What did our Holy Father say?; from Pope Benedict XVI on Sacred Music

Active Participation
Wherever an exaggerated concept of "community" predominates, a concept which is (as we have already seen) completely unrealistic precisely in a highly mobile society such as ours, there only the priest and the congregation can be acknowledged as legitimate executors or performers of liturgical song. Today, practically everyone can see through the primitive activism and the insipid pedagogic rationalism of such a position which is why it is now asserted so seldom. The fact that the schola and the choir can also contribute to the whole picture, is scarcely denied any more, even among those who erroneously interpret the council's phrase about "active participation" as meaning external activism. ("In the Presence of the Angels..." Adoremus Bulletin, Vol. 2, Nos. 6-8, Oct-Dec. 1996).

Silence
We are realizing more and more clearly that silence is part of the liturgy. We respond, by singing and praying, to the God who addresses us, but the greater mystery, surpassing all words, summons us to silence. It must, of course, be a silence with content, not just the absence of speech and action. We should expect the liturgy to give us a positive stillness that will restore us. Such stillness will not be just a pause, in which a thousand thoughts and desires assault us, but a time of recollection, giving us an inward peace, allowing us to draw breath and rediscover the one thing necessary, which we have forgotten. That is why silence cannot be simply “made”, organized as if it were one activity among many. It is no accident that on all sides people are seeking techniques of meditation, a spirituality for emptying the mind. One of man’s deepest needs is making its presence felt, a need that is manifestly not being met in our present form of the liturgy. For silence to be fruitful, as we have already said, it must not be just a pause in the action of the liturgy. No, it must be an integral part of the liturgical event.

Popular and Rock Music
On the one hand, there is pop music, which is certainly no longer supported by the people in the ancient sense (populus). It is aimed at the phenomenon of the masses, is industrially produced, and ultimately has to be described as a cult of the banal. “Rock”, on the other hand, is the expression of elemental passions, and at rock festivals it assumes a cultic character, a form of worship, in fact, in opposition to Christian worship. People are, so to speak, released from themselves by the experience of being part of a crowd and by the emotional shock of rhythm, noise, and special lighting effects. However, in the ecstasy of having all their defenses torn down, the participants sink, as it were, beneath the elemental force of the universe. The music of the Holy Spirit’s sober ine­briation seems to have little chance when self has become a prison, the mind is a shackle, and breaking out from both appears as a true promise of redemption that can be tasted at least for a few moments. [The Spirit of the Liturgy, (SF, CA: Ignatius, 2000), p 148]

Sacred vs. Performance
Whether it is Bach or Mozart that we hear in church, we have a sense in either case of what Gloria Dei, the glory of God, means. The mystery of infinite beauty is there and enables us to ex­perience the presence of God more truly and vividly than in many sermons. But there are already signs of danger to come. Subjective experience and passion are still held in check by the order of the musical universe, reflecting as it does the order of the divine creation itself. But there is already the threat of invasion by the virtuoso mentality, the vanity of technique, which is no longer the servant of the whole but wants to push itself to the fore. During the nineteenth century, the century of self-emancipating subjectivity, this led in many places to the obscuring of the sacred by the operatic. The dangers that had forced the Council of Trent to intervene were back again. In similar fashion, Pope Pius X tried to remove the operatic element from the liturgy and declared Gregorian chant and the great polyphony of the age of the Catholic Reformation (of which Palestrina was the outstanding representative) to be the standard for liturgical music. A clear distinction was made between liturgical music and religious music in general, just as visual art in the liturgy has to conform to different standards from those employed in religious art in general. Art in the liturgy has a very specific responsibility, and precisely as such does it serve as a wellspring of culture, which in the final analysis owes its existence to cult. [The Spirit of the Liturgy, (SF, CA: Ignatius, 2000), pp. 148]
Not every kind of music can have a place in Christian worship. It has its standards, and that standard is the Lo­gos. If we want to know whom we are dealing with, the Holy Spirit or the unholy spirit, we have to remember that it is the Holy Spirit who moves us to say, “Jesus is Lord” (~Cor 12:3). The Holy Spirit leads us to the Logos, and he leads us to a music that serves the Logos as a sign of the sursum corda, the lifting up of the human heart. Does it integrate man by drawing him to what is above, or does it cause his disintegration into formless intoxication or mere sensuality? That is the criterion for a music in harmony with logos, a form of that logike latreia (reasonable, logos-worthy worship)… [The Spirit of the Liturgy, (SF, CA: Ignatius, 2000), p. 151]

Latin in Liturgy
I would be in favor of a new openness toward the use of Latin. Latin in the Mass has come meanwhile to look to us like a fall from grace. So that, in any case, communication is ruled out that is very necessary in areas of mixed culture... Let's think of tourist centers, where it would be lovely for people to recognize each other in something they have in common. So we ought to keep such things alive and present. If even in the great liturgical celebrations in Rome, no one can sing the Kyrie or the Sanctus any more, no one knows what Gloria means, then a cultural loss has become a loss of what we share in common. To that extent I should say that the Liturgy of the Word should always be in the mother tongue, but there ought nonetheless to be a basic stock of Latin elements that would bind us together.
