Pope Francis has died

In 2021, during a visit to the Greek island of Mytilene, Pope Francis delivered one of the finest speeches I've ever read:

> This great basin of water, the cradle of so many civilizations, now looks like a mirror of death. Let us not let our sea (mare nostrum) be transformed into a desolate sea of death (mare mortuum). Let us not allow this place of encounter to become a theatre of conflict. Let us not permit this “sea of memories” to be transformed into a “sea of forgetfulness”. Please brothers and sisters, let us stop this shipwreck of civilization!

> We are in the age of walls and barbed wire. To be sure, we can appreciate people’s fears and insecurities, the difficulties and dangers involved, and the general sense of fatigue and frustration, exacerbated by the economic and pandemic crises. Yet problems are not resolved and coexistence improved by building walls higher, but by joining forces to care for others according to the concrete possibilities of each and in respect for the law, always giving primacy to the inalienable value of the life of every human being

I had no idea anyone still used the term “mare nostrum”. I believe it began to be used during the Roman Empire when the Romans had conquered all lands surrounding the Mediterranean. Back then, the term meant the sea belonged to them and no one else. That meaning no longer applies in the modern day, so using it today would mean “we all share this” rather than the original meaning. His use of the term was a clever way to invoke shared history.

You are correct that most people do not use the term any more. But the Pope isn't like most people. It's an informal requirement that the Pope be able to speak Latin and Italian is commonly used in the Vatican (being surrounded by Italy probably has something to do with that). Even though Francis was not as fluent as his predecessors in Latin and Italian, he certainly understood it better than most and his speechwriters probably were probably proficient in Latin.
