The mennonites follow Menno Simmons and the Amish follow some guy with “Am” in his name (not enough time for a lookup, here).
My grandparents are Mennonites, and my grandmother was raised Amish. When her family left the order, they became Mennonites. My grandfather became a Mennonite when a Mennonite Church was built in his Cleveland-suburb neighborhood in 1950.
Anyway, I don’t think the two religions are related other than they originated in the same areas (Germany then Switzerland) and many Mennonite women do practice plain dress and covering their heads (only at church, I think.) My grandparents are as modern as anyone.
Here’s some major differences between my grandparents’ church and their Amish neighbors, off the top of my head:
-Mennonites worship in a church with a pastor. Amish worship at parisoners’ homes every other week with a guy who was appointed to lead the service.
-Mennonites drive cars, have electricity and enjoy a completely “modern” life. Amish do not, to varying degrees.
-Amish only marry Amish or they become “English.” Mennonites can marry whoever and stay Mennonites.
-Amish belong to districts, which are basically geographical due to their lack of far-reaching transportation. Mennonites live wherever they want and go to whatever church they please.
-Mennonite pastors are ordained (and go to school). Amish “pastors” are guys who are picked nearly at random by some ceremony involving the Bible and pieces of paper.
-Amish services are in German (or old German) which is not the language Amish people speak. They speak Pennsylvania Dutch and don’t understand German. They also don’t learn English until they’re about 5 or 6. Mennonites are raised to speak English (in America) and their services are in English (of course this can vary).
-Amish kids can go to an Amish school which is in their community and usually a 1-room schoolhouse. Class is usually taught by a young girl who has nothing more than an 8th grade education. They have the option of going to an English school, and many do. Many don’t go past 8th grade (and don’t have to). Mennonite kids go to school with your kids.
-Amish men sport beards once they’re married. They also are likely to build on to their houses once their kids get married and have the new family live right there. Mennonites don’t do the beard thing and I am not aware of any building on for new additions to the family.
Some similarities:
-Both are religions that began in Germany and have many German-based traditions.
-Almost all Amish are farmers, whether they are commercial or substinance farmers. Mennonites can be farmers too.
-Both have intense “love thy neighbor” ideals and are welcoming and humble people.
-Some Mennonite women practice head covering and plain dress and all Amish women do.
