The purpose of this study, which is primarily a redaction-critical inquiry, is to examine all of Mark's references to the kingdom and thus to arrive at an understanding of the idea that he has of it. The book is divided into 5 chapters: (1) passages proclaiming the kingdom and its hidden presence, (2) the mysterious activity of the kingdom among men, (3) the ethical demands of the kingdom, (4) the liturgical celebration in the community, (5) the kingdom as a future reality.
