Pope Leo XIV Approves Historic Change of Official Vatican Documents' Drafting Language from Latin to Modern
Pope Leo XIV approved new regulations for the Roman Curia published on Nov. 24. One historic change is the drafting of Official Vatican documents in languages other than Latin. The document now regulates: Title XIII - LANGUAGES IN USE Art. 50
§1. The curial institutions will normally draft their acts in Latin or in another language.
§2. An office for the Latin language is established within the Secretariat of State, at the service of the Roman Curia.
§3. Care will be taken to ensure that the main documents intended for publication are translated into the most widely used languages today.

Another key development of the reforms is new employment directives that have been codified, mandating a six-day working week, fixed hours, 26 days of annual leave, limits on part-time work and bans on hiring relatives within the same office. Sick leave is to be closely monitored, and new evaluation systems will join responsibilities to measurable standards.
