It’s been 10 days since the new Bishop of Rome, Pope Leo XIV, was announced after the passing of Pope Francis on Easter Monday (April 21).

The 69-year-old has already held his first mass, where he spoke in English, and made his social media debut ahead of his inaugural mass scheduled for this Sunday (May 18) at the Vatican.

Recently, people got a first look at Pope Leo’s official papal portrait, which sparked some curiosity.

The image shows the Chicago-born pope in his white robes, wearing a large gold cross, smiling gently at the camera.

In the bottom right corner of the portrait is his Coat of Arms and a Latin phrase: “In illo uno unum,” which means “In the One, we are one.”

Next to it is a handwritten signature, likely by Pope Leo himself, saying: “Leo P.P.XIV.”

One Reddit user asked what the “P.P.” stood for, writing: “What does the ‘P.P.’ in the middle mean?”

Another commented: “I’ve wondered that for years. I think ‘P.M.’ used to be used, which stands for ‘Pontifex Maximus.'”
