This project is a historical analysis of the development of diversity, equity, and inclusion at Saint James School, established in 1842 at "Fountain Rock'' plantation in Hagerstown, Washington County, Maryland. It starts from the conception of the "Church school" by William Augustus Muhlenberg (1796-1877) and goes·through the present time in the tenure of the Tenth Headmaster, Donald Stuart Dunnan (b. 1959). Saint James School identifies as "an Episcopal school within the Anglo-Catholic tradition" that "remains faithful to our historic identity as a Church school." The purpose for this project is to bring forward the "blind spots'' in the School's historic Oxford Movement and present-day Anglo-Catholic heritage and Muhlenberg's Church School Movement. For Saint James School to remain what it has been, but in a changed way, it must be theologically orthodox, liturgically traditional, and socially progressive governed by the Gospel of Jesus Christ. Muhlenberg's vision is still worth maintaining, but with a more comprehensive meaning and application. Saint James School can remain faithful to its stated mission of being a Muhlenbergian Church school whose Christianity is the basis for its inclusivity and Anglican affiliation and ecumenism enabling the School to prepare young people of all races, sexes, and gender identities to be "leaders for good in the world."
