’I do not seek to understand in order to believe; I believe in order to understand.’ He then wrote one of the most debated proofs for God’s existence in history.
Anselm’s mother was devout; his father was harsh. As a young man in Aosta, he wandered away from the faith, drifted across the Alps, and ended up at the monastery of Bec in Normandy almost by accident. Something about the place held him. He became a monk, then prior, then abbot, and then — much against his will — Archbishop of Canterbury. He reportedly wept when they told him. The job was political dynamite: two English kings, William Rufus and Henry I, tried to control Church appointments, and Anselm resisted both, spending years in exile rather than compromise. But his real legacy is what he wrote at night, after the arguments and the politics. The Proslogion contains his famous ‘ontological argument’ — that God is ‘that than which nothing greater can be thought,’ and that such a being must exist in reality, not just in the mind. Philosophers have been fighting about it ever since. Cur Deus Homo (‘Why God Became Man’) laid out a theory of atonement that shaped Western theology for centuries: humanity owes God a debt it cannot pay; only a God-man can pay it. These are dense ideas, but Anselm wrote them as prayers. He would think until he got stuck, then pray until the answer came. He described his method as ‘faith seeking understanding’ — not blind acceptance, but a mind on fire, reaching for God with every tool it has.
