St. Anselm of Canterbury

St. Anselm of Canterbury’s satisfaction theory of redemption, detailed in his work Cur Deus homo?, fundamentally shifted the focus of atonement from the Devil to God.
The earlier "ransom theory" posited that humanity owed a debt to the Devil due to the fall, and that Christ’s death served as a ransom payment to secure human freedom from the Devil’s grasp.1
Anselm rejected this, arguing instead that:
- The Nature of the Debt: Sin is an offense against the infinite majesty of God, not a debt owed to the Devil. Because the offense is infinite, finite humanity is incapable of making the necessary satisfaction.23
- The Necessity of the God-Man: Reconciliation required someone who was both human (to represent the guilty party) and God (to possess the infinite merit required to satisfy the offense).2
- The Role of Christ: Christ’s death on the cross was not a payment to the Devil, but a voluntary act of infinite merit that restored the relationship between God and humanity.23
Anselm’s framework became a cornerstone of Western theology, influencing both Roman Catholic and Protestant thought.2
