The Mennonites are the largest and most significant group of non-resistants. For over four hundred years they have maintained their religious views, and applied them with remarkable consistency.[92] Their church grew out of the Anabaptist movement, which had its origins in Switzerland shortly after 1520. The Anabaptists believed in the literal acceptance of the teachings of the Bible, and their application as rules of conduct in daily life. Since they did not depend for their interpretations upon the authority of any priesthood or ministry, differences grew up among them at an early date. The more radical wing, from which the Mennonites came, accepting the Sermon on the Mount as the heart of the Gospel, early refused to offer any physical resistance to evil.[93] Felix Manz, who was executed for his beliefs in 1527, declared, "No Christian smites with the sword nor resists evil."[94] Hundreds of other Anabaptists followed Manz into martyrdom without surrendering their faith.

In a day before conscription had come into general use, the Anabaptists suffered more for their heresy and their political views than they did for their non-resistance principles. In their belief in rendering unto Caesar only those things which were Caesar's and unto God the things that were God's, they came into conflict with the authorities of both church and state. The established church they refused to recognize at all, and they came to regard the state only as a necessary instrument to control those who had not become Christians. Far in advance of the times they adopted the principle of complete separation of church and state, which for them meant that no Christian might hold political office nor act as the agent of a coercive state, although he must obey its commands in matters which did not interfere with his duty toward God. On the basis of direct scriptural authority, they placed the payment of taxes in the latter category.[95]

The modern Mennonites are descended from the followers of Menno Simons, who was born in the Netherlands in 1496. In 1524 he was ordained as a Catholic priest, but he soon came to doubt the soundness of that religion, and found his way into Anabaptist ranks, where he became one of the leading expounders of the radical principles, placing great emphasis upon non-resistance. In his biblical language, he thus stated his belief on this point:

"The regenerated do not go to war, nor engage in strife. They are the children of peace who have beaten their swords into plowshares and their spears into pruning hooks, and know of no war. They render unto Caesar the things that are Caesar's and unto God the things that are God's. Their sword is the sword of the Spirit which they wield with a good conscience through the Holy Ghost."[96]

In time the followers of Menno Simons gained in influence, while branches of the Anabaptist movement which did not follow the principle of non-resistance died out. Here and there other non-resistant groups such as the Hutterites and the Moravian Brethren continued.[97]

Ultimately the Mennonites found their way into several parts of Europe, from the North Sea to Russia, in their search for a home where they might be free from persecution. The founding of Germantown in the new Pennsylvania colony in 1683 marked the beginning of a migration which in the years that followed brought the more radical of them to America.[98] With the coming of conscription in Europe, those who held most strongly to their non-resistant principles came to the United States to escape military service. Those who remained in Europe gradually gave up their opposition to war, but those in America have largely maintained their original position.[99]

Today they still refrain from opposing evil, and believe in the separation of church and state, which to them means a refusal to hold office and, in many cases, to vote or to have recourse to the courts. They pay their taxes and do what the state demands, as long as it is not inconsistent with their duty to God. In case of a conflict in duty, service to God is placed first. Since they do not believe that it is possible for the world as a whole to become free of sin, they maintain that the Christian must separate himself from it. They make no attempt to bring about reform in society by means of political action or other movements of the sort which we have considered under non-violent direct action.[100]

Since the term "pacifist" has come into general use to designate those opposed to war, the Mennonites have usually made a distinction between themselves as "non-resistants" and the pacifists, who, they claim, are more interested in creating a good society than they are in following completely the admonitions of the Bible. They also disclaim any relationship to such non-resistants as Garrison or Ballou, even though these men reached substantially the same conclusion about the nature of the state, or with Tolstoy who even refused to accept the support of the state for the institution of private property. The American non-resistants they regard primarily as reformers of human society, and Tolstoy as an anarchist who rejected the state altogether, rather than accepting it as a necessary evil.[101] In so far as the Mennonites have used social influence at all, it has been through the force of example, and in their missionary endeavors to win other individuals to the same high principles which they themselves follow.
