An Anglican priest in charge of the Parish of the Claydons in the Diocese of Oxford, Rodney D. Holder formerly worked as a scientific consultant to the British Ministry of Defense (MOD). He read mathematics at Trinity College, Cambridge, and earned a D.Phil. in astrophysics at Oxford in 1978. He remained at Oxford to do post-doctoral research on accretion of intergalactic gas by Earth’s galaxy. After fourteen years with Electronic Data Systems (formerly Scicon, Ltd.) working with the MOD on the application of mathematical modeling techniques to defense studies, he returned to Oxford and took a first-class degree in theology in 1996. Upon completion of his ministerial training the following year, Dr. Holder was ordained in Coventry Cathedral. After four years as a curate in South Warwickshire and a sabbatical term as chaplain of the English Church in Heidelberg, he was appointed to his present post in 2002. He explored ways in which science and faith may complement each other in Nothing but Atoms and Molecules? (1993). The author of a number of articles, both on science and on theology, appearing in academic journals, his latest book, God, the Multiverse and Everything, was published in 2004 by Ashgate. It examines the fine-tunings of natural law that were necessary for life to evolve in our universe and uses Bayes’s theorem, a classic tool for determining probability, to assess their metaphysical significance.
