Abstract
This published lecture builds upon a mutuality model for the relationships between theology and science. The basic idea is that theology and science (natural and social) are colleagues in helping to develop a Christian worldview. Because both use informal reasoning, there are avenues in which they can reasonably influence each other. I also discuss what it means to "redeem reason" since this lecture was originally part of the Redemption of Reason conference. These preliminary moves set up a focused example, drawn from Christology and astronomy. Accepting the view that the cosmos is bio-friendly, and assuming there may well be intelligent life on other planets, I discuss what the implications of this are for Christology. I conclude that we do not need to alter our orthodoxy Christology, but we do need an expanded Christian imagination.
