Accidental church is the pattern of mainline Protestantism. It is marked by its chapel orientation. Church is the place where a minister performs certain spiritual tasks for the congregation, many of whom inherited the faith from their parents.
Chapel religion typically blesses the social order, comforts people in need, and trains children in the customs of the faith. Chapel-style churches are routinized organizations where members receive customs, traditions, and beliefs rather than creating new ones.
