The handbooks help maintain the integrity of policies, procedures, and programs of a church that is experiencing rapid growth around the world.
"Our membership has been increasing since the Church was organized in 1830. And it will continue to grow with thousands of units throughout the world," said President Thomas S. Monson during the November 2010 worldwide leadership training meeting. "It would be nearly impossible to maintain the integrity of the policies, procedures, and programs of the Church without these handbooks."
