Brigham Young teaches that, if ancient prophets and apostles were asked about their doctrine of deity, there would be differences of theological opinion.
Brigham Young, "Saints Subject to Temptation—True Riches, Virtue, and Sanctification—"Mormonism"—Gladdenites, Apostles, and Saints—Devils Without Tabernacles," Journal of Discourses, 26 vols. (Liverpool: F.D. Richards, 1855), 2:123
Were the former and Latter-day Saints, with their Apostles, Prophets Seers, and Revelators collected together to discuss this matter [the nature of Deity], I am led to think there would be found a great variety in their views and feelings upon this subject, without direct revelation from the Lord. It is as much my right to differ from other men, as it is theirs to differ from me, in points of doctrine and principle, when our minds cannot at once arrive at the same conclusion.
