Alister McGrath defends the idea that creation (or “nature”) is a real entity that discloses knowledge in such a way that shapes the knowledge it discloses. In other words, ontology structures epistemology without negating the latter. Echoing Thomas Torrance, we know “kata physin.”
He begins with his own life-journey from studying chemistry at Oxford to studying theology–and becoming a Christian along the way.
Contra Hellenism and Orientalism, since creation is contingent, the real can be found by acknowledging nature’s contingency (McGrath 51). For Greeks, to get to the real was to get beyond appearances and nature. For the creation-tradition, however, the opposite was the case. The natural order possesses its own goodness and rationality.
Creation (or “nature”) finds itself within an interlocking network of divine and human rationality (62). Following the Hebrew writers, particularly Job (38ff), creation is linked with the idea of God’s “ordering.” This ordering is not the result of God’s being under necessity, but is rather contingent.
McGrath defends natural theology but in a new way. Natural theology isn’t looking at a squirrel and then deducing God’s simplicity. Rather, it begins with revelation and sees the natural world as disclosing real truths.
The book then moves from “nature” to “theory.” McGrath criticizes communitarian approaches like Lindbeck and to an extent, Barth. He also interacts with John Milbank and Alasdair McIntyre.
