For over fifteen hundred years, Christians saw the bible as the primary source of knowledge, but in the seventeenth Century the beginnings of a scientific revolution began to challenge the Christian view of the world. Eminent scientist Colin Blakemore interviews esteemed scholars and Churchmen in order to understand how Science has transformed Christianity over the last four centuries. He shows how scientists born of the Enlightenment realised that the laws of the universe were there to be discovered, not read about in the Bible. He argues that Science is the biggest challenge Christianity has ever had to face, and that it will eventually make religion unnecessary.
