First-grade teacher Molly Shumate ended her 14-year career to support her 22-year-old gay son.

Shumate is among the handful of teachers who have refused to sign the Cincinnati Archdiocese's teacher contract.

Part of the contract prohibits “public support of or homosexual lifestylfe.”

“It's sad,” she told CNN. “And my spirit is broken.”

In comments to, Shumate added: “If my son were to say to me, 'Will you go somewhere with me that is supported or run by gays and lesbians,' I would have to tell him no, according to that contract. And if my picture was taken, what would happen?”

“For me to sign this [contract], I feel like I would be telling my son I've changed my mind, that I don't support him as I did. And I won't do that.”

Roughly 14 months ago, the Archdiocese of Cincinnati removed an assistant principal for expressing his support for marriage equality.

Mike Moroski wrote in a January 27, 2013 post that he believes “that gay people SHOULD be allowed to marry.”

“Ethically, morally and legally I believe this. I spend a lot of my life trying to live as a Christian example of love for others, and my formation at Catholic grade school, high school, 3 Catholic Universities and employment at 2 Catholic high schools has informed my conscience to believe that gay marriage is NOT something of which to be afraid,” Moroski wrote.

According to NBC affiliate WLWT, a lay Catholic group has launched a billboard campaign to protest the contract's expanded morality clause.

Twelve billboards scattered throughout the community ask, “Would Pope Francis sign the new Catholic teacher contract?”

But the Cincinnati Archdiocese has repeatedly stated it is standing by its decision.
