Thirty-one Pennsylvania Methodist ministers plan on jointly officiating over the marriage of a gay couple to show solidarity with a colleague preparing to stand trial for presiding at his gay son's wedding.

The Rev. Frank Schaefer, pastor at Zion United Methodist Church of Iona in Lebanon, Pennsylvania, faces suspension or the possibility of being defrocked for presiding over the wedding of his son Tim.

The wedding took place in 2007 in Massachusetts, which legalized gay marriage in 2004.

A complaint was filed against Schaefer by one of his congregants just 26 days before the church's statute of limitations would have expired.

He is accused of breaching the church's Book of Discipline, the denomination's law book, which prohibits clergy from performing “ceremonies that celebrate homosexual unions.”

Schaefer's church trial begins November 18.

According to The Philadelphia Inquirer, the names of the couple and the location of the ceremony are not being made public. Another ten ministers are considering joining the original 31, said the Rev. David Brown of the Arch Street United Church in Philadelphia.

“The more we get, the harder it will be for the church – it's not impossible – the harder it will be to go after any one person to take away their [religious] orders,” Brown told the paper.

Pennsylvania currently does not allow gay couples to marry.
