Some say the purpose of church is to deliver the word of God. If so, what's the role of music in the service?
"The music has always been a part of God's way of getting people's attention," says Bishop Calvin Worthem, pastor at the Church of the Living God in Toccopola, Miss. "Sometimes he speaks through the thunder, the lightning, and sometimes he speaks in the music."
Amid chanting and drumming, a crowd gathers in Sao Paulo and waits for the gods to come to them from the spirit world.
They are celebrating a sacred festival day in honor of Omulu, a deity of life and death. The women wear white dresses with crinolines, colorful belts and headdresses. The men wear lace, pajama-style suits. They sing and dance in a circle for hours; the room gets warmer, the chanting more intense.
Suddenly, they are here: Orixas have possessed the chosen among the faithful. They are spirit gods, the deified ancestors who link humans to the other world.
In 2007, a breakaway extremist offshoot of the Mormon Church called the Fundamentalist Church of the Latter Day Saints made national news. Police raided an FLDS compound in Texas where they found hundreds of women and girls. The church's leader, Warren Jeffs, was sentenced to life plus 20 years behind bars for sexually assaulting children.
