In this work McGrath commits himself to an approach that seeks to avoid the use of contemporary views of religion as found in the work of the distinguished Ian Barbour and Arthur Peacocke, keeping instead to a classic Christian theological formulation (i.e., traditional credal Christian orthodoxy), which is a position closer to John Polkinghorne according to McGrath. Also when relating Christianity and science, the three volumes stress the "provisionality" of scientific understanding, findings, and conclusions. This sort of provisionality makes relating Christianity to science very different from relating Christianity to fairly settled views such as Platonism and Aristotelianism.
