Okay, here’s another. As I’ve said, to my knowledge these are rulings for which there is presently no English translation available on the internet. This one is 14 (1978), 303–304, n. 6Notitiae:
- In concelebrationibus peragendis, modi differentes inveniuntur in sequentibus actionibus:
a) Interdum, probe distinguitur vox celebrantis principalis, dum concelebrantes submissa seu modesta voce Precem eucharisticam proferunt. Alibi, e contra, quoddam quasi certamen elatarum vocum auditur, dum unusquisque ceteros quasi superare contendit.
*b) * In epiclesi peragenda ante consecrationem, non omnes celebrantes manus protendunt erga oblata ad invocandam actionem Sancti Spiritus, dum diligentissimi sunt in protendenda manu durante consecratione.
c) In ipsa epiclesi nonnulli manum retrahunt simul ac celebrans principalis signaverit super oblata, dum alii porrectas tenent manus donec textus epiclesis finiatur.
Quinam modus sequendus est?
Ad optimum secernendum in hac varietate, satis erit perpendere naturam functionum, quae peraguntur ab unoquoque, et naturam gestuum ipsis respondentium.
a) Iuxta IGMR 170, coetus fidelium distincte percipere debet vocem praesidentis: quod obtineri potest mediante microphonio sensibili et bene collocato, et praesertim ex modestia vocum concelebrantium (submissa voce). Alioquin, in secundo casu considerato, unitas tenoris et rythmi ad intellegendum textum ex parte coetus obtineri nequit.
b) Illud satis curiosum est, quod Missalis normae contemplantur casum plane oppositum quam qui supra consideratur: durante epiclesi consecrationis omnes celebrantes debent imponere manus super oblata (IGMR 174a, 180a, 184a, 188a: manibus ad oblata extensis) in invocanda actione Spiritus sanctificantis; dum consecratione durante, concelebrantes tendunt manum dexteram ad panem et calicem, si opportunum videtur (IGMR 174c, 180c, 184c, 188c): idque dum recitant verba Domini, scilicet usque ad « Hoc facite in meam commemorationem » inclusive.
c) Actus imponendi manus debet comitari verba precis. Hac de causa rubricae Ordinis Missae (90, 103, 110, 119) indicant finem huius actus per verba: iungit manus.
6. In carrying out concelebrations, different methods are found in the following actions:
a) Sometimes, the voice of the principal celebrant is properly distinguished, when the concelebrants offer the Eucharistic Prayer with a lowered or modest voice. Otherwise, by contrast, a certain, almost struggle of raised voices is heard, when each one vies as though to defeat the others.
b) In carrying out the epiclesis before the consecration, not all celebrants hold forward their hands toward the gifts to invoke the action of the Holy Spirit, while they are most diligent in holding out a hand during the consecration.
c) In the epiclesis itself some draw back their hands at the same time as the principal celebrant signs over the gifts, which others hold their hands extended until the text of the epiclesis is finished.
Which method is to be followed?
For best separating out this variety, it will be enough to examine the nature of the functions which are carried out by each one, and the nature of the gestures corresponding to them.
a) In accord with GIRM 170, the assembly of the faithful ought to perceive distinctly the voice of the presider: which can be accomplished by means of a microphone well and sensibly placed, and chiefly through the modesty of the voices of the concelebrants (with lowered voice). But, in the second case considered, unity of tenor and rhythm for the understanding of the text on the part of the assembly cannot be obtained.
b) It is fairly curious that the norms of the Missal contemplate a case plainly opposed to that which is considered above: during the epiclesis of the consecration, all celebrants ought to impose their hands over the gifts (GIRM 174a, 180a, 184a, 188a: with hands extended to the gifts) in invoking the action of the sanctifying Spirit; while during the consecration, the concelebrants hold their right hands toward the bread and chalice, if it seems opportune (GIRM 174c, 180c, 184c, 188c): and [they do] that while they recite the words of the Lord, to wit, up to “Do this in memory of me,” inclusive.
c) The act of imposing hands ought to accompany the words of the prayer. For this reason the rubrics of the Order of Mass (90, 103, 110, 119) indicate the end of this act by the words: he joins his hands.
