Final answer:
The ordinances of the Vatican are typically published in Latin, following the Catholic Church's long-standing tradition of using Latin for official documents, liturgy, and legal communication.
Step-by-step explanation:
The language of publication for the ordinances of the Vatican is typically Latin, in keeping with the tradition of the Roman Catholic Church. Latin has been the lingua franca of the Church since the Early Middle Ages, serving as the language of liturgy, law, and educated communication across Europe, as reflected in documents such as the Vulgate, the Liber Sextus Decretalium, and the Decretales Gregorii IX, which are part of the Corpus Iuris Canonici.
This tradition contrasts with the diverse linguistic approaches of the Eastern churches where Greek, and other local languages, played a more prominent role in ecclesiastical matters.
Even as Latin faded from common speech, it continued to be used as the language of the educated elite and church officials, enabling correspondence and scholarly discourse among various regions of Europe.
