In my most humble opinion, I think, if only, if only, if only, that those who manufactured the 1970's Roman Missal with a theology that could be manipulated by so many had insisted that the position of the priest at the altar not change, so much would be different today.
There would have been no recovations of beautiful churches with their magnificent high altars destroyed or ignored. There would have been more peace and joy in parishes where there would have been no waste of time or resources convincing people that the new liturgy need new wine skins, so to speak.
New churches would not look as horrible as some of the 70's, 80's and 90's concoctions.
Catholic liturgical spirituality would not have been destroyed. over night.
So, when we watch Bishop Morlino's version of the Ordinary Form Requiem celebrated ad orientem, I can only imagine bishops like Cardinal Cupich and other liturgical visionaries rolling their eyes.
