The following is excerpted from the Church's Web site, lds.org:
On May 25, the First Presidency sent a letter to priesthood leaders in the United States, reaffirming the Church's support of marriage between a man and a woman as the only acceptable marriage relationship, and urging members to "express themselves on this urgent matter to their elected representatives in the Senate."
On June 6, 2006, the United States Senate will vote on a proposed amendment to the U.S. Constitution defining marriage as consisting "only of the union of a man and a woman" and that "marriage or the legal incidents thereof" should not be "conferred upon any union other than the union of a man and woman."
In the May 25 letter, the First Presidency reiterated "The Family: A Proclamation to the World," stating: "In that proclamation we said: 'We call upon responsible citizens and officers of government everywhere to promote those measures designed to maintain and strengthen the family as the fundamental unit of society.' "
In April 2006, the Church added its voice to other religious bodies in the United States calling for a constitutional amendment designed to protect the traditional institution of marriage. Elder Russell M. Nelson of the Quorum of the Twelve Apostles, representing the Church, added his signature to a letter signed by religious leaders across the nation that called for a constitutional amendment establishing the definition of marriage as the exclusive union of one man and one woman.
"We are convinced that this is the only measure that will adequately protect marriage from those who would circumvent the legislative process and force a redefinition of it on the whole of our society," states the letter.
