The Amish, Mennonites, Bruderhoff, Hutterites, and other Anabaptist brethren hold to the doctrines of “non-resistance” and “non-participation”.
Non-resistance:
Jesus said, “Resist not evil.”
Non-participation:
Jesus said, “My Kingdom is not of this world.”
Jesus also said to be in the world not of it. He also said the go and make disciples of all nations. I can’t see how hou can do that by locking your selves up in inward facing communities.
