Parents play an important role in shaping the faith of their children. Prior research demonstrates that the quality of parent-child relationships and the incorporation of spiritual disciplines into the home matter to faith formation. However, the association between spiritual disciplines and the quality of parent-child relationships has not previously been explored. We consider a particular spiritual discipline--family devotions--which we define as the regular and intentional spiritual discipline practiced in the home that incorporates Bible reading, prayer, and other devotional materials. We survey a sample of 2397 parents of children enrolled in private Christian schools on family devotions practices and parent-child relationships. We find that parents who report consistently engaging in family devotions are more likely to report willingness to talk with their child about faith, spending quality time as a family, and openness to other conversations with their child.
