Jim Obergefell, the lead plaintiff in the case that toppled gay marriage bans nationwide, has penned an open letter to Kentucky county clerk Kim Davis.

Davis, the elected clerk of Rowan County, last month spent five days in jail for refusing to comply with the Supreme Court's summer ruling striking down gay marriage bans in all 50 states. Davis said that issuing marriage licenses to gay and lesbian couples would violate her conscience.

In his open letter, published Wednesday by the American Civil Liberties Union (ACLU), Obergefell pleads with Davis to “not stand in the way of others seeking their legal right to have their love recognized.”

'”You're imposing the same indignities on couples in Rowan County that John and I suffered when Ohio would not legally recognize us as a married couple,” he said of his late husband, John Arthur. “Thankfully, the law is now changed so that nobody should ever have to experience the injustice that John and I endured.”

“No one is above the law, Kim, not even you,” he wrote.

Obergefell added that it's not fair for Davis to judge: “It's your job to simply do your job. Issuing a marriage license at work is not a personal endorsement of my marriage any more than recording a deed is an endorsement of home ownership.”

This week, news broke that Davis met privately with Pope Francis during his recent visit to the United States. While the Vatican has confirmed that the meeting took place, officials have not said why it wasn't made public.
