NASHVILLE, Tenn. (AP) - It has been more than half a century since the Rev. Martin Luther King Jr. gave a poignant speech about the racial divisiveness among Christians.
    
King called Sunday morning services "the most segregated hour of Christian America."
    
Most studies and experts say it's roughly the same today, though some church leaders and congregations are still trying to branch out and attract followers of all colors.
    
One white Georgia Baptist pastor, Michael Catt, says it's not being honest to lead a church in a mostly black city and look out on a white congregation.
    
He and a fellow black pastor, Daniel Simmons, now swap pulpits and their congregations often meet together for special occasions. They hope to break down the barriers churches have faced for decades in worshipping together.
