Credo ut intelligam

Credo ut intelligam (alternatively spelled Credo ut intellegam) is Latin for "I believe so that I may understand" and is a maxim of Anselm of Canterbury (Proslogion, 1), which is based on a saying of Augustine of Hippo (crede, ut intelligas, "believe so that you may understand"; Tract. Ev. Jo., 29.6) to relate faith and reason. It is often accompanied by its corollary, intellego ut credam ("I think so that I may believe"), and by Anselm's other famous phrase fides quaerens intellectum ("faith seeking understanding").
