Christian leader Albert Mohler said Christians should view the 2012 election as a "catastrophe" for moral issues, saying the election reflects a trend of growing secularism in American society.
Mohler is president of Southern Baptist Theological Seminary, the leading seminary for the country's largest Protestant denomination.
He cited a recent study that indicates 20 percent of Americans have no religious preference. Read more here.
"The election of President Obama returns a radically pro-abortion president to the White House, soon after he endorsed same sex-marriage," Mohler said.
Mohler said the president will probably have the opportunity to appoint one or more Supreme Court justices in his second term.
"Clearly, we face a new moral landscape in America, and huge challenge to those of us who care passionately about these issues," he continued. "We face a worldview challenge that is far greater than any political challenge, as we must learn how to winsomely convince Americans to share our moral convictions about marriage, sex, the sanctity of life, and a range of moral issues."
"This will not be easy," he added. "It is, however, an urgent call to action."
