The questions that the great Protestant theologian Karl Barth addressed to "Rome" in 1966 did not meet with discussants either interested, or ready to answer. Vatican II (1962-1965) had just come to an end and "Rome" was more concerned with the dissemination of the Council's message than with a thorough critical analysis of its contents. There is no question that the answers, published only today, are belated, but not wanting in interest or efficacy in order to clarify the doubts, remove the reservations, dismiss the uncertainties of as many as are not content with hackneyed praise, but wish to obtain a firm grasp on truth.
