Attorneys for Rowan County Clerk Kim Davis say the pope met privately with her and her husband during the pope's visit to the United States last week.
Pope Francis met with the couple at the Vatican Embassy in Washington, D.C., on Thursday, according to a news release issued by the Liberty Counsel on Tuesday.
The pontiff is said to have thanked Davis for her courage and encouraged her to "stay strong." He also asked Davis to pray for him, and she asked him to pray for her.
"I was humbled to meet Pope Francis. Of all people, why me?" Davis said in a statement. "... I am just a county clerk who loves Jesus and desires with all my heart to serve him."
During the pope's return trip to Rome, reporters aboard his plane asked him about Davis' case.
While he responded that he did not know the details of the case, he affirmed the right to conscientious objection.
"It is a right. And if a person does not allow others to be a conscientious objector, he denies a right," Francis said.
Davis, an Apostolic Christian, was jailed for refusing to issue marriage licenses after the Supreme Court ordered that same-sex couples be afforded them.
