Redemptionis Sacramentum

[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”.[133]

[57.] It is the right of the community of Christ’s faithful that especially in the Sunday celebration there should customarily be true and suitable sacred music, and that there should always be an altar, vestments and sacred linens that are dignified, proper, and clean, in accordance with the norms.
