In July 2012, a Holy Child sister and two Catholic Workers committed the largest breach in US nuclear security history. They entered an enriched uranium facility armed with candles, bread, Bibles, and roses, to pray and paint peace slogans. As Transform Now Plowshares, they hoped to put nuclear weapons—which target civilians in violation of the Geneva Conventions and UN treaties—on trial, making international news. This book shares their discernments of conscience and the civil resistance legacy of Plowshares with its background of Dorothy Day's Catholic Worker, while also engaging the work of the Berrigan brothers, the Catonsville nine, and the recent Kings Bay Plowshares seven. Learn their stories and see the principles of Catholic Social Teaching in action.
