Washington (CNS) -- Traditional marriage between one man and one woman is really about the good of children and families, and the "good of families" is about "the good of society," said the chairman of the U.S. bishops' Subcommittee for the Promotion and Defense of Marriage.
"That's in the natural order, that's the way marriage exists in nature, that's why marriage is important for the social good," said Archbishop Salvatore J. Cordileone of San Francisco.
"Nature promotes a child having a father and a mother. There's no way a child could come into the world other than with a father and a mother," he added. The Catholic Church opposes same-sex marriage "because we favor preserving the definition of marriage in the law as it exists naturally," he told Catholic News Service.
"What we're really opposed to is marriage redefinition. Our opponents in the debate ... favor not expanding the right of marriage but redefining it to be something different from what it is to include the union of two people of the same sex," he said.
"One could ask, 'Well why should it stop there, why can't it include other types of unions, such as multiple partners?'" Archbishop Cordileone spoke to CNS March 26 in Washington.
That morning, he addressed the March for Marriage rally on the National Mall. The U.S. Conference of Catholic Bishops was a co-sponsor of the event.
