Mitt Romney on Saturday reiterated his opposition to gay marriage just days after President Barack Obama endorsed the institution.

Romney on Saturday addressed the 2012 graduating class at conservative Christian Liberty University, which was founded by the late preacher Jerry Falwell.

“Culture – what you believe, what you value, how you live – matters,” Romney told graduates. “Now as fundamental as these principles are, they may become topics of Democratic debate from time to time. So it is today with the enduring institution of marriage.”

“Marriage is a relationship between one man and one woman,” he added to rousing applause from those gathered in the school's football stadium in Lynchburg, Virginia.

Romney later added: “The American culture promotes personal responsibility, the dignity of work, the values of education, the merit of service, devotion to a purpose greater than self, and at the foundation, the preeminence of the family.” (The video is embedded in the right panel of this page.

The announcement that Romney, a Mormon, would speak at Liberty caused an uproar.
