
If the old mass was simpily translated into English, kept the same rubrics, and may some occasional Latin here and there, there would far fewer calls for the traditional Latin mass.
