Book excerpt: A Scientific Theology is a groundbreaking work of systematic theology in three volumes: Nature, Reality, and Theory. Written by one of the world's best-known theologians, these volumes together represent the most extended and systematic exploration of the relation between Christian theology and the natural sciences yet produced. Thoroughly ecumenical, this will be a significant work for Catholic, Orthodox, Protestant, and evangelical readers. The work is marked throughout by a sustained and critical engagement with the history and philosophy of the natural sciences and by a passionate commitment to the legitimacy of theology as an academic discipline.
