On May 11, Bishop Robert J. Brennan, Bishop of the Diocese of Brooklyn, celebrated Mass at the Cathedral Basilica of St. James in Downtown Brooklyn, marking Good Shepherd Sunday with a homily reflecting on the historic election of Pope Leo XIV — the first American pope in the history of the Roman Catholic Church.
“What a great blessing we have in Pope Leo,” Bishop Brennan said. “I believe Christ has given us a pope who already loves us, who has a missionary heart and missionary feet. I believe Pope Leo will be the strong voice this world needs as he guides the Universal Catholic Church.”
This Sunday marked the fourth Sunday after Easter, known as Good Shepherd Sunday — a fitting time for Catholics to welcome a new shepherd to lead the Universal Church. It was also the first Sunday following the papal conclave that elected Cardinal Robert Francis Prevost, 69, of Chicago as Pope.
He was elected on the second day of the papal conclave at the Vatican, as announced just after 7 p.m. Rome time Thursday. Nearly an hour earlier, white smoke rose above the Sistine Chapel on the second day of the conclave, signaling that cardinals had reached a majority vote to select a successor to Pope Francis. It was one of the quickest conclave in recent memory.
The introduction was preceded with an announcement featuring the Latin phrase Habemus papam (We have a pope), followed by the new pontiff’s identity and the name he has taken for his papacy. Then came the stunning announcement of Prevost’s election, the first American ever to occupy the holy see, and that the new pontiff took the name Leo XIV.
Moments later, the newly minted Pope Leo XIV approached the main balcony of St. Peter’s Square to address the thousands of jubilant people who gathered for the announcement. He wore the regal red vestments that Pope Francis notably declined to wear upon his election in 2013.
In his first remarks, Pope Leo paid tribute to the late Pope Francis, thanked the cardinals for electing him and stressed the importance of being charitable as a united church, while offering a solemn blessing to the entire world.
Leo also said he envisioned the Catholic Church as an entity that “builds bridges with dialogue.”
“Thank you to my Cardinal brothers who chose me to be the Successor of Peter and to walk together with you as a united Church searching all together for peace and justice, working together as women and men, faithful to Jesus Christ without fear, proclaiming Christ, to be missionaries, faithful to the gospel,” he said.
“We have to look together how to be a missionary Church, building bridges, dialogue, always open to receiving with open arms for everyone, like this square, open to all, to all who need our charity, our presence, dialogue, love,” Pope Leo continued.

Prevost served as the Archbishop of Chiclayo, Peru, before being appointed by Pope Francis in 2023 to lead the Vatican’s Dicastery for Bishops, the office responsible for overseeing the appointment of bishops worldwide. Pope Francis made Prevost Cardinal in the Consistory in 2024 and assigned him the Diaconate of Saint Monica.
