The Supreme Court has yet to announce its decision on the two gay marriage cases. However, that has not stopped conservatives from pledging to defy marriage equality, if the high court makes a pro-LGBT decision.

In a letter released Thursday, more than 200 conservative activists — ranging from the Catholic League’s Bill Donohue to Oklahoma State Rep. Sally Kern (R) — vowed to ignore any ruling in favor of same-sex couples. The group of endorsers, signing under the moniker of Freedom Federation, is composed of anti-LGBT Christian conservatives, many of whom have fallen from prominence in recent years.

“We stand together as Christians in defense of marriage and the family and society founded upon them,” the letter reads.

Liberty Counsel head Mat Staver and Deacon Keith Fournier, the editor-in-chief of Catholic Online, drafted the “Marriage Solidarity Statement” that attacks marriage equality by invoking “Natural Moral Law” and questioning the authority of the Supreme Court.

“This Natural Moral Law gives us the norms we need to build truly human and humane societies and govern ourselves. It should also inform our positive law or we will become lawless and devolve into anarchy,” the statement warns. “Redefining the very institution of marriage is improper and outside the authority of the State. The Supreme Court has no authority to redefine marriage.”
