Christian anarchism is a movement in political theology that claims anarchism is inherent in Christianity and the Gospels. It is grounded in the belief that there is only one source of authority to which Christians are ultimately answerable, the authority of God as embodied in the teachings of Jesus, and thus rejects the idea that human governments have ultimate authority over human societies. Christian anarchists denounce the state as they claim it is violent, deceitful and, when glorified, idolatrous. Christian anarchists hold that the proper relationship between God and people is the "Reign of God" in which human relationships would be characterized by divided authority, servant leadership, and universal compassion rather than the hierarchical, authoritarian structures normally attributed to religion.
More than any other Bible source, the Sermon on the Mount is used as the basis for Christian anarchism. Most Christian anarchists are pacifists and reject the use of violence, such as war.Leo Tolstoy's The Kingdom of God Is Within You is often regarded as a key text for modern Christian anarchism.
Jacques Ellul, a French philosopher and Christian anarchist, notes that the final verse of the Book of Judges (Judges 21:25) states that there was no king in Israel and that "everyone did as they saw fit". Subsequently, as recorded in the first Book of Samuel (1 Samuel 8) the people of Israel wanted a king "so as to be like other nations". God declared that the people had rejected him as their king. He warned that a human king would lead to militarism, conscription and taxation, and that their pleas for mercy from the king's demands would go unanswered. Samuel passed on God's warning to the Israelites but they still demanded a king, and Saul became their ruler. Much of the subsequent Old Testament chronicles the Israelites trying to live with this decision.
