The church holds its general conference, though Joseph Smith, Jr. and Frederick G. Williams are absent. The church body unanimously adopts and canonizes the Doctrine and Covenants as compiled by the committee of Smith, Williams, Oliver Cowdery, and Sidney Rigdon. Among the new revelations is D&C 134, concerning the relationship between church, government, and individuals, asserting that governments are instituted by God for the benefit of man; that government should protect the freedom of men to worship as they please; that all men should uphold their government and laws; that churches should not exercise civil powers; and that individuals are justified in defending themselves and their property. Another section 101 was included that condemns the practice of polygamy.
