WASHINGTON – They love President Obama. But when it comes to his support for same-sex marriage, some of the nation’s leading African-American clergy are divided, sometimes passionately.

Meeting in Washington on Thursday, the Conference of National Black Churches couldn’t reach agreement. As a group, the only thing they found conclusive was that the Bible — Old and New Testament — presents no consensus when it comes to homosexuality. But most of the ministers, pastors and theological scholars expressed firm positions on marrying same-sex couples.

“I love all homosexual brothers and sisters, but my discipline says I can’t marry them,” said Bishop John Adams, an African Methodist Episcopal minister and former conference chairman. “Same-sex marriages are not being approved by the Christian community because it is a contradiction of creation. … The species continues by the procreation of male and female.”

Michael Eric Dyson, a Georgetown University sociology professor with a doctorate in religion from Princeton, scolded African-American clergy members who rail against gay marriage and homosexuals yet take donations from them and allow them to be ushers and to sing in or direct church choirs.

“Some of the most homophobic preachers there are probably gay themselves,” Dyson told the group. “I’m not saying you must be secretly gay. My point is that the gay self has been so constructed and demonized that even the gay person, as a rite of passage, hate(s) the gay self … in order to gain legitimacy in black church circles.”

Thursday’s public debate reflected one already taking place in some form in African-American churches across the country since Obama, who previously opposed gay marriage, announced his support this month.

Obama’s stance set off concerns about how African-Americans, who have generally opposed same-sex marriage at higher rates than whites have in the past, would react in an election year. An ABC News/Washington Post poll released last week found that 59 percent of African-Americans now support gay marriage, up from 41 percent earlier this spring and last summer.

While attitudes may be changing within the African-American community, its churches appear to be a different matter.

The nine denominations of the Conference of National Black Churches, which reach 10 million people, all oppose gay marriage, said the Rev. Dr. Franklyn Richardson, the group’s chairman.

Adams, the African Methodist Episcopal minister, said he supported Obama despite the president’s gay-marriage stance.

“I love the president,” he said. “But I disagree with him.”
