Pope Leo XIV has arrived at his inauguration at St Peter’s Square, greeting Catholic faithful and blessing babies from his Popemobile as he drove through the crowd.

Ahead of the ceremony, where he will formally take up his role as leader of the global Catholic Church, the Pope — US-born Robert Prevost — was driven through tens of thousands of well-wishers, including dozens of world leaders and European royalty.

Catholics are expected to cram the square and surrounding streets in Rome for the formal celebration, which starts at 10am local time on Sunday (6pm AEST) and includes the first ride in the white Popemobile by Leo, the first Pope from the United States.

Born in Chicago, the 69-year-old pontiff spent many years as a missionary in Peru and also has Peruvian citizenship, meaning he is also the first Pope from that South American nation.

Prevost, a relative unknown on the world stage who only became a cardinal two years ago, was elected Pope on May 8 after a short conclave of cardinals that lasted barely 24 hours.

He replaces Pope Francis from Argentina, who died on April 21 after leading the church for 12 often turbulent years during which he battled with traditionalists and championed the poor and marginalised.

US Vice President JD Vance, a Catholic convert who clashed with Francis over the Trump administration’s hard-line immigration policies, will lead a US delegation alongside Secretary of State Marco Rubio, who is also Catholic.

Ukrainian President Volodymyr Zelenskiy will also attend and would be happy to meet other leaders, a top aide has said, as he did at Francis’ funeral when he had face-to-face talks with US President Donald Trump in St Peter’s Basilica.

Zelenskiy last met Vance in February in the White House, when the two men clashed fiercely in front of the world’s media.

Also expected at the Vatican ceremony are the presidents of Peru, Israel and Nigeria, the prime ministers of Italy, Canada and Australia, German Chancellor Friedrich Merz and European Commission President Ursula von der Leyen.

Many European royals will also be in the VIP seats near the main altar, including Spanish King Felipe and Queen Letizia.

In various sermons and comments since his election as Pope, Leo has praised Francis repeatedly but has not offered many hints about whether he will continue with the late pontiff’s vision of opening the church up to the modern world.

His homily on Sunday is likely to indicate some of the priorities for his papacy, having already made clear over the past 10 days that he will push for peace whenever possible

His first words in an appearance to crowds in St Peter’s Square on the night of his election were “Peace be with you all”, echoing words Catholics use in their celebrations.

Sunday’s Mass will feature prayers in several languages, in a nod to the global reach of the 1.4-billion member church, including Latin, Italian, Greek, Portuguese, French, Arabic, Polish, and Chinese.

As part of the ceremony, Leo will also formally receive two items as he takes up the papacy: a liturgical vestment known as a pallium, a strip of lambswool which represents his role as a shepherd, and a special band known as the fisherman’s ring.

The ceremonial gold signet ring is specially cast for each new Pope and can be used by Leo to seal documents. It features a design of St Peter holding the keys to heaven and will be broken after his death, marking an end to his papacy.
