"confusing mumbo-jumbo"
Latin? Gee. I learned latin well before I went to high school thanks to the liturgy.
Why did you post this. Now my blood pressure is up again.
The problem we have in the U.S. in particular is we are monoglots about language. If it's not English, it's bad. Not of all us, but it is a dominant mentality. Aversion to Latin is and was strongly correlated with "Americanism" in the Catholic Church.
That being said, any one with even small intelligence can learn and should learn Latin (if Catholic). It's all the more easier to do as a child who is immersed in the Latin Mass.
If the Latin Mass is brought back full scale, it needs to foster actual vocal participation (as is the case with many Tridentine Parishes today).
