It looks like the Big O. fooled us with his claim of being an infrequent attender at Rev. Jeremiah Wright’s jeremiads vs. U.S. and all things middle class:

President-elect Barack Obama said in 2004 – while he was a state legislator running for a U.S. Senate seat – that he attended services at Trinity United Church of Christ every week.
 
This is in contrast to what Obama, as a presidential candidate, said this year after controversial anti-American remarks by the Rev. Jeremiah Wright surfaced. Obama then told news outlets that he did not attend the church frequently and was not aware of Wright’s comments.

Sun-Times religion writer, now columnist posted the full interview at Belief.net, where she explains:

At 3:30 p.m. on Saturday, March 27, 2004, when I was the religion reporter (I am now its religion columnist) at the Chicago Sun-Times, I met then-State Sen. Barack Obama at Café Baci, a small coffee joint at 330 S. Michigan Avenue in Chicago, to interview him exclusively about his spirituality. Our conversation took place a few days after he’d clinched the Democratic nomination for the U.S. Senate seat that he eventually won. We spoke for more than an hour. He came alone. He answered everything I asked without notes or hesitation. The profile of Obama that grew from the interview at Cafe Baci became the first in a series in the Sun-Times called “The God Factor,” that eventually became my first book, The God Factor: Inside the Spiritual Lives of Public People (FSG, March 2006.) Because of the staggering interest in now President-Elect Obama’s faith and spiritual predilections, I thought it might be helpful to share that interivew, uncut and in its entirety, here.

In the course of the interview, Falsani asked if he still attended Trinity Church.

OBAMA:
Yep. Every week. 11 oclock service.

Ever been there? Good service.

I actually wrote a book called Dreams from My Father, it’s kind of a meditation on race. There’s a whole chapter on the church in that, and my first visits to Trinity.

Which church he had to abandon, as we know.
