Yes, Virginia, there is not only a Santa Claus, but these two photos are two examples of the two forms of the Latin Rite Mass, the Extraordinary Form and the Ordinary Form. Can you tell the difference?
In terms of the two forms of the one Roman Rite, although, there are other rites, like the Ordinariate's Rite, and Pope Francis stated on Monday that The Zairean Rite is a “promising model” for the Amazon.
And of course there are other rites in the Latin Rite, such as the Ambrosian and Dominican Rites.
Because of its rigidity in terms of language and rubrics, I doubt the Extraordinary Form of the Mass could be inculturated, although a vernacular hymn could accompany the procession at the beginning of Mass prior to the chanting of the Introit and the same with the recessional. I think too in addition to the Offertory and Communion antiphons, an inculturated anthem could be sung in whatever acceptable idiom, be it Gospel or otherwise. But that would be about it unless others have suggestions.
Also, some SSPX parishes in France and even our Cathedral Basilica in Savannah allow a layman to read the Epistle and Gospel after the priest introduces them with the Latin salutation and first few words of the readings and then goes silent as he reads the Latin Text while simultaneously the layman reads both the Epistle and Gospel in the vernacular from the ambo. It doesn't take a leap to allow these to been done in the vernacular instead of Latin and at the ambo by a lay reader for the Epistle and the priest or deacon for the Gospel.
But the Ordinary Form can be so easily molded to inculturation as well as parish adaptations, that almost anything could go.
But that's not the point of my post. This is it:
What about adding to the Ordinary Form aspects of the Extraordinary Form. Certainly an all Latin OF Mass is foreseen as it is the official language of this Mass. In fact, I have an all Latin Ordinary Form Roman Missal.
But what about these customs associated with the EF Mass?
1. Remove the chasuble prior to preaching the homily and begin and end the homily with the Sign of the Cross. Currently as our Cathedral Basilica's EF Mass, the celebrant only removes the maniple placing it on the Missal prior to proceeding the to the ambo to preach the homily.
2. What about the use of the biretta? Could it be used for the procession, sitting for the readings, for the homily and at the recessional?
3. We know that ad orientem and kneeling at the altar railing is allowed but heavily depends on the position of the local bishop if he will allow it or not.
4. Could the EF's Asperges or Vidi Acquam be used as a prelude to the OF Mass?
5. Could the priest during the Eucharistic Prayer, any of them, and during the consecration bow slightly when he says, "and He gave you thanks..." and could there be double genuflections as in the Ordinaritate's Missal?
6. What else do you think is plausible with the hyper adaptability of the Ordinary Form, that bishops might allow?
