"Among all the recent publications about Karl Barth, John Webster's discussion of this theological giant invites our attention as a highly authoritative guide. It offers a thoroughgoing summary of Barth's theological and ethical contributions, replete with analysis and engagement with his critics, all in a remarkably short span...This is a very fine textbook indeed. The summaries are masterful and the quotations judicious, inviting further reading of the primary sources, which is one of Webster's stated goals. There is also a useful summary of primary and secondary literature on Barth, with comments in preface about publications in the four years since the first edition of this book and about forthcoming texts. The book is so encyclopedic that it might be best used as a supplement to other introductions to Barth, but it is an excellent resource for anyone who wishes to engage with this outstanding Christian thinker." —Justyn Terry, Anglican Theological Review
