Becoming and Being presents an analysis and comparison of two influential modern approaches to the doctrine of God. Although they are in many respects diametrically opposed, the one finding its basis in biblical revelation and steeped in the tradition of trinitarian reflection, the other relying on pure speculative reason, there are numerous and surprising points of contact. The second edition offers a new conclusion by the author, in which he responds to his critics, and reflects on how his views have changed and remained the same in the intervening years. While providing useful portraits of its two central thinkers, Barth and Hartshorne, the book will also serve as a fine introduction to the rational basis of theology, as well as providing insight into some of the perennial questions arising from belief in God. Reviews from the first edition: 'A meticulous essay, marked by elegant economy of words, intimate knowledge of its subject, incisive comment and considerable philosophical agility.' -- Churchman 'It is a rare treat to read a book by an English theologian written with a genuinely theological rationality - it stands head and shoulders above so much recent writing.' -- The Way 'An excellent contribution to the modern debate about the nature of Christian theology.' -- Heythrop Journal Colin E. Gunton (1941-2003) was Professor of Christian doctrine at King's College London. He authored twelve books including The Christian Faith and The Triune Creator.
