Pandora, do read Yves Congar's MY JOURNAL OF THE COUNCIL - yes all 977 pages of it! Published by his sister after Congar's death. Day by day we see how this profound "back to the sources" theologian opened the bishops up to pastoral engagement with the contemporary world by letting them rediscover patristic thinking - the "new beginning" was a old as the Church! Congar's historical approach to theology was surely his most dynamic paradigm. His hand is clearly felt in many key Council documents from Lumen Gentium to Gaudium et Spes (yes with Chenu in Chapter 1!).
