Pope Leo XIV has signed his first encyclical Magnifica Humanitas, or “Magnificent Humanity” on May 15, 2026. The encyclical will be presented May 25 and is expected to outline the Pope’s moral vision for engaging with artificial intelligence.

In the early days of his pontificate, Leo signaled his intention to follow the path of both his predecessor and his namesake, Pope Leo XIII (1810-1903). Leo XIII’s landmark encyclical Rerum Novarum (“Of New Things”) is widely regarded as the first major social encyclical of the modern papal era.

June 18th, the ICP organizes an evening of close reading of Magnifica Humanitas, exploration of Catholic Social Teaching against the background of the encyclical Rerum Novarum.
