Tony Perkins, president of the Christian conservative Family Research Council (FRC), has blasted a federal appeals court's affirmation of a lower court's ruling striking down Oklahoma's ban on gay marriage.

A divided three-judge panel of the Tenth Circuit Court of Appeals in Denver declared Oklahoma must allow gay and lesbian couples to marry. Last month, the same panel upheld a ruling knocking down Utah's ban. Utah officials have since announced they'll ask the Supreme Court to review the case.

Perkins, a long-time opponent of gay rights, suggested the mounting rulings in favor marriage equality would lead to a citizens revolt.

“Two appeals court judges in imposing marriage redefinition have substituted their own ideology for the right of the people to preserve marriage,” Perkins said in a statement. “This divided court has swept away the 1,668,513 voters in Utah and Oklahoma who exercised their democratic right to preserve marriage in their respective state constitutions.”

“Voters have a right to preserve natural marriage as the best means of providing what every child deserves: a mom and a dad.”

“The Left has long believed packing the federal courts with liberal jurists is the means of fulfilling a radical social agenda, as the American people refuse to endorse that agenda at the polls or through their elected representatives. However, by such a radical departure from natural law and human history, these activist judges are undermining the legitimacy of the courts in the eyes of a majority of Americans. These judges may want to take America over the cultural cliff, but don't be surprised when more and more Americans refuse to follow,” he added.
