[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.
[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”, 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”.
