Religion is an elusive subject for the historian. It, like comedy and tragedy, has two faces. One, the persona or external face, manifests itself in many ways: community and denominational development, organization, membership, and practice; shared dogma or beliefs; communal worship and prayer; individual and communal service both within and outside denominational boundaries; the relation to the body politic and society in general; interdenominational cooperation and conflict; the arts, etc. The other face, the hidden or interior face, reveals a man's or woman's inner spiritual journey. Life as a pilgrimage or spiritual journey is one of the most familiar themes in religious literature.
