Benedict XVI, the first Pope since the Middle Ages to resign his office, is also the first pontiff to maintain a Twitter feed—using the Latin handle @Pontifex. Benedict announced his decision Monday, not with a tweet, but in a speech delivered in Latin to cardinals of the Catholic Church. It now falls to the next Pope to make its global communications equal to its Latin.
But my son tweets that Benedict actually made a grammatical error in his Latin, a sign of his age perhaps. --ts
