The Church of Jesus Christ of Latter-day Saints announced Sunday that what has been known as the Family and Church History Headquarters Mission will now be known as the Utah Salt Lake City Headquarters Mission. According to Mormon Newsroom, this mission has the most missionaries of any in the church.

Elder Craig C. Christensen announced the change at a special meeting for missionaries in Salt Lake City.

The change is significant because the missionaries' service will extend beyond family history work to include service “with the Temple Department, military relations, security, building maintenance and other areas,” Mormon Newsroom explains. The mission currently includes service missionaries, full-time missionaries, senior couples and single sister missionaries. In the new mission, senior missionaries will have the opportunity to serve in local branches and inner-city areas outside of normal business hours.

President Warren G. Tate will serve as mission president with President Clark Larson and President Randy Hansen serving as counselors.
