St. Anselm of Canterbury
Father of Scholasticism · 1033–1109
For faith seeking understanding — fides quaerens intellectum.

In their words
Faith seeking understanding.
Life
Benedictine monk, abbot of Bec, and Archbishop of Canterbury. His Proslogion offered the famous ontological argument, and he defined theology itself as "faith seeking understanding" (fides quaerens intellectum) — the conviction that believing is not opposed to thinking but is its starting point.
A prayer
From the Proslogion
Be it mine to look up to thy light, even from afar, even from the depths. Teach me to seek thee, and reveal thyself to me, when I seek thee; for I cannot seek thee, except thou teach me, nor find thee, except thou reveal thyself. Let me seek thee in longing, let me long for thee in seeking; let me find thee in love, and love thee in finding.
