…I see nothing inherently superior with older music.
But the thing is, the Church does see “older music” as inherently superior to the “modern” dreck that happens in most parishes today. Not because it is older, but because it more fully fulfills the requirements of sacred music in the liturgy. In fact, the Church has been adamant about this fact:
*“Gregorian chant…should be given pride of place in liturgical services. But other kinds of sacred music, especially polyphony, are by no means excluded from liturgical celebrations…”
“You, teachers and students, are asked to make the most of your artistic gifts, maintaining and furthering the study and practice of music and song in the forms and with the instruments privileged by the Second Vatican Council: Gregorian chant, sacred polyphony and the organ.”
“With regard to liturgical music compositions, I make my own the “general law” that Saint Pius X formulated in these terms: ‘A composition for Church is sacred and liturgical insofar as it approaches Gregorian melody in flow, in inspiration, and in flavor, and so much less is it worthy of the temple insomuch as it is recognized as departing from that supreme model’.”
“Classic Polyphony agrees admirably with Gregorian Chant, the supreme model of all sacred music, and hence it has been found worthy of a place side by side with Gregorian Chant”
“An authentic updating of sacred music can take place only in the lineage of the great tradition of the past, of Gregorian chant and sacred polyphony…”
“In the West, in the form of Gregorian chant, the inherited tradition of psalm-singing was developed to a new sublimity and purity, which set a permanent standard for sacred music, music for the liturgy of the Church.”*
