Eberhard Arnold (26 July 1883 – 22 November 1935) was a German theologian and Christian writer. He was the founder of the Bruderhof in 1920.
Arnold was born in Königsberg, East Prussia, Germany, the third child of Carl Franklin and Elizabeth (Voight) Arnold. His father was a doctor of theology and philosophy, and his paternal grandfather was a pastor and missionary of the Evangelical State Church of Prussia's older Provinces. Eberhard Arnold's life as a youth was unconventional. In 1899 at age 16, Arnold experienced an inner change, which he acknowledged as God's acceptance and the forgiveness of sins, and felt a calling to "go and witness to my truth."
After he finished school, Arnold studied education, philosophy, and theology in Breslau, Halle, and Erlangen. He engaged in Christian youth work and in evangelism among the poor through the Salvation Army. While in Halle, he became part of the German Student Christian Movement, and its General Secretary. In 1907 he and his wife von Hollander seceded from the Eva state church Evangelische Kirche. His work with the Salvation Army increased his sympathy for the oppressed classes of people and strengthened his stand for preaching conversion and salvation. Here in Halle, he also met Emmy von Hollander and married her in 1909.
Arnold was a sought-after speaker in early 20th-century Germany. He became troubled by the church's connection to the state, and in 1908, at age 25, Arnold was baptized and left the Protestant state church. He began to thoroughly investigate Anabaptist history, which apparently influenced his taking his life and ministry in a radical direction. In 1915 he became editor of Die Furche (The Furrow), the periodical of the Student Christian Movement, and editor of the Das Neue Werk (New Venture) Publishing House in Schlüchtern, Germany in 1919.
At age 37, he abandoned middle-class life. It was then, in 1920, that he moved with his wife and children to the village of Sannerz in central Germany, and founded a community with seven adult members and five children. Here they would attempt to put into practice what Eberhard Arnold believed the Holy Spirit had revealed to him. The community ethic was based on Jesus' Sermon on the Mount. The community experienced both trouble and growth, but by the mid-1920s the Sannerz farm was too small. In 1926, they bought a farm in the Fulda district and established the Rhön Bruderhof. When Arnold discovered that Hutterite communities still existed in North America, he contacted them and engaged in a long period of correspondence. In 1930 he traveled to America and stayed for about a year, visiting all the communities of Hutterian brethren in the United States and Canada. In December of that year, he was commissioned by them as a missionary to Europe.
