Commager, Henry Steele. Theodore Parker: Yankee Crusader.

Boston: Little, Brown and Company, 1936. In it, Commager writes, “But Boston would not stay revived; a backsliding city, Boston, what with so much of wealth and worldliness, what with pale Unitarians indifferent to salvation, and smug Episcopalians sure of salvation, and proud Congregationalists who were bent on being saved their own way, what with Theodore Parker there in his Music Hall every Sunday, thousands of people crowding to hear his blasphemies.”
