Without a doubt, the late Edward Schillebeeckx (1914-2009) remains one of the most important and inspiring theological voices of the twentieth century. Apart from his influential books still widely read, the name of Schillebeeckx is constantly linked to the renewal of church life and theology that occurred during the Second Vatican Council. The present critically annotated edition by Dr. Karim Schelkens - containing both the original Dutch text and an English translation - now makes Schillebeeckx' private notes, jotted down during the first two council periods, readily available for a wider public, thereby offering its readers a unique possibility to enter into the thought world and the activities of this theological giant. The edition is prepared with the support of the Edward Schillebeeckx Foundation, and holds a preface by Prof. Mathijs Lamberigts as well as an introduction by Schillebeeckx' biographer, Prof. Erik Borgman.
