Having gone through the transition from the TLM to the NO when I was a teenager in high school, I can assure you that there were large numbers of people who were not happy with it. We were told that that was the way things were going to be and we were reminded of our obligations to the magisterium of HMC. To say that the majority are fine with the NO may not be exactly correct. Many, many of us did not go gentle into that good night.
Unless I miss my guess, there are large numbers of us who are 50 and older who are not dead yet. The transition to the NO was quite abrupt. One Sunday we used the organ and sang traditional hymns like “To Jesus Christ Our Sovereign King” and the next it was out with the guitars and “Sons of God, Hear His Holy Word” (a most un-PC hymn today). My geographical parish church is 5 miles from my house. I have driven 25 miles for over 25 years to attend a reverent NO parish. I’m not the only one. We went from 200 individual parishoners in 1983 to over 2,500 registered families today. We must be doing something right - including singing traditional Catholic hymns, Gregorian Chant, and Latin motets. But, what is one to do when one’s bishop puts the damper on things and merely “acknowledges” the Motu Proprio. We’ve got the choir, we’ve got the people, but we can’t pin our pastor down because he is obviously concerned about the bishop.
You might say it has been a yawn, but I believe that there is still a deep seated longing in my generation for a return to the reverence we knew as children. Don’t count us out.
