VATICAN CITY — Pope Francis emerged from his convalescence on Easter to bless thousands of people in St. Peter’s Square and treat them to a surprise popemobile romp through the piazza, drawing wild cheers and applause as he continues his recovery from a near-fatal bout of double pneumonia.

“Viva il Papa!” (Long live the pope), “Bravo!” the crowd shouted as Francis looped through the square in his open-topped popemobile and then up and down the main avenue leading to it.

He stopped occasionally to bless babies brought up to him, a scene that was common in the past but unthinkable just a few weeks ago as the 88-year-old pope fought for his life.

“Brothers and sisters, Happy Easter!” Francis said, his voice sounding stronger than it has since he was released from the hospital March 23 after a five-week stay.

Francis didn’t celebrate the Easter Mass in the piazza, delegating it to Cardinal Angelo Comastri, the retired archpriest of St. Peter’s Basilica. But after the Mass ended, Francis appeared on the loggia balcony over the basilica entrance for more than 20 minutes and imparted the apostolic blessing in Latin.

The crowd of people below, estimated by the Vatican to be more than 35,000, erupted in cheers as a military band kicked off rounds of the Holy See anthem.

In all, Francis was outside on a sunny spring day for around 50 minutes, with temperatures at 70 Fahrenheit in a piazza awash in daffodils, tulips and other flowers donated by the Netherlands for Easter.

“It is excellent, a miracle,” said Margarita Torres Hernandez, a pilgrim from Mexico who was in the square. “Now that he has come out, for me it’s a miracle, it’s something very big, very beautiful.”

Francis has appeared in public only a handful of times since returning to the Vatican after a 38-day hospital stay. He skipped the solemn services of Good Friday and Holy Saturday leading up to Easter, but he had been expected to make an appearance Sunday.

Doctors have prescribed two months of convalescence and respiratory therapy to improve his lung function after he came down with a life-threatening case of double pneumonia. He still seems to require great effort to project his voice, and his breathing remains labored. But his voice sounded stronger than it has to date in the few words he uttered from the loggia.

“It was a very touching moment for us (to see the pope),” said Marcin Popowsky, a pilgrim from Poland. “And we are very happy that we can see a pope in good shape.”

Easter is the most joyful moment on the Christian liturgical calendar, when the faithful celebrate the resurrection of Christ after his crucifixion. This year, Easter is being celebrated on the same day by Catholics and Orthodox Christians, and has been marked by Russia’s announced temporary Easter truce in its war in Ukraine.

Easter at the Vatican traditionally involves a Mass and the pope’s Urbi et Orbi blessing (Latin for “to the city and the world”), a papal speech delivered from the loggia which is usually a roundup of global hot spots and human suffering.

In the speech, read by Archbishop Diego Ravelli, master of liturgical ceremonies, Francis appealed for peace in Gaza and Ukraine, as well as Congo and Myanmar and in other hotspots. And he made a special appeal for migrants and those affected by violence.

“How much contempt is stirred up at times toward the vulnerable, the marginalized, and migrants!” the message said. “On this day, I would like all of us to hope anew and to revive our trust in others, including those who are different than ourselves, or who come from distant lands, bringing unfamiliar customs, ways of life and ideas! For all of us are children of God!”
