The Catholic Worker Movement is a social and religious movement founded in 1933 by Dorothy Day and Peter Maurin. It emphasizes the importance of hospitality, community, and social justice, aiming to address the needs of the poor and marginalized. The movement promotes a lifestyle of voluntary poverty and nonviolence, rooted in Catholic teachings. The movement is known for establishing Catholic Worker Houses, which provide shelter and support for those in need. It also publishes a newspaper called the Catholic Worker, which discusses social issues and advocates for peace and justice. The movement continues to inspire activists and communities worldwide.
