As you know, July 1st is the Feast of the Precious Blood in the pre-1969 calendar. Unfortunately, this is one of the "idea feasts" which didn’t make the "expert" cut in 1969 (and the highest-ranking victim of tinkeritis [good word] – I think it was a second-class feastday).
Happily, July 1st is a feria in the modern calendar, with only an optional memorial for Blessed Junipero Serra otherwise obligating the day. Thus, priests are free to use the votive mass of the Precious Blood which is found in the 2002 M.R. (not that I’ve ever really seen this done).
My question is the following: for those laity (or even obligated religious and clergy) who use the LOTH for daily prayer, is there a way to celebrate the Precious Blood? I notice in the Liturgia Horarum that there is an office for "Christ, Our Eternal High Priest." Would that be appropriate to use? It has many references to the Precious Blood of Our Lord. This "votive office" is also a good one to keep in mind for the Year for Priests, even if it’s only in the Latin editio typica.
The alternative, of course, is simply to pray the July 1st office in the extraordinary form.
Non-obliged lay people can do as they please, since they have no obligation to say the Office at all and they do so from devotion.
As for those who are obliged, I like the idea of "Christ the Eternal Priest", especially during this Year.
The feast of the Precious Blood is a fairly new feast for the Roman Calendar. It was observed in Spain in the 16th centur, brought to Rome by the great St. Gaspar del Bufalo and them placed on the universal calendar in 1849 by Pius IX.
I don’t see why one could not, on a feria, use another office.
