A conference on the role on black churches in social justice issues has been going on in Ebenezer's facilities, Jones said.
King once preached at the historic Ebenezer Baptist Church, which is near the new church where the congregation now meets and where the flags were placed.
The King Center complex is near the eastern edge of downtown Atlanta. It is centered on Auburn Avenue, once a bustling center of commerce for Atlanta's African-American businesses and residents.
The center and church are a short walk from the home of Martin Luther King Jr.'s maternal grandparents, where the late civil rights leader lived for the first 12 years of his life
