Excommunication
Excommunication, on the other hand, is much more serious. The excommunication process involves the complete shutdown of contact with a person. It usually leads to banishment from the community. Even parents of an excommunicated child are no longer allowed to have contact with them.
No Cars, Ever
Members of the Amish community are not allowed to operate cars. The Amish horse and buggy is a very common thing to see if you're passing through Amish country! They believe that working together as a community is very important and that using a car would hinder that sense of community and the idea that they need to rely on one another.
