The demand that epistemic support be explicated as rational compulsion
has consistently undermined the dialogue between theology and science
. Rational compulsion entails too restrictive a form of epistemic supp
ort for most: scientific theorizing, let alone interdisciplinary dialo
gue. This essay presents a less restrictive form of epistemic support,
explicated not as rational compulsion but as explanatory power. Once
this notion of epistemic support is developed, a genuinely productive
interdisciplinary dialogue between theology and science becomes possib
le. This essay closes by sketching how the Big Bang model from cosmolo
gy and the Christian doctrine of Creation can be viewed as supporting
each other.
