, but I don't think that Latin responses, such as the altar servers make, are beyond the abilities of anyone with proper priorities who has a hand missal in front of them. (When I served the TLM a couple of decades ago, I always had to keep one of those little "cheat cards" in my hand, after all, the priest isn't required to memorize his part, why should the server be?) That is not terribly difficult Latin. People learn how to do various jobs, play sports, drive cars, cook from recipes, do math, learn basic historical and geographical facts, knowing the basics of the TLM shouldn't be any different. It's all about priorities.
I agree with most of what you say but it does pose a problem, at least for me. Being in the choir over 50 years ago, we sang the responses so we knew them well, but we didn't know what we were saying in English. One can learn almost anything by rote given enough time but are we truly praying? We pray in the language we understand and speak. Prayer involves a certain amount of emotion and when praying in latin or any language foreign it becomes devoid of both emotion and inflection.
When praying the rosary in latin which I've done, the vocal becomes like a background monotone mantra to meditating on the mysteries: and if your mind wanders...how pleasing can that possibly be to God? And how many people just pray in latin in public to show off? If you stopped them in mid prayer and asked them to continue in English they'd be lost. And then there's the whole thing about not knowing the language and mispronouncing the words and thereby changing their meaning
When praying we should speak to God in a language where we know what we're saying and saying what we mean.During the Mass the altar server is there to speak on our behalf. That's their purpose. Let's leave them to it. Then we'll have enough time during Mass to fulfill It's ends...To Adore, To give Thanks, To make Reparation and finally to Petition
