In the last decade a number of publications have appeared regarding the life and work of the French Dominican Yves Congar. The present essay presents the “young Congar” of the 1930s, in particular his vision of what Catholic theology should be. The author defends the thesis that it is Congar who initiated the “program” of (the first phase of) the so-called nouvelle théologie (“new theology”). After a general survey of the central features of the nouvelle théologie and its development, the author gives an overview of the three ways in which Congar is to be understood its pioneer and representative.
