Q. 1. Why is it that the Catholic Church uses Latin as its official language?
A. 1. Latin became the official language of the Catholic Church because when the Church was founded in the day of the Roman Empire, the language spoken throughout the Empire was Latin.
During the 18th and 19th centuries, Latin remained the language of the educated classes. Furthermore, by having an official language throughout the centuries, this permitted the bishops of the entire world to communicate with one another, although the languages of their lands were different. Latin kept the Church united.
