Seventh-day Adventist Church Stucture
The local church is made up of individual believers
The local conference, or local field/mission, is made up of a number of local churches in a state, province, or territory
The union conference, or union field/mission, is made up of conferences or fields within a larger territory (often a grouping of states or a a whole country)
The General Conference, the most extensive unit of organization, is made up of all unions/entities in all parts of the world. Divisions are sections of the General Conference, with administrative responsibility for particular geographical areas.
Each level is "representative." That is, it reflects a democratic process of formation and election. Local churches elect their own officers and church boards by majority voting. Churches elect delegates to the conferences which meet "in session" every two or three years. Executive authority between sessions is exercised by the Conference Executive Committee and the executive officers (normally President, Secretary and Treasurer), all of whom are elected by the session.
