It is the organization of The United Methodist Church that creates a structure for connectionalism. The United Methodist Church is intentionally decentralized and democratic. Clergy and laity alike help determine the ministry and workings of The United Methodist Church through their actions in their local churches, annual conferences, general agencies and through petitions and resolutions they send to General Conference, and through the voting delegates who go to General Conference, the only body that can set official policy for the church. It is individuals, the people called United Methodists, who make possible the connection of hearts, minds, hands and lives as the body of Christ around the world.
Most individuals have their initial contact with the denomination in the local church. Some local church members don't realize that they are part of a bigger whole-the connection: an annual conference, a jurisdiction, the General Church, and churches and annual conferences around the world.
Groups of churches in a geographic area are organized to form a district, somewhat similar to the way cities and towns are organized into counties. Often, churches in a district will work together to provide training and mission opportunities.
Each district is led by a district superintendent (“DS”) an elder appointed by the bishop, usually for a six-year term. The DS oversees the ministry of the district’s clergy and churches, provides spiritual and pastoral leadership, works with the bishop and others in the appointment of ordained ministers to serve the district’s churches, presides at meetings of the charge conference, and oversees programs within the district.
