Laura Fotusky has quit her job as town clerk of Barker, New York rather than sign marriage licenses for gay and lesbian couples, reported.

New York last month became the sixth – and most populous – state to legalize gay marriage after Governor Andrew Cuomo signed a marriage bill approved by lawmakers. The law takes effect on Sunday, July 24, and several cities, including New York City, have announced they'll open on the law's first day.

Fotusky said she quit because of her faith.

“I would be compromising my moral conscience by participating in licensing same-sex couples,” Fotusky said. “I had to choose between my job and my god.”

The 56-year-old Fotusky posted her resignation letter on the website of New Yorkers for Constitutional Freedoms, a group that campaigned against the law.

“The Bible clearly teaches that God created marriage between male and female as a divine gift that preserves families and cultures,” she wrote. “Since I love and follow Him, I cannot put my signature on something that is against God.”

Fotusky's last day is July 21.
