"Interdisciplinary education" has become a catchphrase among Christian educators, but what does such a practice look like in reality? The authors, a systematic theologian and a biblical scholar respectively, reflect on their shared experiment in teaching students the doctrine of God.

They call for scholars to strive to talk together across disciplinary boundaries in order to foster students who think in theologically sophisticated ways. (Contains 1 endnote.)
