Scientific perspectives are often perceived to challenge biblically-based cosmologies and theologies. Arthur Peacocke, biochemist and theologian, recognized that this challenge actually represents an opportunity for Christian theology to re-envision and reinterpret its traditions in ways that take into account scientific theories of evolution. In the course of his career, Peacocke offered a new paradigm for the dialogue between theology and science. This paper explores his proposals, in particular his theories of language, the God-world relation, and the nature of God, and exemplifies the impact these proposals has on his theological insights.
