The name by which each pope wishes to be known says a lot about the personality and spirit he wishes to imprint on his pontificate. The new pope, Leo XIV, confirmed this Friday that he has adopted that name in honor of Leo XIII and his social encyclical, Rerum novarum, who addressed the social question in a structured way for the first time during the first great industrial revolution. "He is a figure who guides me," he assured the cardinals who elected him as their 267th pontiff. The choice of the name is no coincidence: Leo XIII (1878-1903) was the first pope of the contemporary era to develop his own social doctrine, with a conciliatory approach between capital and labor that, more than a century later, continues to inspire reformist sectors within the Church.
