LOUISVILLE, Ky. — Benjamin Moore and Tadd Roberts wore matching tuxedos to the county clerk’s office in Louisville to get married Friday, and the mayor greeted them with a bottle of champagne.

They were among a rush of gay couples across the South and Midwest who celebrated the Supreme Court’s ruling legalizing same-sex marriage with spontaneous weddings. They were young and old, they wore gowns and suits or T-shirts and jeans, they kissed and waved flags that read “love wins.”

“It’s just been incredible and historic and amazing to live this moment,” Moore said.

But the reaction wasn’t as welcoming in some of the 14 states that had been the last holdouts against same-sex marriage, creating confusion as some officials embraced the ruling and others rebuffed it.

Alabama Chief Justice Roy Moore, who has long fought against same-sex marriage, said states can fight the ruling, as they have decisions allowing slavery or abortion, and predicted that it would spark a national backlash from Christian conservatives.

“They’ve just disregarded everything that precedent holds, and they’ve destroyed the foundation of our country which is family,” Moore said.

In rural Alabama, Pike County Probate Judge Wes Allen said he would stop issuing all marriage licenses to avoid having to give them to gay couples. Allen said Alabama law gives judges the option of granting licenses, and “I have chosen not to perform that function.”

Governors in Louisiana, Mississippi and Texas also railed against the ruling. And clerks in some of the affected states refused to issue licenses, citing a three-week grace period allowed by the Supreme Court or forms now out of date that specify “bride” and “groom.”

But by Friday afternoon, couples had received licenses in all but one of the 14 states, according to the Human Rights Campaign. In Louisiana, where Republican Gov. Bobby Jindal is running for the White House as a conservative Christian, same-sex couples were turned away.

“It was kind of bittersweet,” said Earl Benjamin, who waited with his partner for hours for a license and was finally told that the state’s ban on same-sex marriage remained intact — for now.

In Texas, many counties held off on issuing same-sex marriage licenses until receiving guidance from Republican Attorney General Ken Paxton, who scolded the Supreme Court but left counties in limbo for hours.

Mississippi Attorney General Jim Hood said Friday that same-sex marriages cannot take place immediately. But amid the confusion over when weddings should legally begin, three couples received their marriage licenses in Hattiesburg, and took their vows on the courthouse steps.
