Catholic world anticipates Pope Leo’s first encyclical
This date highlights the new Pope's direct connection to the tradition of social encyclicals that have defined the Church's role in the modern world, according to a report by Aleteia cited by CREDO.
The tradition of issuing social encyclicals was initiated by Pope Leo XIII, who, 135 years ago, on May 15, 1891, released the encyclical "Rerum Novarum." This document represented the Church's first systematic response to the upheavals of the Industrial Revolution, addressing issues such as workers' rights, private property, and the moral responsibilities of both employees and employers. From this document, what we now refer to as modern Catholic social teaching (or the social doctrine of the Church) emerged.
Several social encyclicals published in the decades following 1891 were timed to coincide with the anniversary of Leo XIII's encyclical.
Forty years later, on May 15, 1931, Pope Pius XI issued the encyclical "Quadragesimo Anno." Influenced in part by Jesuit thinker Oswald von Neul-Bröning, this encyclical formulated the principle of subsidiarity and clarified the Church's critique of socialism, particularly regarding its neglect of the human person and private property.
In 1961, three decades later, Pope John XXIII issued "Mater et Magistra," which advocated for greater worker participation in economic life. Additionally, on April 11, 1963, he issued another encyclical, "Pacem in Terris."
Pope Saint Paul VI continued this series with the document "Populorum Progressio," published on March 26, 1967.
Pope John Paul II revived the tradition initiated by Leo XIII with the encyclical "Laborem Exercens." Although originally scheduled for release on May 15, 1981, the document was postponed due to the assassination attempt on his life on May 13, 1981, and was ultimately published on September 14, 1981.
To commemorate the 100th anniversary of "Rerum Novarum" on May 1, 1991, Pope John Paul II issued the encyclical "Centesimus Annus," which assessed the collapse of communism and offered a measured endorsement of the market economy as a generator of prosperity, while emphasizing the need for ethical constraints.
Pope Leo XIV is now poised to continue this tradition. From the outset, he has made it clear that his pontificate is inspired by Pope Leo XIII, focusing on the significant changes facing our world, particularly through the lens of artificial intelligence, which likely explains his choice of this date.
Reports from various sources, as well as the pope's own comments, suggest that Leo XIV's encyclical, with the working title "Magnifica humanitas" ("Magnificent Humanity"), will address pressing contemporary issues. Artificial intelligence raises urgent concerns regarding human agency, labor, and responsibility. Furthermore, the fragility of international law and ongoing conflicts heighten this urgency.
What distinguishes this moment is not only the significance of the subject matter but also a deliberate appeal to history. If the encyclical is released on May 15, Leo XIV will signal that the Church's social teaching is not static; it evolves in response to new realities while remaining faithful to core principles: the dignity of every person, the priority of the common good, and the moral limits of power.
If these expectations are met, this first encyclical will place Leo XIV within a living tradition, one that continually addresses the most complex challenges of each era.
