In trying all matters of doctrine, to make a decision valid, it is necessary to obtain a unanimous voice, faith, and decision. In the capacity of a Quorum, the three first presidents must be one in their voice—the Twelve Apostles must be unanimous in their voice, to obtain a righteous decision upon any matter that may come before them, as you may read in the Doctrine and Covenants. The Seventies may decide upon the same principle. Whenever you see these Quorums unanimous in their declaration, you may set it down as true. Let the Elders get together, being faithful and true; and when they agree upon any point, you may know that it is true.
