Chirograph of the Supreme Pontiff for the Centenary of the Motu Proprio 'Tra Le Sollecitundini' on Sacred Music
Written by St. John Paul II
As one would expect in a document commemorating the anniversary of another, St. John Paul II pays tribute to Pius X and other 20th century pontiffs who devoted attention "to this delicate sector." He offers a ceremonial affirmation of principals articulated in Tra Le Sollecitudini, but then notes that the fathers of the Second Vatican Council reasserted earlier principles "with a view to their application in the changed conditions of the times."
