Realistically, how much teaching do we need?
When the changes were implemented after Vat. II, we were told one Sunday that starting the next week we’d actually be expected to give responses at Mass (there was no dialogue Mass where I grew up) and it would be in French. No preparation of the assembly, the little folders were there the next week for everyone to use. The only ones who got preparation were the students if they wanted to attend the lunch time preparation. People who had never spoken in church before were now expected to speak out loudly – not a resounding success, still not where I grew up.
Today people are used to responding and, in my experience, most use missalettes to follow along. Simply telling them at the beginning of November that starting on the First Sunday in Advent there will be a different type of translation from that of 1970 so they will notice many changes in their Sunday Missal or missalette is going to be enough. I’m willing to bet that if we offer a workshop after Mass to explain the wherefores and the whys a handfull of people would be all that will stay for it and those will be 65+ years old.
