A group of religious leaders in Maryland on Wednesday launched an effort to oppose a proposed bill that would make Maryland the seventh state to legalize gay marriage, The Washington Post reported.

Maryland Marriage Alliance is led by Pastor Derek McCoy, executive director of the Maryland Family Alliance.

“We will not lie down in the face of renewed efforts to redefine this institution,” McCoy said at an early morning Wednesday news conference. “Marriage is defined as between one man and one woman.”

A gay marriage bill ran aground earlier this year in the House of Delegates after it narrowly cleared the Senate.

Democratic Governor Martin O'Malley has pledged to shepherd the bill through the Legislature during the upcoming legislative session, which opens in January.

The new coalition enjoys the support of the Maryland Catholic Conference and the National Organization for Marriage (NOM), two groups which strongly opposed the legislation this year.

Rev. Victor Kirk, senior pastor of Sharon Bible Fellowship in Temple Hills in Prince George's County, said he was prepared for a second round.

“With all humility, let me say: Bring it on,” he said.

Lawmakers in nearby New York approved a gay marriage bill since Maryland's defeat in the spring, possibly boosting the bill's chances of passage next year.
