The Topeka, Kansas-based Westboro Baptist Church, known for coining the phrase “God hates fags” and picketing the funerals of fallen soldiers, has asked to intervene in a case challenging Kansas' ban on gay marriage.

Kansas is the lone state resisting two separate Tenth Circuit Court of Appeals rulings striking down gay marriage bans in Oklahoma and Utah. The court's rulings took effect earlier this month after the Supreme Court refused to hear appeals in the cases.

The ACLU has asked a federal judge in Kansas City to force the state to comply with the rulings and allow gay and lesbian couples to marry in Kansas. The ACLU is representing two lesbian couples who wish to marry in Kansas but were denied marriage licenses. Last-minute briefs in the case are due Monday.

In its petition, Westboro officials said that allowing gay couples to marry would “destroy Kansas.”

“If this Court requires Kansas officials to treat what God has called abominable as something to be respected, revered, and blessed with the seal-of-approval of the government, that will cross a final line with God,” the document states. “The harm that will befall this state, when the condign destructive wrath of God pours out on Kansans is the ultimate harm to the health, welfare and safety of the people.”

Lawyers representing Westboro told U.S. District Judge Daniel Crabtree that the church has a “vital interest in what the courts rule regarding this issue, as it directly impacts their religious practices, beliefs, preachments, picketing, association and speech, as well as the wellbeing of their fellow man.”

Crabtree dismissed a similar request to intervene in the case by a straight couple who claimed that allowing gay couples to marry would be tantamount to seizing their marriage property.
