What do worship services and theater have in common? A highly relevant theoretical study on worship. The worship service is not a theatrical performance. Yet, the similarities are profound. In discourse with theater studies, Ursula Roth defines the theatricality of the Christian worship service. To what extent is the worship service a "staging," and what "play" is being performed? What "role" does the liturgist play, and what role does the congregation have? By clarifying these questions, a picture of the Christian worship service is developed, highlighting aspects of the liturgical event that have previously been underexplored. A highly relevant theoretical study on worship with cultural scientific breadth.
