When prophets are honored, it is time to be wary. Placing prophets on pedestals can be a way not only of disarming them but also of evading all the lessons they can teach. American Catholic radicals, for instance, occupy several revered niches in the history of American Catholicism. Here, Dorothy Day and Peter Maurin break bread on Mott Street and milk cows on Maryfarm; there, Daniel Berrigan destroys draft records and leads G-men on a merry chase through New England. Though vilified in their times, this communion of saints now commands respect in most quarters of American Catholic intellectual life and could even constitute a Catholic wing in the pantheon of American radicalism.
