An admirable priest called Fr Harrison has recently asked orthodox Catholics to revisit the Novus Ordo.
I offer some thoughts about what those who share Father's instincts might do so as to go just a little way to meet Traddy worshippers.
(1) Use only the First Eucharistic Prayer. Always. Even with the kiddies. Do this as your first matter of first principle. Even if you're trinating. The provision of alternatives was the main error of ... NOT Vatican II, where no such move was even hinted at, but of the corrupt use of their influence by those who subsequently got their grubby hands on the levers of power. Without this gross mistake, other changes might, just possibly, have been just about tolerable. (After all, the Dominicans ... and others ... used a shorter Confiteor ... had shorter and different Offertory prayers ... )
(2) Sort out your Sacristy. If it goes back to before the 1970s, it has what used to be a 'vesting' surface, where vestments used to be laid out before Mass, layer upon layer, Chasuble at the bottom, amice on top, in a customary pattern. This surface is now covered with things which innumerable people have dumped there over the decades because they couldn't think of anywhere else to dump them. Often things like ten-year-old gas bills. Shift the clobber all away, and restore this surface to its proper use. And put up the traditional Latin Vesting Prayers where you will be able to see them and say them while vesting. There are important matters of culture in this stage; and in my next one:
(3) Institute a custom of quiet recollection in the Sacristy before Mass.
(4) Adopt EF customs such as holding thumb and forefinger together to avoid scattering crumbs of the Most Holy; arrange things on the corporal as they are in the Old Rite; follow the Old Rite in details like where to put the Missal ... use of pall, burse, and veil, etc... the Maniple is not exactly forbidden ... then there is the matter of incense ...
(5) Desist from saying the dreary little Novus Ordo Offertory Prayers aloud. In fact, the rubrics themselves give no justification for always saying them so as to be heard. At best, this is optional and indeed sometimes not permitted. (Look at the GIRM if you don't believe me.) Say them silently ... and vide (7) infra ...
(6) Put a Crucifix on the middle of the Altar, even if it comes between you and the people. Pope Benedict commended this, and Pope Francis has, actually, continued it. You could start off with a little crucifix and gradually work up to a nice big one. Christ died for us.
Everything so far is boringly legal. At this point, we enter the exciting area 'Not Quite So Strictly Legal'.
(7) Instead of the Novus Ordo Offertory Prayers, use the old ones. Say them (secreto) in Latin. You will probably need to use a central Altar Card, propped up against the crucifix. Or perhaps you will glue a new page, photocopied from an old Missal, into your Novus Altar Missal. If the People notice that your lips are inaudibly moving, it will be a valuable lesson to them that the main Person a Eucharistic celebrant is addressing is God, not them.
(8) Use the Trinity Sunday Preface on all Green Sundays.
(9) Genuflect more. You know when!
(10) Have a think about how to get away with eliminating the 'Acclamation' after the Consecration of the Chalice ... a nasty unRoman orientalising interpolation ... a deplorable distraction (in the Western Rite) from the Great Presence and the August Oblation ... . Not easy ... but it would be a valuable coup if you could manage it.
You will notice that I have not mentioned the direction which the Celebrant faces. This is because I think it is far more important to do the ten things I have listed. Especially considering the problems that particular change could cause you with parochial malcontents. As I am sure you are aware, even the Missal of S Pius V gives full instructions for celebrating facing the people, as if there is no particular significance in which direction is used. If S Pius V didn't care, why should you make your life a misery for it?
Because I want to concentrate on the other ten matters, I will not publish comments on that last paragraph!
