It also turns out that most official Church documents are not authored in Latin at all. Often, the "reference language" for Papal documents will be Italian, or another common language. Spanish is quite popular, of course, with the (ethnic Italian) Argentinian Pope Francis. It was, of course, quite fitting that Pope Pius XI should write Mit brennender Sorge entirely in German, considering his audience at the time. However, there are two very important holdouts in this regard, and those are the sacred liturgy and Canon Law. The only definitive editions of the Roman Missal and the Code of Canon Law are the originals in Latin. Every other edition is translated from these master editions. It's a very important thing to remember for canonists attempting to interpret the law, that they should keep in mind Latin words, phrasing, and the implied meanings, not whatever sloppy English has been applied for a mass-market publication.
