JACKSON, Miss. (AP) – Efforts to restore a United Methodist center that was destroyed five years ago by Hurricane Katrina are now threatened by the BP oil spill in the Gulf of Mexico. Gulfside Assembly in Waveland, Miss., was founded in 1923 as a boys’ boarding school by the first black elected bishop of the Methodist Episcopal Church. During the civil rights era, it was one of the few places in the South where blacks and whites felt free to mingle. The assembly’s latest venture — a $200 million retirement community, ministry and conference center — has suffered a setback because of the oil spill. Gulfside will hold an interfaith prayer and worship service at the site of the project Sept. 17.
