It can be pleasing when you find a meeting of minds, as it were, between science and religion, after all, there is no need for them to be at odds, and at best they can act as a corrective and a refiner, one to the other. Religion can humanize science, can bring to it ethical and spiritual insights that otherwise it might lack. Science can bring to religion the challenge of intellectual rigour – otherwise Galileo would still be condemned and we would still think the world flat.But together, and working in harmony, they can bring so much to our understanding of the world and our place in it. In John's Gospel, and in the lesson of the grain of wheat, we find one such example – of the two working hand in hand.
