This is an excellent book written by a top Catholic theologian about the greatest Protestant theologian of the 20th century- Karl Barth. It will serve as a good introduction into the theology and work of Barth. Written in a style which allows Barth to speak for himself this volume will serve as a primer for both Catholic and Protestant Christians alike regarding not only Barth's theology but also a vision for the Church which helps evaporate the disfiguring fog of division within the Church by pointing to the way taken by our Savior- Christ is the way (Jn. 14:6). The question is: Can we follow the implications drawn out so clearly in this book that we are willing to give our all to follow Christ?
