Abstract
Using a national sample of Christians, this study compared interchurch and same-church respondents on several relationship variables and explored possible predictors of marital satisfaction. Interchurch and same-church respondents were not different on marital satisfaction or other nonreligious relationship variables but were different on several religious relationship variables. The relationship between marital satisfaction and religious heterogamy was dependent on how religious heterogamy was operationalized. Communication was the most important predictor of marital satisfaction for both interchurch and same-church respondents. Parenting variables were also predictive of marital satisfaction for both interchurch and same-church respondents.
