Though not really the point of his post, Hellmut of at Beyond Ourselves brought up an interesting note in his Sex and Salvation post.
One finds the following point made in the Official Declaration 2:
In early June of this year, the First Presidency announced that a revelation had been received by President Spencer W. Kimball extending priesthood and temple blessings to all worthy male members of the Church.
In contrast, Official Declaration 1 has this to say:
Inasmuch as laws have been enacted by Congress forbidding plural marriages, which laws have been pronounced constitutional by the court of last resort, I hereby declare my intention to submit to those laws, and to use my influence with the members of the Church over which I preside to have them do likewise.
There is nothing in my teachings to the Church or in those of my associates, during the time specified, which can be reasonably construed to inculcate or encourage polygamy; and when any Elder of the Church has used language which appeared to convey any such teaching, he has been promptly reproved. And I now publicly declare that my advice to the Latter-day Saints is to refrain from contracting any marriage forbidden by the law of the land.
Can we say that both of these declarations, given their different natures (one based in revelation one in response to legal pressures), are equal in authority?
