It's a Sunday morning at the Abyssinian Baptist Church, a famous African-American church in the Harlem area of New York City. The organist plays as hundreds of worshippers stream into the pews. The Rev. Calvin O. Butts III steps to the pulpit.
"Now may we stand for our call to worship," says Butts, as he begins a powerful three-hour service filed with music, dancing, prayers and preaching. "How good and pleasant it is when all of God's children get together."
