"We will not obey."

That's the blunt warning a group of prominent religious leaders is sending to the Supreme Court of the United States as they consider same-sex marriage.

"We respectfully warn the Supreme Court not to cross that line," read a document titled, Pledge in Solidarity to Defend Marriage. "We stand united together in defense of marriage. Make no mistake about our resolve." 

"While there are many things we can endure, redefining marriage is so fundamental to the natural order and the common good that this is the line we must draw and one we cannot and will not cross," the pledge states.

The signees are a who's who of religious leaders including former Arkansas Gov. Mike Huckabee, former U.S. Senator Rick Santorum, National Religious Broadcasters president Jerry Johnson, Pastor John Hagee, and Franklin Graham, president and CEO of the Billy Graham Evangelistic Association and Samaritan's Purse.

The pledge was co-drafted by Deacon Keith Fournier, a Catholic deacon, and Mat Staver, the founder of Liberty Counsel. Also involved in the document were Rick Scarborough, the president of Vision America Action and James Dobson, the founder of Family Talk Radio. 

"We're sending a warning to the Supreme Court and frankly any court that crosses the line on the issue of marriage," Staver told me.

He said that once same-sex marriage is elevated to the level of protected status – it will transform the face of society and will result in the "beginning of the end of Western Civilization."

"You are essentially saying that boys and girls don't need moms and dads – that moms and dads are irrelevant," Staver said. "Gender becomes pointless when government adopts same-sex marriage. It creates a genderless relationship out of a very gender-specific relationship. It says that it doesn't matter and that two moms or two dads are absolutely equivalent to a mom and a dad."
