Pax Christi USA is a partner in the Catholic Nonviolence Initiative (CNI), a project of Pax Christi International, which affirms the vision and practice of active nonviolence at the heart of the Catholic Church, and is committed to the long-term vocation of healing and reconciling both people and the planet. 

CNI was launched soon after the Nonviolence and Just Peace conference — co-sponsored by the Pontifical Council for Justice and Peace (now part of the Dicastery for Promoting Integral Human Development), Pax Christi International, and other international bodies — in Rome in April 2016. Lay people, theologians, members of religious congregations, priests and bishops from Africa, the Americas, Asia, Europe, the Middle East and Oceania gathered to call on the Catholic Church to take a clear stand for active nonviolence and against all forms of violence. In his message to the conference, Pope Francis said, “Your thoughts on revitalizing the tools of nonviolence, and of active nonviolence in particular, will be a needed and positive contribution.”

Two subsequent conferences were held in Rome, one in April 2019 and one in December 2022.
