In the 1930s, Day worked closely with fellow activist Peter Maurin to establish the Catholic Worker Movement, a pacifist movement that combines direct aid for the poor and homeless with nonviolent direct action on their behalf. She practiced civil disobedience, which led to additional arrests in 1955,[5] 1957,[6] and in 1973 at the age of seventy-five.[2] As part of the Catholic Worker Movement, Day co-founded the Catholic Worker newspaper in 1933, and served as its editor from 1933 until her death in 1980. In this newspaper, Day advocated the Catholic economic theory of distributism, which she considered a third way between capitalism and socialism.[7][8] Pope Benedict XVI used her conversion story as an example of how to "journey towards faith... in a secularized environment."[4] Pope Francis included her in a short list of exemplary Americans, together with Abraham Lincoln, Martin Luther King, Jr., and Thomas Merton, in his address before the United States Congress.[9] The Church has opened the cause for Day's possible canonization, which was accepted by the Holy See for investigation.
