We host the Deanery (a group of several N.O. parishes) procession, and have always used the EF rubrics. No one has ever complained!

I recently parked a couple of 4-altar links at CPDL Category talk:Corpus Christi.

Yes

If you're using the EF rubrics.... no. What isn't explicitly permitted is forbidden, if I recall, is the principle of the rubrics. Otherwise, the fact that the rubrics don't forbid the preaching of heresy could be read to permit exactly such a thing.

If you're trying to use OF rubrics, I understand that they don't exist. (There may be more than one reason for this.)

Even in EF... its not impossible- case in hand, monasteries of women-
Normally when a monastery observes Papal Enclosure or Constitutional Enclosure, only clergy are permitted inside the enclosure for such rites, thus, the Nuns have to do what the altar server would normally do.

Monastery liturgist, your point is well taken. When there isn't any way for it to be done by the rubrics, a niche exists so long as it is possible.... so a priest is still necessary for the sacraments.

In Eastern Kentucky and Tennessee there aren't many Catholic parishes within walking distance, to be sure, but here in the diocese of San Jose, we could have a procession in many parts of the more urban areas. I haven't measured it, but there are 4 parishes within about 2 or 3 miles of each other in the heart of downtown San Jose, and one of them is the Cathedral.

Processions don’t much happen in this diocese, for any purpose, but the distance between parishes isn’t the reason.

At St. Adelaide's in Peabody, MA, the procession made a circuit around the church, starting by singing Pange Lingua (but not Tantum Ergo). With a temporary station at the outdoor shrine for our Lady, it paused and the priest gave benediction there (Tantum Ergo was sung). The procession paused briefly by a statue of the Sacred Heart for a second benediction (though without a station), and then returned to the church for the third benediction (Tantum Ergo was sung again). The schola of four voices led conventional chants and hymns: O Salutaris, "Jesus, My Lord, My God, My All", Adoro Te. It was good to hear voices in the congregation singing some of the chants at Mass today: e.g, parts of the Asperges and Credo. Here's how the shrine of our Lady looks without any additions:

In other news, I'm pleased to report that our parish held its first eucharistic procession in years. Based on my discussion with one life-long parishioner, it sounds like it has actually been decades since it was done, although the canopy we found couldn't have been quite that old. At any rate, it's been at least 2 or 3 pastors since it last occurred and it was a tremendous success. We were even granted permission from the city to close the two adjacent streets behind the church to allow us to process around our block in peace. It was truly lovely. The procession was led by some of our recent first-communicants dropping rose pedals in the street. We revived the old canopy and it was carried by Knights. There were four "altars" set up along the route as stopping points for all to kneel and pray. We chanted various things between each station. I'd say there were probably about 250+ people in procession? (Including many attendees of other mass times who showed up expressly to participate in the procession.) I am so grateful it took place (and that my 5yo son got to finally witness a procession).

Our procession went from the main church into the cloister garden, then the procession of the people waited outside of the monastery gates where they processed around the monastery outer-walls and into the church again with the hymn "Christus Vincit" and a total of 7 benedictions (4 in the cloister, 2 outside, final inside) with Solemn Vespers... all in all I think it went okay thanks be to God. The cloister always involves and adventure in the liturgy. Thanks for all the help.

We managed a procession for the External Solemnity, but not for the feast itself.

We're having more processions, and more nocturnal adoration and... we're seeing a growth in our parish.

I attended Corpus Christi Mass in my local Melkite Catholic parish. Some Melkite churches have kept this feast, in a very good way (they composed new texts instead of relying on those from the Latin Church). After Mass, we received a Benediction of the Most Holy Sacrament, in the Byzantine use.
