Could the Church's Understanding of the Primacy of Gregorian Chant Ever Change?
The Roman Catholic Church officially holds that Gregorian chant should have “pride of place” in the Roman liturgy. Though this position was reaffirmed at the last ecumenical council, we can all agree that it is not a teaching of apostolic origin and is not a de fide dogmatic definition. How weighty is this official position? Could it ever change? Should it? There is good reason to think that it both could and should.
