FRANKFORT, Ky. (AP) – The first test of the U.S. Supreme Court’s ruling legalizing gay marriage begins Monday in a Kentucky courtroom, where a county clerk plans to argue that her Christian faith prevents her from issuing same-sex marriage licenses.

The case is reviving memories of the Supreme Court’s 1967 ruling in Loving vs. Virginia striking down laws across the country forbidding interracial marriage. Waves of resistance that rippled across the South then took years to dissipate.

Legal experts suggest history might hint at how the coming months will unfold, as some defiant clerks refuse to abide by the gay marriage ruling.

The American Civil Liberties Union filed a lawsuit against Rowan County Clerk Kim Davis. Other clerks have rallied behind her, demanding the government protect Christians from having to issue gay marriage licenses.
