Laudatur Iesus Christus.
The Holy Spirit and the Conciliar Fathers of Trent taught:
They shall also banish from churches all those kinds of music, in which, whether by the organ, or in the singing, there is mixed up any thing lascivious or impure; as also all secular actions; vain and therefore profane conversations, all walking about, noise, and clamour, that so the house of God may be seen to be, and may be called, truly a house of prayer. (Council of Trent, Session XXII, 17 September 1562, Decree Concerning the Things to be Observed, and to be Avoided, in the Celebration of Mass.)
I submit that this has not been changed by any subsequent teaching and that it is among the things set out at Trent which remain “intact” in the teachings of the Holy Spirit and the Conciliar Fathers of the Second Vatican Council, (see Vatican II, Sacrosanctum Concilium, (1963), 55 and footnotes 20 and 34). The section of the General Instruction of the Roman Missal, quoted earlier in this discussion, seems to confirm this understanding of the matter (see GIRM 45).
I also think of “". . the LORD is in his holy temple; silence before Him, all the earth!" (Habakkuk 2:20); and,
Christ’s command, implemented by the Council of Trent: “It is written: ‘My house shall be a house of prayer,’ . . .” (Matthew 21:13.)
Spiritus Sapientiae nobiscum.
