The pastor chosen by President-elect Barack Obama to give the inaugural invocation backed Proposition 8, which banned gay marriage in his home state of California. But he did so belatedly, with none of the enthusiasm he brings to fighting AIDS and illiteracy.
When other conservative Christians held stadium rallies and raised tens of millions of dollars for the ballot effort, there was no sign of Warren. Neither he nor his wife, Kay, donated any of their considerable fortune to the campaign, according to public records and the Warrens' spokesman.
In fact, his endorsement seemed calculated for minimal impact. It was announced late on a Friday, just 10 days before Election Day, on a Web site geared for members of his Saddleback Community Church, not the general public.
He has spoken out against the use of torture to combat terrorism. He has joined the fight against global warming and, encouraged by his wife, has put his prestige and money behind helping people with AIDS. The Warrens have done so at a time when a notable number of conservative Christians still consider the virus a punishment from God.
"If you want to save a life, I don't care what your background is and I don't care what your political party is," Warren said in a recent interview with The Associated Press. "I think some of these humanitarian issues transcend politics, or ethnic or religious beliefs."
While many religious conservatives openly condemn Islam as inherently evil, Warren reaches out to the American Muslim community. This past Saturday, he gave the keynote address at the convention of the Muslim Public Affairs Council, based in Los Angeles.
"His social consciousness is somewhat left of center, but his theological, ethical stance is right of center," said the Rev. William Leonard, a critic of the Southern Baptist Convention and dean of Wake Forest Divinity School in North Carolina. "That's the thing that makes him potentially a bridge person."
Warren's outlook has come at a price. Many from the Christian right don't trust him.
The fact that the true homophobes, bigots and authoritarians on the religious right don't trust him definitely raises his standing my eyes.
