This study examines the twin theories of coinherence and substitution that Williams developed
in his seven novels. The theories are mystical and theological in their development. Williams
was deeply influenced by The Inklings the literary group which he belonged to while he was
with the Oxford University Press during WW II. I have used C.G. Jung's ideas about religion as
well as Soren Kierkegaard's view of Christian existentialism. The study presents Williams' life
in brief his work at Oxford UP his intellectual development. There are two chapters devoted
to a close examination of each novel and its relationship to his theories and a chapter which
reviews the existing Williams criticism. The final chapter is a conclusion for the work.
