"Impelled by the weightiest of reasons, we are fully determined to restore Latin to its position of honor, and to do all We can to promote its study and use. The employment of Latin has recently been contested in many quarters, and many are asking what the mind of the Apostolic See is in this matter. We have therefore decided to issue the timely directives contained in this document, so as to ensure that the ancient and uninterrupted use of Latin be maintained and, where necessary, restored.”
— Pope John XXIII (22 February 1962)
