Leo XIV will send his first Sunday blessing and speech to the crowd at St. Peter's Square in the Vatican today.

Since his election was announced on Thursday, he will recite the prayers of Regina Caeli in his first public speech in honor of the Virgin Mary.

After Sunday’s Mass is delivered, Pope Leo will bless those who gather in the square outside and deliver his thoughts.

On Saturday, he visited a shrine outside Rome and then prayed before the grave of his late ex-Francis, inside the Cathedral of Santa Maria Maggill.

Pope Leo will be officially unveiled next week on May 18 at a mass in St. Peter's Square.

The pope was elected as the new leader of the Catholic Church on Thursday after a two-day meeting in the Vatican city.

It was a busy week for the Pope, who served as the pope at Sistine Church on Friday and then spoke with the Cardinal on Saturday.

At this meeting, he described himself as an unworthy choice for the pope and vowed to continue his predecessor's "valuable legacy."

He stressed the importance of missionary work and discussions—and concern for those he called “at least and rejected.”

He explained that he chose the name Leo after the 19th century pope was famous for teaching social justice.

The new pope also proposed the development of artificial intelligence, and other advances mean that the church is necessary today to defend human dignity and justice.

Next Sunday, he will be engaging in the media before taking office on Monday.

As part of that mass, he will send a sympathy in front of many countries and guests of VIP.

The 69-year-old is the 267th occupant of St. Peter's throne and the first American to become the Pope. He will lead the Catholic Church’s 1.4 billion people worldwide.

He was born in Chicago-based Robert Francis Prevost, where he served as a missionary in Peru for many years before being appointed Archbishop. He also has Peruvian nationality.

Although Leo was born in the United States, the Vatican described him as the second pope in the Americas. Pope Francis from Argentina was the first.

Pope Leo is widely seen as moderate, and his predecessor died last month can provide “continuity” and “unity”.

The new pope is believed to have a view of Francis about immigration, the poor and the environment.

In his first speech, he told the crowd that he wanted to "seek together the United Church of Peace and Justice together."
