Supporters of a ballot measure which would ban gay marriage in North Carolina are taking their message to the pulpit on Sunday.

Vote for Marriage NC, the largest group working for passage of Amendment One, is calling on church leaders to preach in support of the amendment on Sunday and encourage congregants to vote early starting Monday during North Carolina's early-voting period.

If approved on May 8, Amendment One would bar the state from recognizing the relationships of gay and lesbian couples with marriage, civil unions and possibly domestic partnerships.

Supporters of the amendment are also asking churches to show a video in favor of the measure during church services.

The seven-minute video features several prominent religious leaders, including Dr. Mark Harris of the First Baptist Church in Charlotte, Dr. Patrick Wooden of the Upper Room Church of God in Christ in Raleigh, and Dr. Mark H. Creech, executive director of the Christian Action League of North Carolina. Also featured in the video is Tami Fitzgerald, executive director of the North Carolina Values Coalition.

Wooden, who is African-American, brushed aside the notion that the amendment is discriminatory, arguing that marriage by its nature is discriminatory.

“The truth is marriage does discriminate. And the only way we can make marriage a non-discriminatory institution is that we take all of the limits off,” he said.

Wooden also rejected comparisons to the Civil Rights Movement.

“We've never seen homosexual only water fountains. Homosexual only entry doors. There's no signs that say if you are homosexual go to the back. Homosexuals thrive in the country. They do well in this country. And I'm not opposed to that. But when it comes to the institution of marriage, I submit to Biblical authority.” (The video is embedded in the right panel of this page.

Wooden has previously faced criticism for saying sodomy is only wrong for gay men, gay men shove cellphones, baseball bats and gerbils up their anuses, and gay men need butt plugs to control their bowels.
