WASHINGTON - Jesus is black. Merging Marxism with Christian Gospel may show the way to a better tomorrow. The white church in America is the Antichrist because it supported slavery and segregation.

Those are some of the more provocative doctrines that animate the theology at the core of Trinity United Church of Christ in Chicago, Barack Obama's church.

Obama's speech Tuesday on race in America was hailed as a masterful handling of the controversy over divisive sermons by the longtime pastor of Trinity United, the recently retired Rev. Jeremiah A. Wright Jr.

But in repudiating and putting in context Wright's inflammatory lines about whites and U.S. foreign policy, the Democratic presidential hopeful didn't address other potentially controversial facts about his church and its ties.

Wright has said that a basis for Trinity's philosophies is the work of James Cone, who founded the modern black liberation theology movement out of the civil rights struggles of the 1960s. Particularly influential was Cone's 1969 book, "Black Theology & Black Power."

Cone wrote that the United States was a white racist nation and that the white church was the Antichrist for having supported slavery and segregation.

Today, Cone, a professor at Union Theological Seminary in New York, stands by that view, but also makes clear that he doesn't believe that whites individually are the Antichrist.

In an interview, Cone said that when he was asked which church most embodied his message, "I would point to that church [Trinity] first." Cone also said he thought that Wright's successor, the Rev. Otis Moss III, would continue the tradition.

Obama, 46, who is biracial, joined Trinity in his late twenties when he worked as a community organizer. He says he'll continue to worship there.

He and other Chicagoans have praised Trinity's role as a melting pot that brings together blacks and some whites from all levels of wealth and education, boasts a joyous and energetic choir, and is deeply involved in community work, such as helping the homeless, the incarcerated and those touched by HIV and AIDS.

But Trinity has a history. Its affiliation with the United Church of Christ makes it part of a liberal, mostly white denomination that was the first in America to ordain gays, women and blacks as ministers.

Trinity goes further, however, embracing black liberation theology and its emphasis on empowering oppressed groups against establishment forces.

In that and related doctrines, the church and some of its guiding thinkers at times have been socially ahead of the curve and other times outside the mainstream of American religious and political thought.

For example, the 8,000-member congregation embraces the idea that Jesus was black. It has historically supported left-wing social and foreign policies, from South Africa to Latin America to the Middle East.

It isn't clear where Obama's beliefs and the church's diverge. Through aides, Obama declined requests for an interview or to respond to written questions about his thoughts on Jesus, Cone or liberation theology. Trinity officials also didn't respond to requests. Wright hasn't been giving interviews since the controversy broke.

Obama's Illinois and U.S. Senate voting records and his speeches suggest that, if elected president, he'd take a liberal but mainstream line and seek partisan bridge-building rather than agitation as his style.

It's possible that Obama joined Trinity as much because it gave him credibility as a newcomer to south side Chicago's black community as for its particular theological teachings.

"As a community organizer, would people join Trinity? Yes." said Dwight Hopkins, a Trinity member and liberation theology professor at the University of Chicago's divinity school. (He said he'd contributed $25 to Obama's campaign.)

However, "someone who wanted to run for public office would think twice about intentionally using Trinity as a leverage," Hopkins said. "When it's Election Day, all the politicians come to Trinity. But not every day."
