In the five decades of Pax Christi USA’s history, at key moments we have identified and honored extraordinary and experienced leaders within the Pax Christi USA community and commissioned them to represent our movement through ongoing outreach efforts. These “Ambassadors of Peace” are chosen for the contributions they have made in preaching and practicing gospel nonviolence, peacemaking, reconciliation and justice.

Ambassadors of Peace promote the mission of Pax Christi USA through word and witness, sharing our programs and campaigns with new audiences, serving as our representatives in coalitions, and generally carrying the message of Pax Christi USA wherever they go. They serve as living embodiments to our community and beyond of what it means to live a life rooted in the “peace of Christ”.
