'The Covenant of Works' explores the origins of the doctrine of God's covenant with Adam and traces it back to the inter-testamental period, through the patristic and middle ages, and to the Reformation. The doctrine has an ancient pedigree and was not solely advocated by Reformed theologians. The text traces the doctrine's development in the 17th century and its reception in the 18th, 19th, and 20th centuries. Fesko explores the reasons why the doctrine came to be rejected by some, even in the Reformed tradition, arguing that interpretive methods influenced by Enlightenment thought caused theologians to question the doctrine's scriptural legitimacy.
