This book investigates how the structure of the American Catholic parish influences the integration and exclusion of diverse cultural and linguistic groups within the church. Tricia Colleen Bruce, a sociologist of religion, utilizes a combination of national survey data and qualitative case studies to examine the tension between traditional parish boundaries and the reality of a pluralistic Catholic population. She argues that the institutional framework of the parish often dictates the success or failure of efforts to accommodate difference, ultimately shaping the communal identity of the faithful.

Scholars in the sociology of religion identify this work as a significant contribution to the study of institutional adaptation in modern religious organizations. Readers frequently note the academic rigor of the text, which serves as a foundational resource for understanding the intersection of geography, culture, and ecclesiastical policy.
