Organizational structure is currently divided into episcopal districts (by state or country), commonly called councils or diocese. Each of these are headed by a diocesan bishop, who is appointed by the Bishop's Board. A diocesan bishop can have as many as three assistants, called suffragan bishops. Suffragan bishops hold only the authority given them by the diocesan bishop. Typically they will have authority over a region or part of a state. Reporting under the suffragan bishop is the office of district elder, who oversees and assists the elders (pastors and their churches) in his district.
