Fathers do make a difference

In short, if a father does not go to church, no matter how faithful his wife’s devotions, only one child in 50 will become a regular worshiper. If a father does go regularly, regardless of the practice of the mother, between two-thirds and three-quarters of their children will become churchgoers (regular and irregular). If a father goes but irregularly to church, regardless of his wife’s devotion, between half and two-thirds of their offspring will attend church regularly or occasionally.
A non-practicing mother with a regular father will see a minimum of two-thirds of her children ending up at church. In contrast, a non-practicing father with a regular mother will see two-thirds of his children not attending church. If his wife is similarly irregular that figure rises to 80 percent.[33][34]
An American study found similar results on the impact of fathers:[35]
  • When both parents attend Sunday school, 72% of the children attend Sunday school when grown.
  • When only the father attends Sunday school, 55% of the children attend when grown.
  • When only the mother attends Sunday school, 15% of the children attend when grown.
  • When neither parent attends Sunday school, only 6% of the children attend when grown.
An unrelated survey in the USA also found fathers to be highly influential in church attendance. It found that if a child is the first person in a household to become a Christian, there is a 3.5% probability everyone else in the household will follow. If the mother is the first to become a Christian, there is a 17% probability everyone else in the household will follow. However, when the father is first, there is a 93% probability everyone else in the household will follow.[36][37]
