The Republican National Committee passed resolutions Friday reaffirming its commitment to defining marriage as a union solely between one man and one woman, and calling on the Supreme Court to “uphold the sanctity of marriage” as it weighs cases involving same-sex marriage.

The measures were adopted unanimously and without discussion as part of a slate of resolutions at the RNC’s spring meeting in Los Angeles, a committee spokeswoman said.

The moves come amid widespread soul-searching within the GOP over same-sex marriage, which has rapidly gained support among Democrats and independents but is opposed by most Republicans, polls show. Social conservatives sent a letter to RNC Chairman Reince Priebus this week threatening to decamp if the party did not reaffirm its commitment to their issues.

One of the resolutions approved Friday affirms the committee’s “support for marriage as the union of one man and one woman, and as the optimum environment in which to raise healthy children for the future of America.”

Another involves the Supreme Court, which recently heard arguments in cases focused on California’s same-sex marriage ban and the federal Defense Of Marriage Act, which prevents same-sex married couples from receiving certain federal benefits.

“The Republican National Committee implores the U.S. Supreme Court to uphold the sanctity of marriage in its rulings on California’s Proposition 8 and the Federal Defense of Marriage Act,” the RNC’s resolution states.

In another section, the committee also reaffirmed the “core values” of its 2012 platform, including “that marriage, the union of one man and one woman must be upheld as the national standard.”

The “core values” portion was sponsored by Michigan RNC member Dave Agema, who caused a stir when he recently posted an article to his Facebook page referencing the “filthy” lifestyle of homosexuals.

“We have won the battle, and I will have nothing more to say on this matter,” Agema said in a statement Friday.
