Catholic Sacred Music vs Secular Music

Is anyone going to accuse the Roman Catholic Church of being too “ethnic” or failing to “adapt to Western culture”?!

“Those instruments which are, by common opinion and use, suitable for secular music only, are to be altogether prohibited from every liturgical celebration and from popular devotions.”
- Musicam Sacram, Consilium for the Implementation of the Constitution on the Liturgy and the Sacred Congregation of Rites, 1967
