The Republican National Committee passed resolutions Friday reaffirming its commitment to defining marriage as between a man and a woman, and calling on the Supreme Court to "uphold the sanctity of marriage" as it weighs rulings on two landmark cases involving gay marriage.

At the RNC's spring meeting in Los Angeles, committee members adopted a slate of resolutions unanimously and without discussion, a committee spokeswoman said.

One of the resolutions 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."
