1853: Brigham Young speaks concerning Mormons who say the judgment of living prophets “is superior to mine, and consequentîy I let you judge for me." He says that such Latter-day Saints do not possess “the true independence of heaven," and consequently “will never be capable of entering into the celestial glory, to be crowned as they anticipate; they will never be capable of becoming gods.” Young says that Mormons should depend on “the influences of the Holy Spirit” and “their own understanding.”

1872: unsuccessful statehood convention which drafts a proposed constitution that allows Congress to add an anti-polygamy clause. Of this, his non-Mormon friend Thomas L.

As regards the actual abandonment of polygamy, that is a question between you and your God. And I have naught to say on it. But Duplicity, I see, without a shadow, will not be good policy for you."
