Abstract

Nonviolent action is activity undertaken to call for, struggle for, or achieve change without using violence. This paper examines St. John XXIII’s historic encyclical on world peace, Pacem in terris, and its relationship to nonviolent action. It focuses on two nonviolent actions that contributed to this historic magisterial teaching: John’s efforts to foster a resolution to the Cuban Missile Crisis and a fast undertaken by the spiritual activist Lanza del Vasto during Lent 1963. It argues that the very writing of this papal letter was a form of nonviolent action and that it has inspired nonviolent action around the world since it was promulgated, including Catholic leadership in the People Power Revolution in the Philippines.
