I see what you’re saying, but as somebody who lived through both, I think you’re mistaken in assigning the greater impact to the recent changes.
A. The changes of 2011, in and of themselves, were not really all that drastic as changes (some different words, but no adjustment to the Mass format, postures, positions, etc.). And for the majority of those Catholics, even the ones who attended sporadically, the reasons for and the preparations went on for months in advance. Plus you have the Internet and far more availability to get information. And you have a population which is used to change in every aspect of life.
B. The changes in the 1960s were far more drastic. Ever been to a TLM? If not, go to You Tube and pull one up. Imagine that, just as the 2011 Catholics had been exposed to the “old translation’ for 40 years, you’re a 1960s Catholic who has had that TLM as your experience (and to a far greater extent than the 'Christmas and Easter” Catholics of 2011, or even the ‘average’ Catholic who by no means is a weekly Church-goer).
Which group underwent the most difficulty in adjusting to 'change"?
Again, having been through both, I can tell you that in many cases it is not the change in a handful of words that is causing angst among those who call for ‘the old translation before 2011’. No, it isn’t that change. Most of these people thrive on change. They love it when there are ‘new things’ at liturgy. It keeps them actively participating, don’t you know.
No, what they object to is that the ‘new translation’ keeps change from occurring.
Father Mc Adlib could poof around prior to 2011 and nobody cared because Everybody EXPECTED Father to have his ‘little touches’.
But once 2011 rolled into play, everybody was prepared for what they had been told would be heard. And, unless Father is extremely disobedient (sadly, some may be), Father was no longer doing ‘the personal touch’. And THAT is what many in the pews are missing. They will fixate on a ‘weird word’, but the main complaint is that instead of Father doing “St TouchyFeely’s Mass whereby we all hear a slant about social justice or New Age Journeys or ecumenoplasty” we hear, or are supposed to hear, a Mass that isn’t all about ‘our personal ways and ideas’. And many don’t like THAT. And that, IMO, is what is being addressed in the new MP from the Vatican, God help us, because I think that is very poorly reasoned though I’m certain it is with the best intentions. And one knows what ‘best intentions’ often result in paving. . .
