The Catholic Worker movement began in 1933, founded by Dorothy Day and Peter Maurin in the United States. It combines faith and social justice, advocating for the poor and marginalized through direct action and community living. The movement emphasizes the importance of hospitality, nonviolence, and the dignity of every person. The Catholic Worker operates numerous houses of hospitality, providing food, shelter, and support to those in need. It also publishes a newspaper, the Catholic Worker, which discusses social issues from a Catholic perspective. The movement encourages individuals to engage in acts of service and promote social change through grassroots efforts.
