In the midst of the tremendous vitality that today's Christians are showing, one set of problems emerges over and over again: how to be faithful both to the contemporary experience of the gospel and to the tradition of Christian life that has been received. How is the community to go about bringing to expression its own experience of Christ in its concrete situation? And how is this to be related to a tradition that is often expressed in language and concepts vastly different from anything in the current situation? These problems are the subject of this book.
