I don’t think there’s much good about the Novus Ordo, but what I did like was the 1965 Missal, which was a translation into the vernacular of the 1962 Missal with a few changes (the Last Gospel had been removed, for example). It was used from 1965 until the Novus Ordo came into use in 1970.
Bring that back and I don’t think there’s a Catholic in the world who would object (except for extremists at either end of the spectrum). It would be a great compromise and, better yet, the translations into most major languages already exist.
Perhaps a few parts of the ordinary in Latin or Greek could be kept in those languages: the Kyrie, the Agnus Dei, the Sanctus, etc. Most people know these things or could learn them easily, and it would tie us to our liturgical and cultural past.
The Old Calendar, with the addition of the new saints, should also be brought back. We need the the different liturgical seasons clearly delimited by the traditional feasts, the Rogation Days, etc.
One of the big problems now in encouraging the 1962 Missal is simply that most current priests don’t have the time (and alas, some don’t have the ability) to learn Latin, so even those who would like to do it, unless they are so devoted they join an order dedicated to nothing but that, can’t realistically be expected to celebrate it.
And the old 12 minute dead-silent or mumbled low mass, which unfortunately was the standard in the US, was an abuse that we don’t want to go back to, and one of the things that made people willing to accept the Novus Ordo.
The new translations are basically all the 1965, 1962 missal. As our priest was discussing the changes, another lady and I were following along in her husband’s old missal. The wording was almost identical between the new translations and the older missal.
