In accordance with the intention of the University’s founders, Duke Chapel maintains an explicit Christian identity and mission. For many years, the Chapel has been a center of faith Trinitarian Christian worship. Its architecture and iconography identify it unmistakably as a Christian place of worship. … In the context of these clear historic Christian commitments, Duke University is quite properly a place where people of many different faiths, as well as those of no religious faith, work and study together. The University is committed to creating a shared, mutually enriching life in which various historic religious traditions can thrive and learn from one another as part of a common commitment to education and the pursuit of wisdom. The University is not a community in which differences are suppressed; it is a vibrant “city” in which the particular ideas and traditions of different communities can be expressed openly, discussed respectfully, and evaluated critically. In this spirit, we in the Divinity School strongly support the presence of various spaces on campus where diverse historic religious faiths can be practiced in a public way. Such a commitment does not, however, necessarily lead to endorsement of the decision to explicitly identify the Chapel with another faith tradition.
