In an attempt to locate the origins of the American Catholic peace movement I was able to identify two possible antecedents: the Catholic Association for International Peace (CAIP) and the Catholic Worker movement. Though the latter proved to be the leaven within American Catholicism that fostered the phenomena to emerge in force during the Vietnam era and continue to the present day, both groups had to be presented in order to provide a full understanding of the various approaches to peace- making.
