Pope Leo XIV calls for peace in Ukraine and Gaza in symbolically rich blessing on Mother's Day

VATICAN CITY (AP) — Pope Leo XIV called for a genuine and just peace in Ukraine and an immediate ceasefire in Gaza, in his first Sunday noon blessing as pontiff that featured some symbolic gestures suggesting a message of unity in a polarized Catholic Church.

“I, too, address the world's great powers by repeating the ever-present call ‘never again war,’” Leo said from the loggia of St. Peter’s Basilica to an estimated 100,000 people below.

It was the first time that Leo had returned to the loggia since he first appeared to the world on Thursday evening following his remarkable election as pope, the first from the United States. Then, too, he delivered a message of peace.

Leo was picking up the papal tradition of offering a Sunday blessing at noon, but with some twists. Whereas his predecessors delivered the greeting from the studio window of the Apostolic Palace, off to the side of the piazza, Leo went to the very center of the square and the heart of the church.

Part of that was logistics: He didn't have access to the papal apartments in the palace until later Sunday, when they were unsealed for the first time since Pope Francis' death.

Leo also offered a novelty by singing the Regina Caeli prayer, a Latin prayer said during the Easter season which recent popes would usually just recite and harked back to the old Latin Mass of the past.

Traditionalists and conservatives, many of whom felt alienated by Pope Francis' reforms and loose liturgical style, have been looking for gestures and substance from Leo in hopes he will work to heal the divisions that grew in the church. Some have expressed cautious optimism at the very least with a return to a traditional style that Leo exhibited on Thursday night, when he emerged for the first time wearing the formal red cape of the papacy that Francis had eschewed.

He followed up on Saturday by wearing the brocaded papal stole during a visit to a Marian sanctuary south of Rome. There, he knelt in reverence at the altar and greeted the crowd surrounded by priests in long cassocks usually favored by conservatives.

Aldo Maria Valli, a conservative Italian journalist who writes a popular blog, said he appreciated these gestures and urged traditionalists to give Leo a chance, saying he liked a lot of what he has seen so far. “Don't shoot Leo," he wrote.

On Sunday Leo wore the simple white cassock of the papacy and had reverted back to wearing his silver pectoral cross. He had worn a more ornate one that contains the relics of St. Augustine and his mother, St. Monica, on Thursday night that had been given to him by his Augustinian religious order.

Leo quoted Pope Francis in denouncing the number of conflicts ravaging the globe today, saying it was a “third world war in pieces.”

“I carry in my heart the sufferings of the beloved Ukrainian people," he said. “Let everything possible be done to achieve genuine, just and lasting peace as soon as possible.”

As a bishop in Chiclayo, Peru, at the start of Russia's 2022 full-scale invasion of Ukraine, then-Bishop Robert Prevost had not minced words in assigning blame to Moscow. According to a clip of a TV interview on the Peruvian show “Weekly Expression,” circulating in Italian media Sunday, Prevost said it was an “imperialist invasion in which Russia wants to conquer territory for reasons of power given Ukraine's strategic location."

In his remarks Sunday, Leo also called for an immediate ceasefire in Gaza, and for humanitarian relief to be provided to the “exhausted civilian population and all hostages be freed.”

Leo also noted that Sunday was Mother’s Day in many countries and wished all mothers, “including those in heaven” a Happy Mother’s Day.

The crowd, filled with marching bands in town for a special Jubilee weekend, erupted in cheers and music as the bells of St. Peter’s Basilica tolled.

Angela Gentile of Bari arrived in the square three hours early to be in place. Nonplussed that cardinals had elected yet another non-Italian pope, she said she was happy Leo came to the central balcony of the basilica, so the crowd could see him face-to-face. “What’s good for the Holy Spirit works for me,” she said. “I have trust.”

More than 50 pilgrims from Houston, Texas, were in the square, too, waving three large American flags. They were in Rome on a pre-planned Holy Year pilgrimage and said they were proud to be part of this historic occasion.

“Words cannot express my admiration and gratitude to God,” said the Rev. Dominic Nguyen, who led the Vietnamese American group. He said he hoped the pope would be happy to see the Stars and Stripes but also Peruvian flags and all other countries, showing the universality of the church.

Also Sunday, Leo celebrated a private Mass near the tomb of St. Peter and prayed at the tombs of several past popes in the grottoes underneath the basilica. Vatican Media filmed him praying before a mix of progressive and tradition-minded popes: Pope Paul VI, who closed out the modernizing reforms of the 1960s Second Vatican Council, and Popes Pius XII and Benedict XVI, on the more conservative end of the spectrum.

He celebrated the intimate Mass with the head of his Augustinian order and his brother, John, in the pews. In his homily, he recalled that Sunday was also the day that the Catholic Church celebrates religious vocations, and noted that the issue of declining vocations had been raised by cardinals in their pre-conclave discussions before his election.

Leo said priests can encourage more vocations by offering a good example, “living the joy of the Gospel, not discouraging others, but rather looking for ways to encourage young people to hear the voice of the Lord and to follow it and to serve in the church.”

Leo also attended the official unsealing of the papal apartments in the Apostolic Palace, which were sealed after Francis' April 21 death. It is unclear if Leo will move into the apartments or just use them for formal audiences as Francis did.

Leo has slept in his old apartment in a Vatican palazzo since his election. Francis decided to live and work at the Domus Santa Marta hotel in the Vatican rather than move into the palace, eventually taking over much of the second floor.

The 69-year-old Chicago-born missionary was elected 267th pope on Thursday. He has a busy week of audiences before his formal installation Mass next Sunday.

NEW YORK (AP) — Thousands of nurses in three hospital systems in New York City went on strike Monday after negotiations through the weekend failed to yield breakthroughs in their contract disputes.

The strike was taking place at The Mount Sinai Hospital and two of its satellite campuses, with picket lines forming. The other affected hospitals are NewYork-Presbyterian and Montefiore Medical Center in the Bronx.

About 15,000 nurses are involved in the strike, according to New York State Nurses Association.

“After months of bargaining, management refused to make meaningful progress on core issues that nurses have been fighting for: safe staffing for patients, healthcare benefits for nurses, and workplace violence protections,” the union said in a statement issued Monday. “Management at the richest hospitals in New York City are threatening to discontinue or radically cut nurses’ health benefits.”

The strike, which comes during a severe flu season, could potentially force the hospitals to transfer patients, cancel procedures or divert ambulances. It could also put a strain on city hospitals not involved in the contract dispute, as patients avoid the medical centers hit by the strike.

The hospitals involved have been hiring temporary nurses to try and fill the labor gap during the walkout, and said in a statement during negotiations that they would “do whatever is necessary to minimize disruptions.” Montefiore posted a message assuring patients that appointments would be kept.

“NYSNA’s leaders continue to double down on their $3.6 billion in reckless demands, including nearly 40% wage increases, and their troubling proposals like demanding that a nurse not be terminated if found to be compromised by drugs or alcohol while on the job," Montefiore spokesperson Joe Solmonese said Monday after the strike had started. "We remain resolute in our commitment to providing safe and seamless care, regardless of how long the strike may last.”

New York-Presbyterian accused the union of staging a strike to “create disruption,” but said in a statement that it has taken steps to ensure patients receive the care they need.

"We’re ready to keep negotiating a fair and reasonable contract that reflects our respect for our nurses and the critical role they play, and also recognizes the challenging realities of today’s healthcare environment,” the statement said.

The work stoppage is occurring at multiple hospitals simultaneously, but each medical center is negotiating with the union independently. Several other hospitals across the city and in its suburbs reached deals in recent days to avert a possible strike.

The nurses’ demands vary by hospital, but the major issues include staffing levels and workplace safety. The union says hospitals have given nurses unmanageable workloads.

Nurses also want better security measures in the workplace, citing incidents like a an incident last week, when a man with a sharp object barricaded himself in a Brooklyn hospital room and was then killed by police.

The union also wants limitations on hospitals’ use of artificial intelligence.

The nonprofit hospitals involved in the negotiations say they’ve been working to improve staffing levels, but say the union’s demands overall are too costly.

Nurses voted to authorize the strike last month.

Both New York Gov. Kathy Hochul and Mayor Zohran Mamdani had expressed concern about the possibility of the strike. As the strike deadline neared, Mamdani urged both sides to keep negotiating and reach a deal that “both honors our nurses and keeps our hospitals open.”

“Our nurses kept this city alive through its hardest moments. Their value is not negotiable,” Mamdani said.

State Attorney General Letitia James voiced similar support, saying "nurses put their lives on the line every day to keep New Yorkers healthy. They should never be forced to choose between their own safety, their patients’ well-being, and a fair contract.”

The last major nursing strike in the city was only three years ago, in 2023. That work stoppage, at Mount Sinai and Montefiore, was short, lasting three days. It resulted in a deal raising pay 19% over three years at those hospitals.

It also led to promised staffing improvements, though the union and hospitals now disagree about how much progress has been made, or whether the hospitals are retreating from staffing guarantees.
