Many people are asking how Dan Schutte’s Mass of Christ the Savior obtained approval. The Gloria does the usual trick of mangling the text into an antiphon/response structure but, even more alarming, it changes the liturgical text: “Glory to God in the highest / and on earth / peace on earth / peace to people of good will.”
At the very least, singing the wrong text doesn’t seem like a good way to learn a new text.
