Pope John XXIII

This individual is not a direct affiliate of the Berkley Center.

During his short reign (1958-1963), Pope John XXIII (Angelo Giuseppe Roncalli) ushered in a new era for the Roman Catholic Church. John stunned the world when he convened the Second Vatican Council for the explicit purpose of bringing the Church forward into the modern era (aggiornamento), and it proved to be the most important ecclesial moment in centuries. In a break with tradition, John invited Protestant and Orthodox leaders and later hosted the world's foremost political leaders. His impassioned plea to US and Soviet leaders at the height of the Cuban Missile Crisis was deemed instrumental in cooling hostilities. John issued two major encyclicals, Mater et Magistra and Pacem in Terris, in which he exhorted the people of the world to work towards the common good. John XXIII was declared "Blessed" in a 2000 beautification ceremony conducted by Pope John Paul II and canonized by Pope Francis in 2014.
