Pacem in Terris
In 1963 while the United States and its allies were locked in a Cold War showdown with the Soviet Union and its satellite nations, Pope John XXIII, a peacemaker of extraordinary influence, issued the encyclical Pacem in Terris, “Peace on Earth.” In this seminal document for world peace, Pope John XXIII called on all peoples to respect the human dignity of all persons and to begin an authentic dialogue in the quest for peace and human fulfillment.
Pacem in Terris Lecture Series
Inspired by the vision of Pope John XXIII, the Georgetown University established the Pacem in Terris Lecture Series. This series examined issues and prospects in the global imperative for peace with a series of presentations by distinguished scholars, religious leaders, and human rights activists from around the world.
The Pacem in Terris lecture series was a collaboration sponsored by the Office of the President, the Catholic Studies Program, the Center for Social Justice Research, Teaching and Service, the Office of Mission and Ministry, and the Woodstock Theological Center.
Speeches from the Pacem in Terris Lecture Series
The series, active from 2003 through 2006, featured global leaders and scholars addressing the Pacem in Terris document’s four pillars: Truth, Justice, Love, and Freedom.
Pacem in Terris 50th Anniversary Conference
To commemorate the 50th anniversary of Pacem in Terris, Georgetown University hosted a conference on April 12, 2013, “Human Dignity in World Affairs: Celebrating Pacem in Terris and its Legacy.”

Pope John XXIII promulgated Pacem in Terris, “Peace on Earth”, on April 11,1963, in the depths of the Cold War and after the Second Vatican Council had concluded its first of four sessions.
Released just weeks before his death but five months after the chilling standoff between President Kennedy and Premier Khrushchev in the Cuban Missile Crisis, the encyclical became the decisive last will and testament of Pope John and the charter Vatican II needed to embrace an agenda for peace, human dignity and human rights. Fifty years later, the ideas developed in Pacem in Terris retain their centrality for contemporary world affairs.
