The history, within Mormonism, of polygamy, and the denial of the priesthood to blacks of African descent, share a number of interesting parallels which raise some rather serious questions. The most obvious question is whether there was ever any revelation to end either practice. Additionally, there is no more reason to think that Mormon leaders have actually renounced their views about dark skin being a curse from God than there is to think they have renounced the belief that polygamy was a divine principle ordained of God.
In both cases — polygamy, and banning blacks from the priesthood — Mormon leaders taught that the practice was instituted by God and could not be changed by themselves. Refusal to obey either principle would precipitate divine punishment.(1) Mormon leaders also claimed that both practices were based on eternal, divine doctrine, as revealed in scripture given through the prophet Joseph Smith.(2)
Mormon leaders say there was also revelation from God requiring an end of both practices (see material following the Manifesto, in Official Declaration — 1, and, Official Declaration — 2). However, neither of the Official Declarations by which these practices were declared ended actually contains any such revelation. No actual text of either revelation has ever been printed.
Other "revelations" were added to Mormon scripture during the 1970s, and made into additional Sections in the Doctrine & Covenants. The Church has not so dignified either of the documents ending polygamy and the priesthood ban on blacks. This leaves the unavoidable impression that both the "Official Declarations" are not really viewed by the Church Authorities as revelation or scripture like the rest of the Church's standard works.
The revelation authorizing polygamy — indeed, commanding it, under threat of damnation — is still printed without modification, as scripture (D&C 132), binding on the consciences of Mormons. All of the passages used to support the former discrimination policy against blacks are likewise still printed and affirmed as scripture — the Word of God — by the Mormon Church.
In both cases, no acknowledgement has ever been made that either the doctrine or practice was actually wrong. To the contrary, the principle of plural marriage is still taught in the Mormon Church as a true principle — a principle supposedly practiced by God in the Celestial Kingdom, now, and that will yet be practiced there by Mormons as well. In the case of the priesthood ban against blacks, only the practice is acknowledged to have been changed.
Mormon leaders have adopted the position that the plural marriage "doctrine" is true, but for the sake of the progress of "the gospel" in the world, it is not currently "practiced." Could it be that Mormon Church leaders have merely stopped "the practice" of denying priesthood on the basis of race, while still believing "the doctrine" that skin color is a curse from God, and thus that blacks are still cursed by God? Do they truly regard ordination of blacks to the priesthood as valid and upheld by God, or as only an empty form necessary to avoid an obstacle to the progress of Mormonism in the world? Could it be that neither they nor their God have ever really changed their minds on this issue any more than they changed their minds about polygamy? If there actually were any revelations ending either practice, why have they never been published?
