Among all Christian denominations, there have always been groups of members who advocate nonviolence, but certain churches have consistently supported it since their foundation. Besides the three historic peace churches, they include the Amish, Old Order Mennonites, Conservative Mennonites, Hutterites, Old German Baptist Brethren, Old Order River Brethren, the Brethren in Christ, and others in the Anabaptist tradition; Doukhobors, Molokans, Dunkard Brethren, "Dukh-i-zhizniki", Bruderhof Communities, Schwenkfelders, Moravians, the Shakers, and even some groups within the Pentecostal movement. The largest Pentecostal church, the Assemblies of God, abandoned pacifism around the time of the Second World War. These groups have disagreed, both internally and with each other, about the propriety of non-combatant military roles, such as unarmed medical personnel, or performing non-battlefield services that assist nations in wartime, such as manufacturing munitions. One position might argue that Jesus would never object to helping people who are suffering, while another might object that doing so contributes indirectly to violence by freeing other people to engage in it. Most peace churches support Alternative service options such as service to refugees or in hospitals, as long as they are not associated with the military.
