The Church of Jesus Christ of Latter-day Saints has filed a pair of briefs with the U.S. Supreme Court, asking it to uphold California’s Proposition 8 and the federal Defense of Marriage Act.

The briefs were drafted by lawyers for the LDS Church here in Utah and filed Jan. 29 before the nation’s top court on behalf of the National Association of Evangelicals, the Southern Baptist Convention, the Lutheran Church-MIssouri Synod, the Romanian-American Evangelical Alliance of North America, Truth in Action Ministries, and the Mormon Church.

“Our theological perspectives, though often differing, converge to support the proposition that the traditional, opposite-sex definition of marriage in the civil law is not only constitutional but essential to the welfare of families, children, and society,” Von Keetch of the Utah-based firm Kirton McConkie, wrote in the DOMA brief.

... “The people of California violated no one’s civil rights when they adopted Proposition 8. Their twice-expressed preference for the traditional definition of marriage over an untested rival conception was thoroughly rational. It is therefore thoroughly constitutional,” Keetch wrote in the Prop. 8 brief.
