Why did God become man? Why would the Creator of everything that exists, assume a human nature, and suffer for those who had turned away from Him? In this timeless Catholic masterpiece, Cur Deus Homo — Why God Became Man, St. Anselm of Canterbury answers these and other deep questions at the heart of the Christian faith.

Written at the close of the 11th century, and structured in the form of a dialogue between the saint and an inquirer named Boso, this brilliant treatise is one of the most profound theological works produced by the medieval Church.

With devotion and clarity, St. Anselm explores the mystery of the Incarnation and shows the necessity of Christ’s sacrifice for the redemption of humanity. No mere man but only God Himself, as man, could satisfy the debt of sin and restore humanity to the life of grace.

The reader comes to see how Christ’s life, death, and resurrection are not just historical events, but the merciful fulfillment of divine justice. Sin is more than wrongdoing—it is a debt to God’s justice. And yet, God, in His infinite love and wisdom provides the way for that debt to be paid: the perfect and voluntary sacrifice of the God-man.
