Anselm of Canterbury

Anselm of Canterbury (1033–1109) was an Italian-born Benedictine monk who became Archbishop of Canterbury and is widely credited as a founder of Scholasticism — the medieval tradition of applying rigorous philosophical reasoning to theological questions. His work bridged the faith-centered theology of the early Church Fathers and the systematic philosophical theology that would reach its zenith with Thomas Aquinas, though this recognition came largely after his own lifetime. 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. Anselm's Proslogion, written around 1077–1078, 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 engaged philosophers from Descartes and Kant to contemporary analytic thinkers. His Monologion offers a complementary rational investigation of God's nature. Both works embody his governing method: fides quaerens intellectum — faith seeking understanding. As Archbishop, Anselm spent much of his tenure in direct conflict with English kings over the Investiture Controversy — the question of whether secular rulers could appoint bishops. He was exiled twice: first by William II from 1097 to 1100, then by Henry I from 1105 to 1107. During his first exile he attended the Council of Bari, where he helped guide the Greek Catholic bishops of southern Italy to adopt Roman rites. He also worked, with only partial lasting success, to establish Canterbury's primacy over the Archbishop of York. His most enduring theological contribution may be Cur Deus Homo (Why God Became Man), which articulated the satisfaction theory of Atonement: that Christ's death was necessary to satisfy the honor of God, which human sin had offended. This framework shaped Western Christian understandings of salvation in both Catholic and Protestant traditions for centuries. Anselm was canonized in 1163 and declared a Doctor of the Church by Pope Clement XI in 1720.
