The subject is the Extraordinary Form in China.
FIUV's website explains "Because of the unique recent history of the Catholic Church in China, the Extraordinary Form has continued to be said alongside the Ordinary Form. The paper argues that the affinity between classical Chinese culture, and notably Confucianism, and the Faith, continues to be relevant in the context of the Extraordinary Form, as the values of continuity, discipline and respect for the sacred continue to be valued, and needed, in the China of today. The Extraordinary Form is moreover helpful in many of the difficulties facing the Church in China today, including linguistic pluralism, poor catechesis, and liturgical indiscipline. . . . . ."
Dr Shaw writes "While other parts of the world have been holding our attention in recent weeks, it is salutary to remind ourselves of the heroism of China's many faithful Catholics, who have faced persecution of one form or another for so many decades. Despite this, the Church in China is growing steadily, and her needs should be considered carefully.
This paper draws attention to a number of important factors in the Church's situation in China which indicate the importance of the ancient liturgy. First, the fact that it has actually survived, and continues to be celebrated widely in China: the Ordinary Form was not introduced into mainland China until the 1980s. Second, that the celebration of the liturgy in the vernacular in China is particularly difficult, since large populations speak languages, such as Cantonese, which do not have a written form into which the liturgy could be translated, and are therefore offered a 'vernacular' liturgy which can be entirely incomprehensible. Third, as the ancient liturgy represents the values of reverence, continuity, and self-restraint which are both characteristic of classical Chinese culture, and are desperately needed in China today, in the context of the country's rapid economic development and urbanisation."
