How does The Great Theatre of the World present the idea that people play roles before God?

In The Great Theatre of the World (El gran teatro del mundo), Pedro Calderón de la Barca utilizes the metaphor that "all the world is a stage" to illustrate a profound theological and social hierarchy.1

The play presents the idea that human life is a performance directed by God, wherein every individual is assigned a specific role to play before Him. This allegorical structure serves to reinforce the concept of a divinely ordained order, where one's earthly existence is defined by the fulfillment of their assigned part within the grand design of the world. By framing human life as a theatrical production, Calderón emphasizes that individuals are accountable to the ultimate Author—God—for how they perform their duties and navigate their stations in life.12
