The Holy Father, being older than “the hippie generation” as you call it, likely won’t be here when they are all gone. I also think it’s a mistake to believe a return to the Mass of 50 years ago is going to solve so many problems.
Many seminaries don’t even teach Latin anymore. Recently, in a discussion with several younger priests in our diocese, all ordained between 3-5 years ago, this topic came up. Only one of them wanted to see any regular use of a Latin Mass, and every one of them favored a vernacular Mass. So I’m not so sure about this idea of a younger generation of priests so willing to jump back into 1960s worship.
I think there is a place for the Latin Mass, I respect people’s viewpoint that they find it a more beautiful expression of the Mass. Personally, having grown up in it and served those Masses, I don’t find it more beautiful, only different. I think there is ample room for the Mass in both forms.
