Ordnung is a term used by Amish and Old Order Mennonites for a rule set for church members which sets out a way to live. These rules vary by district and are usually unwritten. Examples might be personal behavior, clothing, transportation, and marriage behavior.
Based on the true crime book: A Killing in Amish Country: Sex, Betrayal, and A Cold-Blooded Murder by Gregg Olsen and Rebecca Morris.
Amish men only wear beards after marriage; since they don't wear wedding rings, the beard is how one knows a man's marital status. Amish men also leet their beards grow naturally without cutting or trimming them, based on Leviticus 19:27. The characters in this movie have beards that are too short and too neatly trimmed. Mustaches are a no-no as well. Eli Weaver was among old order amish, and it seems that the movie does not reflect how conservative they are. Some old order amish don't even allow indoor plumbing. There are also some groups of Amish that don't practice rumspringa.
