The tensions between our two authors start to rise. Ruse dismisses natural theology and proofs for the existence of God. Faith or nothing, and that means nothing because faith does not work. Davies responds by pointing out that there is biblical evidence for natural theology, and turns to Aquinas for guidance. The saint agrees that faith trumps reason and is enough alone for Christian belief, but argues also that reason, natural theology, has its place. It can supplement and back up the commitments through faith. There is therefore no conflict between reason and faith. Both have their role. In any case, argues Davies, scientists make faith commitments, having to start somewhere without prior proof, so in the end science is in the same business as religion. Ruse responds that the commitments of science and the commitments of religion are entirely different. The Christian cannot end the case by using this line of argument.
