How did the Second Vatican Council fundamentally alter the identity and cultural trajectory of American Catholicism in the late twentieth century? Mark S. Massa, a Jesuit scholar, examines the seismic shifts within the American Catholic Church following the reforms of the 1960s. He argues that the council initiated a period of irreversible change that transformed the institution from a monolithic, static entity into a site of ongoing ideological conflict. By analyzing the intersection of theology and American cultural values, Massa provides a framework for understanding the persistent divisions regarding authority, gender, and morality that characterize the modern Church.

Scholars and historians frequently cite this work for its balanced approach to the internal polarization of the American Catholic Church. Readers often note that the text provides a clear, accessible entry point for understanding the complex sociological shifts that defined the post-Vatican II era.
