While all bishops are attached to a congregation (in the sense that every member of the church has a home congregation), bishops are not congregational officers, but preside as financial officers over larger jurisdictions, or support those who do. For example, each mission center will have a bishop in charge of all the finances of that area, who may be assisted by other bishops. Likewise, some nations have a national bishop, and historically, stakes also had bishops. Consequently, this makes the office of bishop somewhat uncommon. In recent years, some mission centers have had multiple bishops in order to help promote the various ministries associated with good stewardship.
