'In science, it is well-articulated proposals that lead ultimately to conviction. What is true about the scientific understanding of the physical and biological world is also true of theology's quest for an understanding of God'. At the outset, Polkinghorne provides a helpful overview of the ways scientists approach and dialogue with theology. He then shows how modern physics shares with the Trinity many relationary elements, and notes the veiled nature of quantum reality. He also considers the scriptural element from a scientific perspective. A discussion of the central role of the Eucharist provides an experiential and human dimension.
