Perhaps no one had a greater influence on the Roman Catholic Church in the twentieth century than Pope John XXIII. Born Angelo Roncalli (1881–1963), he rose from humble beginnings to become a passionate advocate for social justice and world peace. Canonized by Pope Francis in 2014, he was known for his compassion and charity.

In this course, you will join the late ecclesial expert and Georgetown professor Gerard Mannion to experience the enduring charisma of Saint John XXIII. In 12 fascinating lectures, you will journey through his inspiring life, his powerful leadership in calling the Second Vatican Council, and his lasting legacy for the world today.

John XXIII (r. 1958–1963) enchanted the world with his charismatic papacy that stressed peace and justice. A true shepherd for the people, he united cultures across the globe and championed interreligious dialogue. Facing a world torn apart by war and conflict, he united people around the globe with his message of love and warm teaching style.

All of this would have marked him as a great pope, but his greatest achievement was the calling of the Second Vatican Council (1962–65), which he called to bring the church “up to date” (aggiornamento). In introducing this reform, John XXIII changed the Church forever.
