Republican presidential candidate Rick Santorum said Friday that the United States will never be a great nation so long as gay and lesbian couples can marry and abortion remains legal.

Santorum, a vocal opponent of LGBT rights, made his remarks during a speech at this weekend's Values Voter Summit, which is sponsored by FRC Action, the legal arm of the Christian conservative Family Research Council (FRC).

“America is never going to be a great country if we're a country that kills our children in the womb, ever!” Santorum said. “We are never going to be blessed by God if we're a country that kills our children in the womb. We are never going to be a great country if we allow for the destruction of the American family, that's what's happened over the last 50 years.”

“And thank you for coming here. And for standing for truth. Standing for what you know is right and best for this country,” he added.

Also at the conference on Friday, FRC President Tony Perkins and Liberty Counsel Chairman Mat Staver presented Kentucky clerk Kim Davis with the Cost of Discipleship Award for refusing to comply with the U.S. Supreme Court's summer ruling striking down gay marriage bans in all 50 states.
