Rome became the epicenter of a global faith movement over the weekend, as more than 1 million young Catholics answered Pope Leo XIV’s call for faith and service.

"My young brothers and sisters, you are the sign that a different world is possible," the pontiff told the Jubilee of Youth crowd in Tor Vergata, encouraging the sea of young faithful to embrace dialogue over division.

Father Michael Tidd, headmaster at the Delbarton School in Morristown, New Jersey, told Fox News Monday that Pope Leo’s message deeply resonated with the audience.

"I think what Pope Leo says that resonates so well is that he's not afraid to ask hard questions and to challenge young people to live their faith more deeply, more authentically, to go beyond themselves and not just worry about their own concerns, but seek the good of their brothers and sisters," he told "Fox & Friends."

According to Tidd, the pope's ability to connect stems from a natural "ease," a way of communicating that is neither overbearing nor condescending.

Rather than lecturing the young Christians, he speaks to them personally, with a touch of warmth and wisdom.

"He has an ability to engage readily, and you see that in his smaller audiences and the audiences at St. Peter's Square and certainly even here, his ability to catch their attention and to have them listen to him, not as someone who's admonishing them or chastising them, but someone who is encouraging, almost like a coach," Tidd observed.

"[He's] encouraging them, motivating them to seek a deeper relationship with Christ, and also to bring the fruits of that relationship to their relationships with their brothers and sisters."

The pope presided over a prayer vigil Saturday evening on the outskirts of Rome where he answered questions from young pilgrims, followed by a Sunday mass.

A third child has died, nearly a week after suffering critical injuries when a barge struck and sank a sailboat that was part of a sailing camp in Miami, the U.S. Coast Guard said Sunday.

The Coast Guard confirmed the death of a 10-year-old girl, though they did not provide her identity.

"Our hearts continue to mourn with all those impacted by Monday’s tragic incident, especially with the passing of another one of Miami’s children today," said Capt. Frank Florio, commanding officer of Coast Guard Sector Miami. 

The former mayor of Bal Harbour, Florida, Gabriel Groisman, later identified the 10-year-old as his cousin, Arielle Buchman, in a post on X.

"On the saddest day of the Jewish calendar, my family mourns the loss of our 10-year-old cousin Arielle, who passed away as a result of a tragic sailboat accident that occurred early in the week," he posted Sunday, referencing Tisha B'Av, a Jewish day of mourning commemorating the anniversaries of the destruction of the first and second Temple's in Jerusalem.

All six people on the sailboat were pulled from the water after the barge struck the sailboat at 11:30 a.m. on July 28 in Biscayne Bay, and four children were rushed to a hospital.

A 7-year-old girl, identified as Mila Yankelevich, and 13-year-old Erin Ko Han were pronounced dead shortly after arriving at the hospital. Mila was the granddaughter of an award-winning Argentinian TV producer, Cris Morena, according to La Nacion. The Argentine Consulate in Miami confirmed her identity with Fox News Digital. 

An 8-year-old girl was in critical condition as of Tuesday. A 19-year-old woman and a 12-year-old girl were rescued but not hospitalized.

Officials did not immediately reveal a cause of the crash. Salvage operations began Tuesday.

"The Coast Guard remains committed to conducting a thorough investigation to ensure all facts are uncovered," Florio said.

Florio said in a Tuesday evening press conference that the young girls were wearing life vests at the time of the collision.

Florio said the tugboat captain's alcohol level was tested after the crash, which is standard procedure. He did not disclose the test results or details of the captain’s statement to investigators.

The popular sailing program, started in 1927, boasts of summer camps in a "very secure area at the Biscayne Bay," their website says. Biscayne Bay is a heavily trafficked waterway, serving commercial shipping, recreational boating, sailing camps and clubs, and fishing and diving.
