Pope Leo XIV celebrates first Mass as pope and calls his election both a cross and a blessing

VATICAN CITY – Pope Leo XIV, history’s first U.S.-born pontiff, said Friday that his election was both a cross to bear and a blessing as he celebrated his first Mass as the head of the Catholic Church.

Leo spoke off-the-cuff in English in the Sistine Chapel to the cardinals who elected him to follow in the footsteps of Pope Francis, who put a commitment to social justice at the core of his papacy. He acknowledged the great responsibility they had placed on him before delivering a brief but dense homily on the need to joyfully spread Christianity in a world that often mocks it.

“You have called me to carry that cross and to be blessed with that mission, and I know I can rely on each and every one of you to walk with me as we continue as a church, as a community, as friends of Jesus, as believers, to announce the good news, to announce the Gospel,” he said.

The Mass was in the same frescoed chapel that Leo, the Chicago-born Augustinian missionary Robert Prevost, was elected Thursday afternoon as the 267th pope, overcoming the traditional taboo against a pontiff from the United States because of the secular power the country wields.

On Sunday, he is set to deliver his first noon blessing from the loggia and attend an audience with the media on Monday in the Vatican auditorium.

Leo will be formally installed as pope at a Mass on May 18, the Vatican said Friday, and will preside over his first general audience May 21. Meanwhile, he asked all Vatican leaders, who technically lost their jobs when Francis died April 21, to remain in their posts until he decides definitively on whether to confirm them.
