Hmm....interesting perspective. You do have a good point there.
BTW, I am a commoner and a peon - no formal education and I can sit through a Mass said in Latin (either the 'old' Mass or the 'new Mass') and I know what is being prayed. Most parishes that use Latin also provide little missals with the Latin on one side and the English on the other side for those who would like to use it. The homily (reflection on the Gospel) is always in the vernacular. Sometimes, when I have been in a foreign speaking country, I wished the homily was in Latin so I would at least get the gist of what the priest was saying. For example, last year I was in Quebec and the Mass and the homily was in French and I was completely lost.
