Mitt Romney is telling students at a Christian university that marriage is between one man and one woman.

At Liberty University's commencement today in Lynchburg, Va., Romney calls marriage an "enduring" institution that's reserved for one man and one woman. He also says that culture matters, defining it as "what you believe, how you live, what you value."

The crowd cheered Romney's comments, which come days after President Barack Obama embraced same-sex marriage.

Romney avoided talking about his own faith but says Judeo-Christian values have driven American success.

Romney says that students at the university will bring "moral certainty" and "clear standards" to their jobs and lives. He also says that America has trusted in "God, not man," since its founding.
