A self-proclaimed, non-ordained pastor/dad typically leads the family and the worship services. As opposed to regular churches that follow specific doctrines, this pastor just preaches "straight from the Bible." Because this quasi-clergyman is intimately involved in the lives of his congregation/family, the sermons can be tailored specifically to the needs of those in attendance - such as sermons about the evils of taking super long showers when someone is waiting to use the bathroom.
White Christians crave authenticity and since early Christians met in homes, home church is automatically a much more genuine worship experience. An added bonus: if white Christians can manage to work from home in addition to home schooling and home churching, they will never have any need to change out of their pajamas.
