This is so very true. As much as my grandmother was a fervent, faithful supporter of our church, as was my dad, I think they would both be surprised by some of the things that have been “restored”.
As the parish cantor, I’ve also had many conversations with some of the elders of our church when I “sing something new” (which is always something “old” that they unfortunately are not used to hearing).
We still have younger parents who fondly remember their own First Holy Communion, and cringe when other parents bring their very young children (who have been fully initiated) with them to receive the Holy Eucharist. I will even admit to having similar concerns, despite my deeper appreciation for the tradition.
It’s going to take a steady persistent approach, and likely another generation before the faithful simply think of the “new” as the “old”.
