The headway of reform in English-speaking Cathohcism owes a great deal to the intrepidity of Fr Hans Küng's publishers. The spectacular popularity of The Council and Reunion, the paperback which made his name, demonstrated his charismatic audacity in bringing out into the open what a vast number of reflective Catholics had long been nervously and fumblingly trying to articulate for themselves. Of course extravagant claims have been made for him: he is not the long-awaited new Aquinas nor the anti-Christ. He is a hardworking theologian with some good ideas, as the only two major studies he has so far written bear witness. The first of these is Rechtfertigung (1957), a confrontation of Karl Barth's doctrine of justification with Catholic teaching; and the second is Strukturen der Kirche (1962), an attempt to situate the papacy with regard to the episcopal college and the general Council inside the mystery of the Church. Neither of these books is yet available in English.
