This book investigates the shifting landscape of marriage within Christian communities and the sociological factors contributing to its declining stability. Mark Regnerus, a professor of sociology, utilizes a combination of quantitative survey data and qualitative in-person interviews to analyze how modern cultural shifts, economic uncertainty, and changing gender dynamics impact the institution of marriage. The author argues that the transition from marriage as a foundational life event to a 'capstone' achievement has created significant barriers for younger generations of believers.

Sociologists and religious scholars frequently note the empirical rigor Regnerus applies to a topic often discussed through purely theological lenses. Experts highlight this as a significant contribution to understanding the intersection of modern secular culture and traditional religious practice.
