From www.nps.gov:
Throughout its long history, Ebenezer Baptist Church has been a spiritual home to many citizens of the "Sweet Auburn" community. Its most famous member, Martin Luther King, Jr., was baptized as a child in the church. After giving a trial sermon to the congregation at Ebenezer at the age of 18 Martin was ordained as a minister. In 1960 Dr. King, Jr. became a co-pastor of Ebenezer with his father, "Daddy" King. He remained in that position until his death in 1968. As a final farewell to his spiritual home Dr. King, Jr.'s funeral was held in the church.
