Dorothy Day, whom I knew personally, was actually an extremely devout Catholic. She was a pacifist and had a sort of utopian-agrarian-community ideal, not unlike Chesterton and many other Catholic intellectuals of her time and a little before. Before becoming a Catholic, she had been a Communist, and the Worker unfortunately became a magnet for all sorts of flakes during the Vietnam War (think Berrigan Brothers). But she herself was not a flake, was enormously, traditionally pious and had a great devotion to the Blessed Sacrament.
