Bethany was founded July 28, 1909 as a community where members of the Church of the Nazarene could express their religious beliefs without interference by non-members. The area was once a grove of blackjack oak trees known as Council Grove, where American Indian tribes held war councils. The community quickly established the Oklahoma Holiness College (now Southern Nazarene University, SNU). two other institutions were soon established, the Oklahoma Orphanage (now the Children's Center, a medical facility) operated by Mattie Mallory, and the Nazarene Rescue Home for unwed mothers.
