Alabama Supreme Court Chief Justice Roy S. Moore headlined an Austin rally on Monday calling for “Biblical marriage.”

Marriage equality opponents staged the rally to show support for passage of the Preservation of Sovereignty and Marriage Act, a Republican bill which seeks to prohibit county clerks from issuing marriage licenses to gay and lesbian couples and would require Texas courts to dismiss challenges to the state's ban on gay marriage. The bill is scheduled for a hearing Wednesday.

Attending the rally were Lt. Governor Dan Patrick and Attorney General Ken Paxton.

“No court has authority to redefine what God proposed in Genesis,” Moore told the crowd, adding that the Bible defines marriage as a heterosexual union.

In comments to the AP, Moore said that he was in the Texas Capitol to teach the law.

“I'm teaching that federal courts have no authority in this area,” he said.

Moore injected himself into the marriage debate in Alabama, ordering state probate judges – who issue such licenses – to ignore a federal judge's ruling striking down Alabama's ban.
