Even though Latin has dwindled to the brink of extinction, even with the Latin-speaking Catholic being an endangered species, we must remember that we have a patron saint of Latin!
Meet the young Monsignor Antonio Bacci (later Cardinal) of the Segreteria dei Brevi ai Principi (see 1917 Code of Canon Law, canon 264). He was, they say, the greatest Latin prodigy of the century.
Today, everyone stands awe-struck with the genius of Fr. Reginald Foster, who is the finest living Latinist (and also famous for his irascible stream of rhetoric). Foster was a member of the last generation of seminarian which was immersed in Latin morning, noon and night (he had fourteen years of Latin before he was ordained). But the upper echelons never listened to Foster's plea to save our Catholic tongue (our inheritance) and so we have a lot of work to do to bring Latin back into our Catholic families, and sacred rites.
Before Foster, there was Bacci. For many years Monsignor Bacci was the Segretario dei Brevi ai Principi (pro. litt. in forma brevi ad Principes Secretarius). In this capacity he had an ordinary audience with the Pope every first Friday of each month. His office was in the Apostolic Palace of the Vatican. He worked with a team of four (three were laymen) and they put everything into Latin through the 1930s, '40s, '50 and '60s.
In the 1990s the Latin Liturgy Association translated the autobiography of Card. Bacci into English and it was a fantastic read. So if you can get your hands on it, then please do. Also, in 1963 he had the fourth edition published (by Editrice Studium) of a Latin-Italian dictionary of modern words which he had put together which was entitled, LEXICON Vocabulorum Quae Difficilius Latine Redduntur.
"Until 1967, the office of the Latinists enjoyed its own distinctive title. It was known as Epistoles ad Princeps - Briefs to Princes. The titles were taken away in a fit of modernism, and scholars like Fr. Foster were listed by their minor official rank in the Annuario Pontificio, the Who's Who of the Vatican. The scholar who held the last title as chief composer of the Briefs to Princes is now over ninety years old. The man lives in retirement in an apartment behind the Vatican, and when he dies, the old title will expire with him. 'He's the Last of the Mohicans,' said Fr. Foster, with an unerring instinct for the least apt comparison, a sign that thirty years in Rome have not touched him profoundly."
