Dr Shaw, on the LMS website, draws our attention to a fine document (Sacrificium laudis) of B Paul VI in which the Blessed Pope makes, in 1966, a strong, almost hysterical, plea for the retention of Latin in Religious Communities. The website provides links to Latin and Italian versions, and a translation into English by the learned Fr Crean, to whom the movement for renewal within Tradition owes so much.
Latinists may enjoy reading the Latin text and totting up the typos and errors.
It's almost as if the text itself is designed to highlight the magnitude of the problem!!
