This study examines religious differences in attitudes toward divorce laws among U.S. adults. Using pooled data from the 2000-2006 NORC General Social Surveys (N = 5,683), we find that frequency of religious attendance and belief that the Bible is the Word of God are strong predictors of support for stricter laws governing divorce. Indeed, these religious indicators are much more important than conservative affiliation. Conversely, more secular individuals, that is, those who do not attend religious services and consider the Bible only a book of fables and moral teachings, are substantially less supportive of tightening existing divorce laws. Understanding the role of religion in shaping Americans' attitudes toward divorce laws can illuminate the scope and boundaries of connections between the institutions of marriage and religion in the contemporary United States as well as inform policy implications for the future of divorce law reform.
