"The presentation of this study of Barth by an American scholar...is therefore most refreshing. Here we have Barthian theology and philosophy examined under the light of Catholic thought and witin the context of the favorable climate of the American dialogue. Sebastian Matczak limits his treatment to the fundamental - and highly disputable - question upon which rests Barth's entire theological synthesis: the problem of how we can know God in His Divine Existence." - publisher.
