"The Catholic Worker Movement, founded by Dorothy Day and Peter Maurin in 1933, is grounded in a firm belief in the God-given dignity of every human person.
Today over 185 Catholic Worker communities remain committed to nonviolence, voluntary poverty, prayer, and hospitality for the homeless, exiled, hungry, and foresaken. Catholic Workers continue to protest injustice, war, racism, and violence of all forms."
http://www.catholicworker.org/While the movement is Catholic, in the best sense of our tradition, you can be certain that neither the present nor recent past pope would have had much use for them. Their challenge to capitalism, commitment to the poor, dedication to peace and the forsaken are not the kinds of things that are institution friendly.
Some of their communities are on those government lists of dangerous organizations.
