In the wake of the Civil War, Father Isaac Hecker launched several publishing ventures to advance his dream of a Catholic America, but he and his partners soon found themselves embroiled in a debate with other American Catholics, notably his friend and fellow convert Orestes Brownson, over the “use and abuse of reading.” Although the debate was certainly part of a contemporary conversation about the compatibility of Catholicism and American culture, this essay argues that it was equally rooted in a moment of American anxiety over a shifting social order, a moment when antebellum faith in the individual was being tested by the rights claims of women and Americans of color. Tacitly accepting and internalizing historical claims of intrinsic and through-going Catholic “difference,” claims offered both by American Protestants and American Catholics like Brownson, scholars often presume that debates within American Catholicism reflect “Catholic” concerns first and foremost, qualifying their utility as sources of “American” cultural history. By examining American Catholic discussions of reading, individual liberty, social order, and gender in the 1860s and 1870s, this essay argues that Brownson's arguments against the compatibility of American and Catholic life were in fact far more representative of ascendant ideas in American culture than Hecker's hopeful visions of a Catholic American future made manifest through the power of reading. In doing so, it demonstrates the ways that American Catholicism can be a valuable and complex site for studying the broader history of religion and culture in the United States.
