Peace churches are Christian churches, groups or communities advocating Christian pacifism or Biblical nonresistance. The term historic peace churches refers specifically only to three church groups among pacifist churches:
- Church of the Brethren, including all daughter churches such as the Old German Baptist Brethren, Old Brethren and Dunkard Brethren;
- Religious Society of Friends (Quakers); and
- Anabaptists, including Mennonites, Amish and Hutterites.
In addition to the Schwarzenau Brethren and Mennonites, other Anabaptist Christian fellowships, such as the Hutterian Brethren, River Brethren, Apostolic Christian Church and Bruderhof teach pacifism as well.
