Being Excommunicated
Although Meidung relates to being shunned by the Amish community, Bann is a much more severe penalty. If the transgression is severe enough to result in permanent excommunication, you’ll be put in the Bann and treated as an outsider. Depending on your ‘crime,’ you may be shunned for an extended period of time. Even if it can seem harsh, the goal is for the individual to recognize their error and apologize.
DNA Testing
Everyone nowadays wants to get DNA testing to learn more about their ancestors and maybe locate long-lost relatives, thanks to modern technology. All except the Amish, who refuse to allow it. That is why marrying your third cousin in their community is so easy. They assume it is God’s will that inbreeding exists.
