The Pope tweeted in Latin for the first time on Sunday - drawing a blank response from many followers who don't speak the dead language, according to a Daily Mail report on news.com.au.
"Unitati christifidelium integre studentes quid iubet Dominus? Orare semper, iustitiam factitare, amare probitatem, humiles Secum ambulare," he wrote for his Latin handle @Pontifex-ln.
This translates as "What does the Lord command to those wholly eager for the unity of those following Christ? To always pray, to continually do justice, to love uprightness, to walk humbly with Him", according to University of Cambridge scholar Tamer Nawar.
The tweet urges his followers to pray always for the reunification of Christian churches, the BBC reports. The Orthodox church has been split from Rome for a millennium and Protestants parted ways with the Vatican in the 16th century.
But Pope Benedict's message left many Twitter users baffled, with one writing "Benny, nobody understands a word of Latin!"
The Pontiff personally approves the messages that are tweeted in his name in nine languages to his 2.5 million followers and his handle name - Pontifex - means "builder of bridges" in Latin. With just over 5000 followers, the Pope's Latin Twitter account has the smallest following of all his profiles.
