Latin

[[File:Wallsend platfom 2 02.jpg|thumb|The signs at [[Wallsend Metro station]] are in English and Latin, as a tribute to [[Wallsend]]'s role as one of the outposts of the [[Roman Empire]], as the eastern end of [[Hadrian's Wall]] (hence the name) at [[Segedunum]].]]

The largest organisation that retains Latin in official and quasi-official contexts is the [[Catholic Church]]. The Catholic Church required that Mass be carried out in Latin until the Second Vatican Council of 1962–1965, which permitted the use of the [[vernacular language|vernacular]]. Latin remains the language of the [[Roman Rite]]. The [[Tridentine Mass]] (also known as the Extraordinary Form or Traditional Latin Mass) is celebrated in Latin. Although the [[Mass of Paul VI]] (also known as the Ordinary Form or the Novus Ordo) is usually celebrated in the local vernacular language, it can be and often is said in Latin, in part or in whole, especially at multilingual gatherings. It is the official language of the [[Holy See]], the primary language of its [[public journal]], the {{lang|la|[[Acta Apostolicae Sedis]]}}, and the working language of the [[Roman Rota]]. [[Vatican City]] is also home to the world's only [[automatic teller machine]] that gives instructions in Latin.<ref>{{cite news |last=Moore |first=Malcolm |title=Pope's Latinist pronounces death of a language |url=https://www.telegraph.co.uk/news/worldnews/1540843/Popes-Latinist-pronounces-death-of-a-language.html |work=[[The Daily Telegraph]] |date=28 January 2007|archive-url=https://web.archive.org/web/20090826081734/https://www.telegraph.co.uk/news/worldnews/1540843/Popes-Latinist-pronounces-death-of-a-language.html |archive-date=26 August 2009 |url-status=live }}</ref> In the [[pontifical university|pontifical universities]] postgraduate courses of [[Canon law]] are taught in Latin, and papers are written in the same language.

There are a small number of Latin services held in the Anglican church. These include an annual service in Oxford, delivered with a Latin sermon; a relic from the period when Latin was the normal spoken language of the university.<ref>{{cite web |title=University Sermons |url=https://www.universitychurch.ox.ac.uk/content/university-sermons |website=University Church Oxford |access-date=25 March 2023}}</ref>

[[File:Former logo of the European Council and Council of the European Union (2009).svg|thumb|right|The polyglot [[European Union]] has adopted Latin names in the logos of some of its institutions for the sake of linguistic compromise, an "ecumenical nationalism" common to most of the continent and as a sign of the continent's heritage (such as the [[Council of the European Union|EU Council]]: {{lang|la|Consilium}}).]]
