The document presents an economic model of God and humanity as optimizing agents within the context of Judeo-Christian religious beliefs. It analyzes four primary belief archetypes or "contracts" between God and humanity: 1) Ex post contracts where rewards are conditional on observed good works, 2) Ex ante contracts without penalties for reneging, 3) Ex ante contracts with penalties, and 4) Transformed faith contracts emphasizing divine gifts over works or penalties. The model generates testable predictions about how these contracts differentially affect individuals' incentives and behavior based on their strength of faith or doubt. Empirical analysis of individual survey data provides some support for the model's counterintuitive predictions.
