Johann Christoph Arnold (born 1940) is a Christian writer, pastor, and marriage counselor who served as Elder of the Bruderhof Communities between 1983 and 2001. His grandfather, Eberhard Arnold, founded the Bruderhof Communities in 1920 and died in 1935. Before Johann became Elder, the position was held by Heinrich Arnold, his father. In 1995, Johann Arnold wrote an open letter criticizing the Hutterites, a group with which the Bruderhof Communities had been united since 1974, and this letter, which was especially critical of the Hutterite leadership, finalized a split between the two groups that had begun in the early 1990s. Arnold founded Breaking the Cycle of Violence, a conflict resolution program. He opposes remarriage following divorce. He is married to Verena Arnold, who proofreads all of his book manuscripts before they are published. The subjects of his books include marriage, sexual intercourse, parenting, conflict resolution, and death anxiety. Many of these books have become bestsellers and he gives large numbers of copies away for free.
