This article explores the relationship between religiosity, denominational homogamy, religiosity homogamy, and marital adjustment. Using a statewide sample of spouses in first marriages (N = 1,394) and remarriages (N = 601), the authors find that within-group differences in religiosity, denominational homogamy, and religiosity homogamy are not as prevalent for spouses in remarriages. Overall, husbands and wives in first marriages who are very religious have significantly higher marital adjustment scores than spouses who are less religious. Similarly, husbands and wives in first marriages who share the same religious denomination report higher marital adjustment scores than spouses who report different denominations. For spouses in both first marriages and remarriages, those who report that they are "both religious" have higher marital adjustment scores than spouses where both partners are not religious, or where only the wife is religious. Possible reasons for the within-group similarities and differences are explored, particularly for spouses in remarriages. (Contains 3 tables.)
