Camp Winnataska was operated after its founding in 1918 by the Birmingham Sunday School Council. The camp has always been run as an interdenominational camp. The Birmingham Sunday School Council was composed of Presbyterians, Episcopalians, Methodists, and Baptists. The camp--and its leadership--has always included Catholics, Lutherans, and other Christian denominations. The camp is open to anyone who wishes to attend. Because Winnataska is interdenominational, we are careful not to compel campers to agree to any religious or denominational doctrine.

The intent is fulfilled in the following ways at Camp Winnataska's six summer sessions: Sunday morning church (for leaders and staff), morning Bible study, Hillside inspirational vespers & hymns, evening hut Bible devotions, and singing Christian songs.
