The centennial of the Apostolic Constitution Divino Afflatu, of Pope Saint Pius X, on the reform of the rubrics and arrangement of the Roman Breviary and on some matters related to the Roman Missal, is coming up on November 1st, All Saints', as our readers are able to notice in our commemorative header above. We plan some posts to mark this major liturgical occasion, but we are always open to contributions of all kinds on this consequential accomplishment of the Sarto pontificate.
