Wow - didn’t notice that part; I watched the first few minutes and then began to type my response for CAF! That passage from scripture “We must diminish and Christ increase” comes to mind, but for the wrong reasons. I just can’t get my head around the fact that the priest and the people are (or rather should be) witnessing the wondrous re-presentation of the Sacrifice of Calvary, but instead the most sacred liturgy and prayer of the Church is turned into a concert performance.
To clarify what I wasn’t able to earlier regarding musical instruments during the Eucharistic Prayer, I quote from the oft-quoted Redemtionis Sacramentum:
'[52.] The proclamation of the Eucharistic Prayer, which by its very nature is the climax of the whole celebration, is proper to the Priest by virtue of his Ordination. It is therefore an abuse to proffer it in such a way that some parts of the Eucharistic Prayer are recited by a Deacon, a lay minister, or by an individual member of the faithful, or by all members of the faithful together. The Eucharistic Prayer, then, is to be recited by the Priest alone in full.[131]
[53.] While the Priest proclaims the Eucharistic Prayer “there should be no other prayers or singing, and the organ or other musical instruments should be silent”,[132] except for the people’s acclamations that have been duly approved, as described below.
[54.] The people, however, are always involved actively and never merely passively: for they “silently join themselves with the Priest in faith, as well as in their interventions during the course of the Eucharistic Prayer as prescribed, namely in the responses in the Preface dialogue, the Sanctus, the acclamation after the consecration and the “Amen” after the final doxology, and in other acclamations approved by the Conference of Bishops with the recognitio of the Holy See”.’
Also, regarding the fact that the priest does not appear to be using a prescribed text for the Eucharistic Prayer, the previous paragraph of RS says:
“[51.] Only those Eucharistic Prayers are to be used which are found in the Roman Missal or are legitimately approved by the Apostolic See, and according to the manner and the terms set forth by it. “It is not to be tolerated that some Priests take upon themselves the right to compose their own Eucharistic Prayers”[129] or to change the same texts approved by the Church, or to introduce others composed by private individuals.”
So the Church’s position is abundantly clear. I hope someone notified the bishop.
