Do people prefer not to understand what is being said to them at Mass? Having had four years of Latin, understanding the Mass is no problem for me. I've also attended a Greek Catholic Divine Liturgy in Slavonic. With a missal and rudimentary knowledge of Russian, I was able to follow the service with nary a misstep. Being in conscious contemplation of the liturgy sure beats being the snoozing pew-warmer I was in my teenage years.
Number 1. People DO understand the latin in the mass. Just like you learn the melody to a song..you learn what the latin parts of the mass are. Number 2. I will be getting married at this church. It is gorgeous. Fr. Pasley does a great job...and they have the most beautiful crucifix I have ever seen over the altar.
