Bengtson says that emotional warmth rather than devoutness or discipline appears to be the key factor in families that successfully transmit religious traditions across generations. Allowing their children—particularly adolescents—to venture away from orthodox expressions of belief might seem counterintuitive to parents who want their kids to remain in the fold. Yet Bengtson’s work shows that a home environment that is nurturing but not constricting appears most likely to encourage spiritual roots to grow deep.
