Doctrine & Covenants 134
"A Declaration of Beliefs"
"We believe that governments were instituted of God for the benefit of man."
"We believe that all governments necessarily require civil officers" (but they should be equitable and just).
"We believe that all men are bound to sustain and uphold the respective governments in which they reside. . . . Sedition and rebellion are unbecoming."
"All men should step forward" and work towards peace and tranquility, bringing offenders to justice, and encouraging leaders to be righteous.
It's nice to be reminded that good citizens are proactive.
