Journal of Discourses 4:368; “How easy it would be for your leaders to lead you to destruction, unless you actually know the mind and will of the Spirit yourselves. That is your privilege. And when you testify in this public congregation, or in your prayer meetings, testifying of the things of God that you know and understand, you are at liberty to speak freely upon those things which you believe.” – Brigham Young, June 28, 1857, Salt Lake City
