Anselm of Canterbury

Anselm of Canterbury (1033–1109) was an Italian-born Benedictine monk who became Archbishop of Canterbury and is often called the 'Father of Scholasticism' — the great medieval tradition of applying rigorous philosophical reasoning to theological questions. His work marks a watershed in the history of Western thought, bridging the gap between the faith-centered theology of the early Church Fathers and the systematic philosophical theology that would reach its zenith with Thomas Aquinas. Born in Aosta in the Kingdom of Burgundy (modern-day northwestern Italy), Anselm entered the Benedictine monastery of Bec in Normandy in 1060, drawn by the reputation of its prior, Lanfranc. He succeeded Lanfranc as prior in 1063 and as abbot in 1078, transforming Bec into one of the most important centers of learning in Europe. In 1093, he was appointed Archbishop of Canterbury — a position he initially tried to refuse and in which he spent much of his tenure in conflict with Kings William II and Henry I of England over the issue of lay investiture (the right of secular rulers to appoint bishops). Anselm's philosophical contributions are profound. His 'Proslogion' contains the famous 'ontological argument' for the existence of God — that God is 'that than which nothing greater can be conceived,' and that such a being must necessarily exist. This argument has fascinated and divided philosophers from its inception to the present day, with figures as diverse as Descartes, Kant, and contemporary analytic philosophers engaging with it. His 'Monologion' provides a complementary rational investigation of God's nature. Perhaps his most enduring theological contribution is 'Cur Deus Homo' (Why God Became Man), which articulated the 'satisfaction theory' of the Atonement — the idea that Christ's death was necessary to satisfy the honor of God, which human sin had offended. This theory profoundly shaped Western understandings of salvation, influencing both Catholic and Protestant theology. Anselm was canonized in 1163 and declared a Doctor of the Church in 1720.
