Being Excommunicated
Although Meidung refers to being shunned by the Amish, Bann is a far more serious punishment. You’ll be placed in the Bann and treated as an outsider if the transgression is severe enough to result in permanent excommunication. You may be shunned for an extended period of time depending on your ‘crime.’ Even if it appears harsh, the goal is for the person to admit their mistake and apologize.
DNA Testing
Thanks to modern technology, everyone nowadays wants to get DNA testing to learn more about their ancestors and possibly locate long-lost relatives except for the Amish, who will not allow it. That is why it is so simple to marry your third cousin in their community. They believe that inbreeding is a result of God’s will.
