What does Pope Leo XIV's name choice signify?
Cardinal Robert Francis Prevost, who became the first-ever American Pope, has taken the name Pope Leo XIV. Holy See Press Office Director Matteo Bruni said that the pontiff's choice was a "clear and deliberate" reference to Pope Leo XIII. Pope Leo XIII authored the 1891 encyclical 'Rerum Novarum', which marked the beginning of the Church's modern social doctrine, he added.
