I remember playing as a child with my comrades on the playground before we could be "caught" playing Mass and reprimanded by the teacher, we said that High Mass was at noon. Where did I learn that term High Mass from? I never attended a High Mass in my life, let alone understood what one was. That is my only memory of anything at all related to the old mass. And the only reason I recalled that childhood memory was because I recently learned that there is a High Mass and Low Mass.
So go ahead take the time to at least read through those documents above if you have been poking around already wondering and want something concrete and authoritative- they are short and easy to read. Oh and I read this inspiring quote as well. Pope Saint John XXIII said about the value of Latin, "The Catholic Church," he explained, "has a dignity far surpassing that of every merely human society, for it was founded by Christ the Lord. It is altogether fitting, therefore, that the language it uses should be noble, majestic, and non-vernacular" (Veterum Sapientia, On the Promotion of the Study of Latin).
